Laser Trim Inspection

Machine Vision Company LLC developed a system to inspect Laser Trim on ceramic substrates. The specific resistance value of a resistor printed onto a ceramic substrate can be trimmed by laser cutting. By visually inspecting the cuts made by a trimming program, the yield and quality of a production line is increased.
