Choose the Right Test Head
The eC-test-mate has 3 different ergonomic Test Heads, each with different functionality.
· T1 is used for generic applications
· T2 to test communication interfaces
· T3 to provide additional measurement functions when required for either application.
Depending on your circuit design and your test requirements you can combine these to create a complete suite of functional tests. Each Test Head has a unique keying pin, so it can only lock into its own footprint.
Test Heads
The Test Heads are connected with three micro USB cables to the Docking Station. The Test Heads need it sit in their correct position (color coded). When performed correctly, the LEDs on the Test Heads will light up green.
The Test Head fixation method
eC-test-mate is provided with an innovative fixation method to establish a perfect connection between the Test pins (about 21 on every Test Head) and the footprint on the PCB to be tested. Every Test Head has a unique keying pin to lock into its unique corresponding footprint on the PCB. This fixation method is also used to connect a Test Head into its corresponding opening (in the Self-test PCB) in the Docking Station.
All LEDs on the Test Heads and Docking Station are green when your eC-test-mate station is ready for use.
