HDI PCB

High density interconnect PCBs are a way to leave more space on a printed circuit board to increase efficiency and speed up transfer speeds. It’s relatively easy for most aggressive companies using printed circuit boards to understand how this will benefit them. High Density Interconnect HDI PCBs represent one of the fastest growing segments of the…

PCB inner layer production process fully explained

1. Process classification Divided into single-sided, double-sided, and multilayer boards by the number of PCB layers, these three board processes are not quite the same. Single-sided and double-sided panels do not have an internal flow, it is basically an open-drill-follow-up process; Multi-layer boards will have an inner flow 1) Single panel process flow Cutting and…
