EМ-5434M High density integration PCB stepper


EМ-5434M High density integration PCB stepper

EM-5434M stepper is designed to enable a lithography process in the production of PCBs (IC Substrate) for flip-chip packaging (BGA/CSP). 

The universality of the tool lies in capability to work with thick photoresist (50µm) and to control the resist side wall angle.
