HDl PCB
May 10,2023
What is a high-density interconnect (HDl) PCB circuit board? High Density Interconnect (HDI) PCB circuit board is a circuit board with relatively high line distribution density using microblind and buried via technology. The most effective way to increase board density is to reduce the number of vias and precisely place blind and buried vias to meet this requirement, resulting in an HDI board. Thi...

Half Hole PCB
May 03,2023
What is a Half Hole PCB? Half-hole PCB means that one drill hole (drill, gong groove) is drilled, and then the second drill, shape process, and finally half of the metallized hole (groove) is reserved. Module PCBs are basically designed with half holes, mainly for the convenience of welding, small module area, and many functional requirements. The usual half hole is to design a hole on the edge of...
