Ceramic PCB Manufacturing Process
Understanding the ceramic PCB manufacturing process helps you choose the right partner. At Best Technology, the DBC (Direct Bonded Copper) production process includes the following steps:
- IQC Inspection: Incoming ceramic substrates are carefully checked to ensure they meet specifications.
- Laser Drilling: Precise laser machines drill necessary vias and holes.
- Vacuum Sputtering (PVD): A thin metal layer is applied to the ceramic surface using Physical Vapor Deposition.
- Flash Plating: A light coating is applied for better conductivity.
- Pattern Transfer: The design pattern is transferred onto the board using photoresist.
- Pattern Plating: Conductive layers are built up in the patterned areas.
- Brushing and Polishing: Surface is brushed and polished for smoothness.
- Photoresist Removal: Residual photoresist is stripped from the surface.
- Etching and Titanium Removal: Unwanted copper is etched off, and any titanium barrier layers are removed.
- Electrical Testing: Boards are tested for shorts, opens, and continuity.
- Solder Mask: A protective layer is added over areas not meant for soldering.
- Pre-Cutting: For silver surface finishes, pre-cutting comes before plating; for gold, it usually happens after.
- Surface Treatment: Final surface finish is applied (silver or gold).
- Incoming Inspection: Boards are inspected again before moving to final stages.
- FQC and FQA: Final Quality Control and Final Quality Assurance ensure boards meet customer standards.
- Packing: Boards are cleaned, labeled, and packed for safe delivery.
This well-controlled flow helps reduce defects and maintain high reliability, making Chinese ceramic PCBs a trusted option worldwide.
Key Materials Used by China Ceramic PCB Manufacturers in Production
Materials decide how well a ceramic PCB performs. Here are the most used ones:
- Aluminum Oxide (Al2O3): Common, cost-effective, and offers good insulation.
- Aluminum Nitride (AlN): Preferred for its excellent thermal conductivity.
- Silicon Nitride: Less common but offers high mechanical strength and resistance to thermal shock.
Chinese manufacturers often maintain a stable supply of high-purity materials. This allows consistent performance in each batch. Some even offer custom material blends depending on your needs. As a leading China PCB manufacturer, Best Technology enables full customization across all our ceramic PCB offerings.ā In reference to Best Technology’s ceramic substrate specifications, the standard thicknesses of Alumina (AlāOā) substratesā include 0.15/0.25/0.38/0.5/0.635/0.8/1.0/1.2/1.5/2.0 mm. Aluminum Nitride (AlN) substratesā are available in 0.15/0.25/0.38/0.5/0.635/0.8/1.0/1.5 mm thicknesses. Non-standard ceramic substrate types require customization. For tailored thickness specifications, kindly consult our account management team or sales engineering specialists to discuss project-specific parameters.

How Do China Ceramic PCB Manufacturers Ensure High Thermal Conductivity?
High thermal conductivity is key for ceramic PCBs. Chinese manufacturers make this happen through several strategies:
- Use of AlN substrates: These offer better heat transfer than traditional materials.
- Thicker metal layers: Copper or silver layers are optimized for heat spreading.
- Advanced firing techniques: This reduces internal voids and boosts thermal flow.
These steps help their ceramic PCBs survive in high-power LED lighting and RF power devices.
What Certifications Do Top China Ceramic PCB Manufacturers Hold?
Certifications add credibility. Most leading China ceramic PCB manufacturers meet strict global standards. Look for these:
