What Is High Frequency Inverter Board?
A high-frequency inverter board is a power electronic device that converts direct current (DC) into alternating current (AC). Its core feature is the use of high-frequency switching technology (typically above 20kHz), which rapidly switches power devices (such as MOSFETs and IGBTs) on and off to achieve power conversion. Compared to traditional low-frequency inverters (50/60Hz), high-frequency inverter boards significantly reduce device size and improve efficiency by utilizing high-frequency transformers and pulse-width modulation (PWM) technology.
How Does a High Frequency Inverter PCB Board Work?
DC input: DC power from batteries or solar panels enters the inverter board.
High-frequency inversion: Power devices (such as IGBTs) switch rapidly under the control of high-frequency PWM signals, converting DC power into high-frequency AC pulses (typically 20kHz-1MHz).
High-frequency transformation: High-frequency AC power is converted (stepped up or down) by a small high-frequency transformer.
Rectification and filtering: The high-frequency AC power output from the transformer is converted to DC power by a rectifier bridge, and then smoothed to a stable DC voltage by a filter circuit.
Power frequency inversion: The filtered DC power is converted to 50/60Hz AC power by an inverter circuit (such as a full-bridge or half-bridge configuration) and output to the load.
Feedback control: A sampling circuit monitors the output voltage and current in real time and adjusts the PWM duty cycle to maintain a stable output.
DC-AC Conversion: Converts DC power from batteries, solar panels, or other sources into 220V/50Hz or 110V/60Hz AC power for use in industrial equipment.
Voltage/Frequency Regulation: Utilizing PWM control technology, the output voltage and frequency are adjustable to meet varying load requirements.
Waveform Optimization: Utilizes sinusoidal or modified sine wave output to reduce harmonic interference and improve power quality.
High-Precision Automated Assembly – We use SMT for Ā±0.02mm placement accuracy, reducing manual errors by 90% and boosting first-pass yield to 99.8% to lower your repair costs.

Conformal coating is a protective transparent layer applied to the surface of a printed circuit board (PCB). It effectively shields electronic components and traces from moisture, dust, and chemical corrosion. The coating conforms precisely to the PCBās shapeāhence the nameāforming a thin, flexible “invisible armor.”
Why Do You Need Conformal Coating?
1. Prevent Moisture-Induced Short Circuits & Leakage
In high-humidity environments, moisture condensation on the PCB can cause leakage current or electrolytic corrosion, leading to system malfunctions or failure.
2. Resist Dust & Contaminants
In industrial, automotive, or kitchen environments, dust, oil, and metal particles can accumulate on the board, creating conductive paths.
3. Enhance Resistance to Salt Spray & Chemicals
Marine and offshore electronics are exposed to salt spray, which can rapidly oxidize solder joints and copper traces
4. Improve Mechanical Stability
Some coatings (e.g., silicone) are elastic, reducing stress on solder joints from vibration.
5. Meet Industry Standards
Sectors like automotive, medical, and military often require compliance with IPC, AEC-Q100, or MIL-STDāconformal coating is a key process.
When Is PCB Conformal Coating Required?
Not every PCB needs a conformal coating, but it becomes crucial when the board faces tough conditions. Think moisture, dust, chemicals, or big temperature swingsāthese can cause corrosion, short circuits, or signal issues. Electronics in cars, airplanes, industrial machines, or outdoor lighting often need this extra layer of protection.
Miniaturized or high-density PCBs also benefit from conformal coating. Tiny spaces between components increase the chance of shorts or solder joint problems. A thin protective layer helps keep the circuits safe and reliable.
Boards that go through frequent heating, cooling, or vibration also get an advantage. The coating helps absorb stress, reducing cracks and extending the boardās lifespan. In short, if your PCB works in a challenging environment, conformal coating is usually a smart choice. Here is a table of what applications require PCB conformal coating.

3. Follow Wiring Conventions
Use straight lines for conductors, with right-angle bends (not rounded). For crossed but unconnected wires, use a “jump” symbol (e.g., a semicircular arc) to avoid confusion. Mark connection points with solid dots to eliminate ambiguity.
4. Provide Complete and Precise Annotations
Label all components with their parameters (e.g., resistance values, capacitance values, part numbers) and identifiers (e.g., R1, C2). Specify power supply voltage polarities and magnitudes. Add explanatory notes for key nodes to ensure the diagram is self-contained and requires no additional clarification.
How to Make an Easy Circuit Diagram?

Thick copper layers improve current handling, enhance mechanical strength, and allow for compact, high-power layouts without compromising reliability.
What is heavy copper PCB?
Heavy copper PCB uses copper conductors that are much thicker than standard PCBs. While standard boards use 1 oz copper (about 35Āµm), heavy copper boards range from 2 oz to 20 oz per square foot. Some extreme designs even go beyond that, which we call extreme copper PCB.
So, why so thick? Because thicker copper carries more current without overheating. It also improves mechanical strength, making the board more robust for harsh environments.
In short, heavy copper PCBs are not ordinary. They are designed for power electronics, automotive, defense, and industrial equipment that demand strength and stability.

Power systems produce heat. A lot of it. If your PCB cannot handle high current, failure is just a matter of time. Thatās why thick copper PCBs are vital.
Hereās why industries love them:
Superior current capacity: Thick copper allows higher amperage without damaging traces.
Better heat dissipation: No more overheating issues in power circuits.
Strong mechanical bonding: Ideal for connectors, heavy components, and thermal sinks.
Design flexibility: Perfect for high-density interconnects and power distribution layers.
Thickness matters. A standard PCB has 1 oz copper (35Āµm). For heavy copper PCBs, the thickness ranges from:
2 oz (70Āµm): Entry-level heavy copper
3 oz to 6 oz (105Āµm to 210Āµm): Common for power electronics
8 oz to 20 oz (280Āµm to 700Āµm): Extreme copper PCB for very high power
The choice depends on current requirements, thermal performance, and mechanical strength. If your design demands high current flow, you need more copper.
What are the common problems in heavy copper PCB design?
Designing a heavy copper PCB is not as simple as adding more copper. It brings challenges:
Uneven Trace Widths: Incorrect design may lead to imbalance.
Plating Difficulties: High copper density affects via plating and reliability.
High Cost: More copper equals higher material and manufacturing cost.
With a professional heavy copper PCB manufacturer like BEST Technology, these challenges are easily solved. Our team uses controlled etching and advanced plating to ensure accuracy and quality.

2. Cut the Copper Tape
Trim the tape to match the broken traceās shape, ensuring itās slightly larger than the damaged zone (covering intact copper on both ends).
The tape width should match the original trace. Length must span the break and overlap adjacent copper (at least 1-2mm).
3. Apply the Copper Tape
Press the tape flat onto the break, ensuring full contact with exposed copper and no air bubbles.
The tape must fully cover the break and extend to nearby pads or vias for reliability.
4. Solder to Secure
Quickly solder the tapeās ends to the PCB copper. Avoid overheating (back adhesive may melt).
Use low-temperature solder. Keep the ironās contact time under 2 seconds to prevent tape detachment.
If repairing a pad, solder the component lead to the tape simultaneously.
5. Trim Excess Tape
Carefully cut or scrape the tape edges to match the original trace width.
Warning: The repair is fragileāavoid excessive force to prevent lifting.
6. Reinforce and Insulate
(Optional) Cover the tape with insulating tape (e.g., Kapton) or apply solder mask to prevent shorts or damage.
For high-stress areas (e.g., PCB edges), reinforce with epoxy (e.g., Araldite).
Application: Where adhesive must not create electrical contact to prevent shorts.
Testing and Verifying Repaired PCB Functionality
1. Visual Check
Look for visible flaws on the repaired PCB, like solder bridges, cold joints, or damaged parts.
Confirm components are placed and oriented correctly as per the design.
2. Continuity Test
Use a multimeter to check electrical continuity between key points, e.g., power/ground traces and component connections.
Ensure no open or short circuits exist.
3. Power-Up Test
Connect PCB to power supply and slowly raise voltage to operating level.
Watch power consumption; check for abnormal current or voltage issues.
4. Function Test
Create and run a full test plan covering all PCB functions.
Use tools like logic analyzers or oscilloscopes to verify digital and analog circuit operation.
Test under different conditions (voltages, frequencies, loads) for stability.
5. Signal Test
For high-speed or sensitive signals, check for crosstalk, reflections, and jitter.
Use TDR or similar methods to analyze signal quality.
6. Thermal Test
Monitor PCB and component temperatures during operation; ensure they’re within limits.
Use thermal cameras or sensors to find hot spots or excessive heat.
7. Environment Test
Put PCB through stress tests like temperature cycling, humidity, and vibration.
Confirm it still works after each test with no degradation.
Long-Term Maintenance Tips for Copper Tape Repairs

Are you always curious these questions about insulated metal substrate PCB:
What is insulated metal substrate? Does it the same as metal core PCB (MCPCB)?
What are the key differences between insulated metal substrate and standard PCB?
Can I use insulated metal substrate in my project? What’s its performance?
As a experienced PCB manufacturer, we can confident to say the insulated metal substrate (IMS) PCB is the same as mcpcb, there is no differences between them. But it is big differ from standard PCB. Actually, IMS PCB offer numerous benefits in high power or heat sensitive projects. In this blog we will introduce what is it, its performance and the differeces with FR4 PCB.
What is an Insulated Metal Substrate (IMS)?
An insulated metal substrate (IMS) is a type of metal core PCB designed for heat-intensive applications. Unlike traditional FR4 boards, IMS uses a metal base layerāusually aluminum or copperācovered with a thin dielectric insulation and a copper circuit layer on top.
The purpose of this design is simple: dissipate heat quickly while keeping the circuit stable. Aluminum IMS boards are most common, offering a balance of cost, strength, and thermal conductivity. Copper IMS is used where performance is critical, especially in high-current applications.
Key characteristics of IMS PCBs include:
High thermal conductivity to transfer heat away from components.
Strong mechanical stability compared to FR4.
Reliable performance in harsh environments.
For industries like LED lighting, automotive electronics, and power supplies, IMS PCBs have become a preferred choice.
What is IMS material for PCB?
The performance and cost of an insulated metal substrate PCB depend heavily on the choice of the base material. Different metals give different levels of thermal conductivity, mechanical strength, and pricing.
1. Copper IMS PCB
Copper has the best thermal conductivity among IMS options. It spreads heat rapidly and is highly stable under load. However, copper is expensive, so it is often reserved for high-power applications such as industrial converters or advanced automotive modules.
2. Aluminum IMS PCB
Aluminum is the most common choice for IMS PCBs. It strikes a balance between cost, weight, and thermal performance. With good heat dissipation and lower price than copper, it has become the preferred material in LED lighting and consumer automotive systems.
3. Iron IMS PCB
Iron-based substrates are rarely used. While they are strong, their lower thermal performance and processing challenges make them less attractive. In most cases, aluminum and copper dominate the IMS market.
What is a Traditional PCB?
A traditional PCB typically refers to a board made with FR4 substrate. FR-4 is a code for a fire-resistant material grade. It represents a material specification where the resin material must be able to extinguish itself when exposed to a burning condition. It is not a material name but a material grade. Most consumer electronics use FR4 PCBs because they are affordable and easy to manufacture.
The construction includes:
Fiberglass base (FR4) for insulation and strength.
Copper foil laminated on one or both sides.
Solder mask and silkscreen for protection and labeling.
FR4 PCBs work well in devices that do not generate extreme heat. They are versatile and suitable for phones, laptops, IoT devices, wearables, and household appliances.
What is the Difference Between Insulated Metal Substrate and PCB?
The key differences between ims pcb and traditional PCB is the base material, IMS pcb uses metal core as the base substrate while traditional PCB uses fiberglass epoxy. Due to the differences base materials used, their performance, price and applications are different accordingly. Here we listing a detailed table for your reference:
Feature
Traditional PCB (FR4)
Insulated Metal Substrate (IMS)
Base Material
Fiberglass epoxy (FR4)
Metal base (aluminum or copper)
Thermal Conductivity
Low (~0.3 W/mK)
High (2ā10 W/mK dielectric + metal base can reach up to 400 W/mk)
Heat Management
Needs extra cooling (heat sinks, fans)
Built-in heat spreading through metal layer
Mechanical Strength
Rigid but less durable under vibration
Strong, resists shock and vibration
Flexibility
Can be rigid, flex, or rigid-flex
Mostly rigid only
Applications
Consumer electronics, IoT, computers
LED lighting, automotive, power modules
Cost
Low, highly economical for mass production
Higher, due to materials and processing
Why is IMS Better for Heat Dissipation Compared to PCB?
As we all know, heat is the biggest enemy of electronic components. If heat builds up, components degrade, solder joints crack, and lifespan shortens. Standard FR4 struggles to move heat away, leading to performance issues in high-power systems.
An IMS PCB solves this by using a metal base that acts like a built-in heat sink. The dielectric layer transfers heat from components directly to the metal, which spreads it out quickly. This keeps the board and devices cooler and improves the overall reliability.
This is why IMS PCBs are widely used in LED lighting, where heat directly impacts brightness and lifespan. Similarly, automotive systems like motor controllers and power converters use IMS to handle constant high currents.
Which Applications Do We Use IMS vs Standard PCB?
Each type of board has its own application areas.
IMS PCB applications
LED lighting systems
Automotive electronics (engine control units, sensors, chargers)
Power modules and converters
Industrial motor drives
Telecom base stations
FR4 PCB applications
Consumer electronics (phones, tablets, laptops)
IoT devices and smart wearables
Household appliances
Audio and multimedia systems
Office electronics
The decision depends on the heat level, power density, and cost balance.
Cost Differences Between IMS and PCB
IMS PCBs are more expensive than standard FR-4 boards due to their raw materials and processing steps. Aluminum-based IMS typically costs $0.12ā$0.25 per cmĀ², while FR-4 falls around $0.05ā$0.10 per cmĀ². Extra copper thickness, dielectric layers, and specialized drilling add further expense.
Yet, the higher upfront cost can translate into system savings. In LED lighting, automotive, and power modules, IMS often reduces the need for heat sinks or cooling parts. Studies show a 15ā20% drop in overall system cost when FR-4 is replaced with IMS, thanks to better thermal control and longer product life.
Design Consideration of Insulated Metal Substrate PCB
Designing an Insulated Metal Substrate (IMS) PCB is more than just replacing FR4 with a metal base. The entire design strategy changes because thermal performance becomes the top priority. Several aspects need careful thought:
1. Dielectric Layer Thickness and Thermal Conductivity
The dielectric is the heart of an IMS PCB. Its job is to provide electrical insulation while transferring heat from the copper layer to the metal base.
Typical FR4 dielectric has thermal conductivity of 0.3ā0.5 W/mK.
IMS dielectrics range from 2 to 10 W/mK, depending on material choice.
Thickness is usually 50ā150 Ī¼m. Thinner layers transfer heat better but risk breakdown if not well controlled.
For normal LED boards, a 75 Ī¼m dielectric with 1-2 W/mK conductivity is often a balance between cost and reliability.
2. Copper Thickness and Trace Design
Current capacity is vital. Wider traces reduce resistance and heat buildup.
Standard FR4 PCBs often use 1 oz (35 Ī¼m) copper.
IMS boards commonly use 2ā3 oz (70ā105 Ī¼m) copper to carry higher currents.
IPC-2221 guidelines suggest that a 2 oz copper trace at 10 mm width can handle around 20ā25 A continuously, which fits the demands of power devices.
3. Component Placement and Thermal Management
Hot components, such as MOSFETs, LEDs, or regulators, should be placed directly over areas where heat can spread into the metal base efficiently. Grouping high-power parts together without proper spacing often leads to localized hot spots.
Simulation tools (like ANSYS or thermal CAD software) are often used to map temperature rise. Data shows that placing components 5 mm apart can reduce local heat rise by 8ā12Ā°C compared to tightly packed layouts.
4. Board Thickness and Mechanical Strength
IMS boards are stiffer than FR4 due to the metal layer.
Common thickness: 0.8ā3.2 mm.
For automotive PCBs exposed to vibration, a 1.6 mm aluminum base is typical for balancing rigidity and weight.
Designers should consider mounting holes and mechanical supports early to avoid stress cracking during assembly.
5. Surface Finishes and Soldering
Surface finishes like ENIG, ENEPIG, OSP or HASL are commonly applied. However, IMS boards undergo more thermal cycling during soldering, so ENIG is often preferred for reliability.
Factors Affect the Failure of Insulated Metal Substrate PCB
Even with proper design, IMS PCBs can fail if certain risks are not controlled. Failures usually stem from thermal, mechanical, or environmental stresses. Letās examine the main causes, with supporting data:
1. Thermal Stress and Cycling
IMS PCBs are exposed to wide temperature swings, especially in LED lighting (-40Ā°C to +120Ā°C) or automotive control units (-55Ā°C to +150Ā°C). In additional, a thinner dielectric layer (<75 Ī¼m) is more likely to fail under repeated expansion and contraction. So, using high Tg dielectrics (Tg ā„ 170Ā°C) and flexible solder materials reduces the chance of cracks.
2. Dielectric Breakdown
The dielectric layer separates copper circuitry from the conductive metal base. If the insulation fails, short circuits occur.
Standard IMS dielectric breakdown voltage: 2ā6 kV/mm.
If the dielectric is too thin or contaminated during manufacturing, breakdown may occur earlier, especially in high-voltage power supplies.
3. Corrosion and Moisture Ingress
If the protective coating or solder mask is not properly applied, moisture, chemicals, or salts can corrode the copper traces or the aluminum base. There is no doubt that unprotected copper can corrode in under 72 hours in a salt spray environment (5% NaCl). Therefore, applying ENIG or OSP surface finishes greatly reduces corrosion risk.
4. Mechanical Stress and Vibration
IMS boards are less flexible than FR4, which means they can crack under excessive bending or vibration.
In automotive vibration testing (10ā2,000 Hz sweep, 20 g), poor mounting caused delamination in 5ā10% of samples after 50 hours.
Poor drilling, lamination errors, or uneven dielectric spreading can lead to early failures. For example:
Misaligned lamination can create voids, which increase heat resistance and raise local temperatures by 10ā15Ā°C.
Improper drilling of vias in IMS can leave burrs or microcracks, leading to premature electrical failure.
Best Technology has more than 19 years in IMS PCB manufacturing. It cannot be denied that we had ever faced such problems and solved them finally, then we have much experiences to solve them and mature skills to avoid such defectives.
Insulated Metal Substrates Market
The insulated metal substrates market has grown rapidly with the demand for efficient heat management in electronics. Several sectors drive this expansion:
LED Lighting: As LEDs move into general lighting, street lamps, and automotive headlights, IMS boards remain essential for heat control.
Electric Vehicles (EVs): Motor controllers, inverters, and battery systems require durable IMS boards to handle high currents.
Industrial Power Systems: Power converters, motor drives, and renewable energy inverters are major adopters.
Telecom: Base stations and 5G equipment rely on IMS to stabilize performance under heavy workloads.
Market reports suggest steady growth in IMS adoption worldwide, especially in Asia-Pacific regions like China and South Korea, where LED and EV industries are booming. Aluminum IMS PCBs dominate due to cost efficiency, but copper IMS is growing in high-performance niches.
How to Choose Between IMS PCB and FR4 PCB?
The choice between IMS PCB and FR-4 PCB depends on performance demands, cost expectations, and application environment. If your design handles high power density or generates significant heatāsuch as in LED lighting, power converters, or automotive control unitsāIMS PCB is usually the better option. Its aluminum or copper base provides strong thermal conductivity, keeping component temperatures 20ā30% lower than FR-4 under the same load.
FR-4 PCB, on the other hand, is more suitable for general-purpose electronics where heat generation is moderate. Devices like consumer gadgets, IoT sensors, and low-power communication modules often prioritize affordability and flexibility in design over extreme thermal performance. FR-4 also supports higher multilayer counts more easily than IMS, which is beneficial for complex circuits with dense routing.
So, in a word:
Choose FR4 PCB if your device is low-power, cost-sensitive, and not heat-intensive.
Choose IMS PCB if your design generates high heat, requires high reliability, or operates in harsh environments.
In practice, many manufacturers use both types in their product lines. Consumer electronics stay with FR4, while lighting and automotive turn to IMS.

How to choose base copper weight for RF board? Letās explore base copper weight options, selection guide, cost optimize solution, recommended supplier for RF board.
Are you troubled with these problems?
Severe signal attenuation?
Uncontrolled temperature rise?
Impedance fluctuations?
Best Technology can provide solutions:
Dynamic copper thickness algorithm reduces skin loss by 40%.
Gradient copper structure reduces hotspot temperature by over 15Ā°C.
Intelligent impedance compensation with a Ā±0.5Ī¼m tolerance ensures 5G+ accuracy.
Base Copper Weight refers to the thickness of the initial copper foil on the PCB substrate (usually measured in ounces per square foot or microns). It directly affects the circuit’s current carrying capacity, signal transmission stability, and thermal management performance. It is a core parameter in PCB design that balances conductivity, heat dissipation requirements, and manufacturing feasibility.
Why Base Copper Weight is Important for RF Boards?
Limitation: high process complexity, increased lamination cost.
How to Choose the Base Copper Weight for RF Boards?
1. Define High-Frequency Requirements & Loss Budget
Evaluate RF circuit loss budget (dB): Based on signal frequency, transmission distance, and acceptable loss, determine the maximum per-unit-length loss.
Copper thickness impact on conductor loss: At high frequencies, the skin effect concentrates current near the surface; thicker copper reduces conductive loss. RF signal layers typically use 0.5-2 oz base copper.
Use 0.5 oz or 1 oz to balance loss and etching precision. Thicker copper (ā„2 oz) complicates etching and limits minimum trace/space.
Power/ground planes
Prioritize 2 oz to 6+ oz to minimize resistance and thermal stress.
Internal layers:
Signal layers: 0.5 oz for trace width <0.127 mm to enhance etching accuracy.
Plane layers: 1 oz for cost efficiency; 2 oz requires ā„10 mil spacing and adds ~20% cost.
5. Account for Manufacturing Constraints
Minimum trace/space rules:
1 oz boards: Outer layers ā„5 mil (2-layer) or ā„3.5 mil (4/6-layer).
2 oz boards: All layers ā„8 mil.
Lamination structure:
4-layer PCBs: Internal copper optionsā0.5 oz, 1 oz, or 2 oz (ā„1.6 mm thickness required for 2 oz).
Plating impact: Final copper thickness (e.g., after ENIG) must include design margins.
6. Cost-Material Optimization
Standard weights (0.5/1/2 oz) are cost-effective; custom thicknesses require special processes and increase costs.
High-frequency laminates: e.g., Rogers RO4003C often pairs with 0.5 oz (ā17 Ī¼m) base copper for stable dielectric properties.
Cost-sensitive designs: Use FR-4 with 1 oz copper; for >5 GHz, combine optimized copper with RF laminates.
How Does Base Copper Weight Impact RF Board Production Cost?
1. Material Cost & Copper Thickness
Impact: Each 1 oz (ā35Ī¼m) copper increase raises raw material cost by 30-50%; >3 oz requires special rolling, costing exponentially more.
Solution: Prioritize standard weights (0.5/1/2 oz) for scalability; use “localized thick copper” (e.g., 2 oz only for power planes) to avoid full-board waste.
Example: 5G base stations reduce cost 15-20% by pairing 1 oz signal layers with 2 oz power planes.
2. Etching Complexity Control
Impact: Thick copper (ā„2 oz) causes undercut, extending etching time 20-40% and increasing depreciation costs.
Solution: Adopt Semi-Additive Process (SAP) or optimized etchants (e.g., acidic cupric chloride); design with 10% width compensation for 2 oz traces to minimize rework.
3. Trace/Space Design Optimization
Impact: 2 oz copper requires ā„8 mil trace/space, limiting density and potentially increasing layer count or expensive processes.
Solution: Use 0.5 oz for signal layers (supports 3.5-5 mil) with HDI microvias; balance with 1 oz for non-critical layers.
Solution: Deploy AOI for real-time etching monitoring; reinforce thin copper with support layers; optimize stack-up to reduce interlayer stress, targeting >95% yield.
7. Supply Chain & Economies of Scale
Impact: Custom weights require premium pricing and longer lead times, increasing inventory/logistics costs.
Solution: Partner with fabricators for pooled standard weight inventory; use panelization for custom orders to share fixed costs; explore cost-effective alternatives like Cu-Al composite foil.
