Enhancing PCB quality control with Sensofar's 3D metrology solutions

Optimize PCBs analysis to copper circuits, vias, and pads.

Producing a printed circuit board (PCB) involves a series of critical steps that directly influence its overall performance. Both the surface finish and key dimensions of a PCB are crucial in determining its functionality. For this reason, the PCB industry demands highly controlled fabrication environments, including clean rooms and highly precise deposition and assembly techniques.

During production, PCBs are evaluated using various methods, including X-ray analysis, 2D defect inspection, SEM imaging, and 3D optical metrology. With over two decades of expertise in 3D optical metrology, Sensofar is dedicated to delivering advanced solutions for PCB quality assurance.
