A PCB-Tester is a base setup that is used to test a PCB.

The tool is used by OEM's either in new production and/or repair.

The PCB-Tester project implements such a PCB-Tester in open source.

It consists out of the following components:

• Rack ➜ 19", holds the 'instruments' of choice when implementing a PCB-tester for a specific PCB.
• Housing ➜ The 'box' that holds the PCB-Tester (1x PCB-Tester-Board and 0 or more PCB-Relay-Boards)
• Fixture ➜ Mounted on the Housing, and implements the "moving parts".
• JIG ➜ Not a part of this project, belongs to a specific implementation. (iow: 'needle-bed')
• The Software framework.

The whole thing looks like this:
