HDI is an English abbreviation of High Density Interconnector. High -density interconnection (HDI) manufacturing is the fastest development area in the printed circuit board industry. From the first 32 -bit computer launched by HP in 1985, it has now adopted a large customer server with 36 sequential layers of multi -layer printed boards and stacking micro -perforated. HDI/miniature perforated technology is undoubtedly the future PCB architecture. Large ASICs and FPGAs with smaller parts of the device, I/O tube foot and embedded non -passive devices have a shorter and higher frequency and higher frequencies. They all require smaller PCB feature size, which promotes the right right HDI/micro -perforated strong demand. HDI process
