Flying probe testing for PCB assembly use test probes that fly, as the name suggests. The test probes move from one test point to another to detect defects in a board. Sierra Circuits uses Seica Spa Pilot V8 machines for flying probe testing.
The flying probe tester can test for shorts, opens, and component values such as resistance, capacitance, and inductance.
Flying probe testing does not require custom fixtures, hence called a fixtureless in-circuit test when used on an assembled board. This makes it highly cost-effective for prototype and low to mid-volume production.
We start by generating a test program which is loaded into the flying probe tester. The circuit board assembly to be tested is then placed on a conveyor belt so that it can move inside the testing area where the probes are present.
When our engineering team runs the test program, the probes will contact the component pads, test pads, and the unmasked vias as per the pre-loaded test program. The tester will apply electrical test signals and power to the probe points and make measurements.
These measurements will be processed inside the tester to find if the circuit portion between the probes is delivering the expected results within the specified tolerances. This is how we detect the defective units.
The flying probe tester hardware includes signal generators, DC and AC power supplies, and various sensors. These provide signals required to excite the PCB nodes and make measurements on the component nodes and interconnections and the assembled circuit.
The hardware also includes a camera that automatically inspects component polarity.

Flying probe testing requires ODB++ files.
We recommend flying probe testing to customers developing very dense and complex boards. This is our preferred method to test the quality of your PCBA and ensure we can reduce your time to market as much as possible.
Not only is flying probe testing cost-effective for small to medium production runs, it also helps R&D teams to go to market faster by ensuring the viability of their electronics right out of PCB assembly.
As opposed to in-circuit testing that uses pogo pins, a flying probe tester is equipped with fine probe points capable of accessing much smaller pads.
Because the probe movements and landing positions are generated by software, we can easily reprogram them to apply different testing strategies.
By accessing component pins directly through automated probing without requiring specifically built test points, flying probe testing for PCB assembly offers better test coverage than ICT.
