What is HDI for PCB?
HDI stands for High Density Interconnect. It’s a type of printed circuit board that has a higher wiring density per unit area than standard boards. In simple terms, HDI PCBs are more compact, but they carry more connections. This is made possible with microvias, blind vias, and fine traces.
Compared to regular boards, HDI PCBs support tighter designs, faster signal transmission, and lower power usage. These qualities are essential in smartphones, medical equipment, automotive electronics, and wearable tech. If space is limited, HDI is the answer.
The HDI PCB definition includes features like:
- Laser-drilled microvias
- Multiple layers
- Fine line width and spacing
- Higher pin count in smaller space
Because of these features, HDI is becoming standard in advanced electronics.
What is the difference between HDI PCB and standard PCB?
- Via Types: HDI boards use microvias, blind vias, and buried vias. Standard boards use only through-hole vias.
- Layer Count: HDI can have more layers in a thinner stack-up.
- Design Complexity: HDI supports finer pitch components and smaller trace widths.
- Performance: Better signal integrity, lower crosstalk, and reduced EMI.
- Applications: HDI is used in compact devices. Standard PCBs suit less demanding products.
In short, HDI vs PCB boils down to density, complexity, and function.
What is the HDI PCB manufacturing process?
The HDI PCB manufacturing process involves advanced steps. It requires more precision than regular PCB production. Here’s how it works:
- Material Preparation: Choose high-quality laminate suitable for fine lines.
- Laser Drilling: Use lasers to drill microvias with precise control.
- Copper Plating: Deposit copper inside vias and on the surface.
- Imaging: Apply photoresist and use UV light to define circuit patterns.
- Etching: Remove unwanted copper, leaving behind trace paths.
- Lamination: Stack multiple layers with insulating layers between.
- Testing: Conduct electrical tests to ensure quality and reliability.
The HDI PCB fabrication process demands cleanrooms, skilled technicians, and controlled environments. This is why choosing the right HDI PCB manufacturer is vital. Best Technology is an original HDI PCB factory, with a monthly capability of up to 260,000 square feet (28,900 square meters), and more than 1,000 different boards will be completed.
