What are the best test methods for PCB printed circuit boards?

To test PCB printed circuit boards, the manufacturer's help may be needed. There are two types of bare board PCB testing: fixture testing and flying probe testing.

Fixture test

This involves the development of a fixture that contains multiple pins that match the number of nets on the line. This means you will have two nail clippers, press the PCB printed circuit board from the top and bottom, hundreds of probes and

PCB test point connection. This is a very fast test method, but it is also an expensive method. If any changes are made to the board after the tool is produced, it must be remade.

Flying probe test

This uses two or more probes to test all the networks on the PCB printed circuit board. The probe moves along the XY axis according to the layout programmed on the test panel. There is no need to develop a fixture for flying probe testing, which makes it a cheaper option. However, the flying probe test is relatively slow.

Fixture test and flying probe test are both ways to avoid the trouble of ignoring manufacturing problems in PCB printed circuit boards. If you want to produce a small amount of PCB, flying probe test is a better choice. The cost of flying probe test is calculated for each PCB. If the number is small, it is more economical. However, if you want to manufacture hundreds of PCBs, you need to choose fixture testing. Most of the cost comes from the fixture setup.
