For each product we construct a pinbed analyses tool. Through numerous pins that contact the PCB backside all contacts are being measured and tested.
Defect components or malicious soldering will be discovered through this test
First there is the Optical Inspection where it is made sure that all components are rightly place. This can either be a visual inspection or automated through a so called AOI scanner. AOI refers to Automated Optical Inspection.
Thirdly we perform a Functional Test by which we make sure the print functions as it should. This can be done via connectors or via a pin bed device which makes contact to dedicated contact points on the backside of the PCB.
