PCB Test Fixture/ Jig
FCT(Functional Test) Fixture
Functional tests are designed to assure that circuitry functions within specifications. Testing is usually done “at speed” through DUT connectors and/or BON fixture. The number of pogo pins typically needed for a functional test fixture is significantly less than an ICT fixture.
Functional test (FCT) Advantages:
-Identifying functional defects within a printed circuit board assembly
-Assessing functionality while applying marginal power supply voltage and/or current
-Appraising functionality of DUT while applying a range of input stimuli amplitudes or currents
-Determining DUT power consumption during operation
-Uncovering problems with analog circuitry such as:
- Wrong oscillator frequency
- -Analog signal clipping/distortion
- Amplifier gain or bandwidth issues
- Drive currents of power output circuits
- Potentiometer adjustment issues
-Revealing issues with digital circuitry such as:
-Signal timing (design or component related)
-Communications problems (Ethernet, DeviceNet, Serial, etc)
