HDI PCBs (High Density Interconnect PCBs) are widely used in compact, high-performance electronic products.
However, HDI manufacturing is not just about adding more layers — the real challenge lies in the process control.
Key Challenges in HDI PCB Manufacturing
1. Laser Microvia Precision
HDI PCBs rely on laser-drilled microvias, typically around 0.10 mm in diameter.
Precise control of laser energy and depth is critical. Any deviation can cause poor via quality or misalignment.
2. Microvia Copper Plating Reliability
Unlike through holes, microvias are shallow and narrow, making uniform copper plating difficult.
Insufficient plating at the via bottom can lead to long-term reliability issues.
3. Layer Alignment in Multiple Laminations
HDI boards often require multiple lamination cycles.
Accurate layer-to-layer alignment is essential to prevent via offset and pad damage.
4. Yield and Cost Control
HDI processes are complex and material-intensive.
Without stable process control, yields drop and costs rise quickly.
