Industry Knowledge
Tab 01 Why are most PCBs green?
Green solder mask is cost-effective, environmentally friendly, and has mature manufacturing processes. Other colors are typically used for prototype identification or special applications.
Tab 02 What's the difference between ENIG (Gold Plating) and HASL (Tin Spray)?
ENIG provides a flatter surface for high-density pads, while HASL is more cost-effective but less smooth, making it suitable for standard boards.
Tab 03 What are blind and buried vias?
Blind vias connect outer to inner layers, while buried vias are entirely within inner layers. Both require HDI technology and enable high-density routing.
