Film Inspection Machine
Phototool is the critical carrier for PCB graphic transfer. Any defects on the phototool—scratches, pinholes, dust, or notches—will transfer to the copper surface during exposure, causing open circuits or short circuits. The phototool inspection machine detects these defects through high-precision optical scanning, ensuring every production-grade phototool is flawless. This serves as the first quality checkpoint before graphic transfer.
