Multilayer Pcb, 34 Layers, Back Drilling, Laser Blind Holes

YMS PCB from Shenzhen China offer this 34 layers Printed Circuit Board, with the back drill and blind holes, back drill hole size is 0.5mm. The blind hole is 0.1mm drilled by laser machine, stack up is 1+32+1, 1 step HDI board. It’s used in semiconductor test equipment, so the min warp & twist is only 0.5%, much less than the IPC-II standard (0.75%). Board thickness is 5.0mm with 0.3mm holes, the aspect ratio is 17:1, need to do special control in PTH process.
