PCB Inspection with Higher Speed and Precision
To prevent process errors, increase the yield and reduce the costs in the manufacturing of assembled printed circuit boards (PCB), Delvitech from Switzerland offers automatic optical inspection (AOI). The core element of these systems is an optical head consisting of five cameras and various side-mounted illuminations.
Delvitech chose two different programmable frame grabbers, both compatible with diverse cameras and lighting as well as the software. The upper camera, four side cameras and the lighting are synchronized by the microEnable 5 VCX-QP CoaXPress frame grabber, while the up to four side cameras are triggered by two Camera Link frame grabbers microEnable 5 VCL. For the side cameras, four monochrome Camera Link Basler Ace CMOS with 4 MP resolution and 180 frames per second are now used.
The components can be flexibly exchanged and scaled regardless of the camera model and interface, and the system can be easily adapted to new customer requirements thanks to the accompanying applet
