The ever advancing electronics industry requires an increasing need for electronic component testing (IC testing) and component verification.

The methods we use most are:

Flying Probe (basically an automated way of contacting pins and checking if the resistance meets expected values). This also comes relatively cheap since the programs can be created from netlists which have to be specified by the customer.

ICT&FCT

Boundary Scan

The Flying Probe can mainly contact test points or larger points such as resistors, ... if there is no available point to touch it on the PCBA, the Flying Probe is of no use. To test Inter-IC connections we mainly rely on Boundary Scan Tests if the Controller supports these. But they have their limits as well. Also, programs can be "written" automatically but need to be adapted.

In-Circuit-Tests

This is probably the most extensive test method we use (and also the most expensive). Basically we build an adapter which will host the DUT and contacts the various testpoints. Using integrated Boundary Scan techniques and stimulating digital and analog signals nearly every mode of testing is possible. E.g. it is also possible to boot the board to some bootloader and execute tests available in the bootloader, test Ethernet connections, test USB connections, ... No need to say that this comes at a cost.
