8 Layer TG170 EING PCB

Storm circuit has been producing multilayer pcbs for over 10years. Over the years, we have seen all types of multilayer constructions from various industries, answered all types of multilayer questions, and solved all types of problems with multilayer pcbs.the 8 layer pcb is easy to us.this  job the trace and space are 3.5mil,the drill holes just have 0.15mm.we finish them just cost 3 workdays via our urgent service.
