1   Copper residue, no fault
2   Short circuit conductor / land for soldering
3   Copper residue, no fault
4   Copper residue (spacing too small)
pcb manufacturing Our PCBs and inner layers for multilayers undergo an automated visual inspection depending on the composition.

This inspection device covers the entire PCB and examines it for:
• Short circuits
• Restrictions
• Breaks
• Foreign particles

This inspection system locates any discrepancies in the completed PCB and shows it to the operator on a screen. He then decides whether this is an actual defect or just a false. With this method, each PCB can be inspected 100 %.
