PCB cleaning diagnostic system

26 June 2019 Test & Measurement

The Verinas system from PBT Works is a dedicated piece of AOI (automatic optical inspection) equipment for evaluating remaining flux residues on PBT glass test boards.

The system can be used by electronics manufacturers to perform statistical cleaning process control over their printed circuit board (PCB) assembly processes, as well as verification of the cleaning process after changes, and cleaning process capability studies.

The transparent glass base allows for precise measurement of the cleaning progress under components, and the situation after cleaning is scanned through the glass. Precise colour filters are applied to determine the boundary between cleaned and not yet cleaned areas under chips. Areas with remaining flux residues are measured by dedicated software, and a test report is automatically generated using 400 values of flux residues under each chip.
