The guidline of PCB Flying Probe Test
The aim of PCB Flying Probe Test
You may know PCB flying probe test during the manufacturing process.
But the aim of the PCB flying probe test was not known by normal people.
In PCB manufacturing area, the PCB flying probe test ensures PCB board meets the requirement.
This means that high fault coverage with accuracy in a short time.
By the way, the short time compares traditional PCB test method.
If you have read our article about the mould PCB test, you may know it fast than flying probe test method.
PCB flying probe test V.S. ICT
The PCB flying probe test usually uses for prototype PCB verification.
If you have learned the prototype PCB verification method, you will find that PCB flying probe test is really cost effective than other method.
Some small PCB factory may ask you to choose an ICT test method.
The reason is due to the ICT PCB test method requires costly test fixtures.
This point is very different between PCB flying probe test and ICT.
PCB flying probe test provides a simple way to correct prototype PCBs
If you have read our article about The Electrical test process of rigid PCB, you may find PCB flying probe test also a important test method for prototype PCBs.
Because most of them can eliminate enormous cost programming time.
Then allow design changes with simple test program changes.
In other words, the PCB flying probe test provides a simple way to correct prototype PCBs.
It’s really can save most prototype PCB test cost.
The working theory of PCB Flying Probe Test
The PCB flying probe test allows connection to test points.
Most of PCB flying probe test machine has a camera function.
This means that you can through a camera to visual inspection during PCB flying probe testing.
Then is electronic performance testing.
PCB flying probe test machine can capable of doing some power up testing.
The flying probe pins can inject signals at certain points on the testing PCBs.
Then detecting the output at other locations.
This is the most simple working theory of the PCB flying probe test.
