Printed Circuit Board Assembly

Printed Circuit Board Assembly (PCBA) is an essential procedure for manufacturing electronic devices in which various electronic components are connected to bare PCBs. As both PCBs and their components become increasingly smaller and more complex, the accuracy of the inspection process is critical to electronic components’ function and longevity.

As a leading vision expert, Basler has many years of experience equipping optical inspection systems across the PCBA industry. That is why our vision products are trusted by manufacturers to deliver reliable vision inspection for high quality PCBs.


3D- Solder Paste Inspection (3D-SPI) analyzes printed circuit boards for solder paste defects by monitoring paste alignment and volume.​

PCBA Applications

Inspection and quality control are critical for PCBA manufacturing. These processes significantly lower the probability of defects for every unique test state the PCB undergoes. This reduces unnecessarily rejected PCBs, improving first pass yield (FPY) while saving time and expense.
