What is a PCB test fixture?How do you test for PCB?What material is used in PCB test fixtures?

Описание: Functional testing, also known as FCT testing, is the last manufacturing step of PCB creation. Essentially, functional testing makes sure the PCB works correctly. Functional tests examine the entire assembly rather than individual components.

HOW PCB FUNCTIONAL TESTING WORKS
PCB functional test systems examine the whole assembly, not just its components. This kind of circuit board testing simulates the environment in which the actual assembly will be required to perform. With functional testing, it’s possible to test up to 100% of the products before an ECM ships them to an original equipment manufacturer (OEM, AKA you).

What Is PCB Test Jig and Fixture
It's always good to know and understand the common terms used in the electronics hardware testing business. Generally speaking, a test fixture or test jig is the component containing the bed of nails used for testing the PCB or assembled product. Some PCB test fixtures can be used for edge connector functional testing.



These PCB testing fixtures can either be mechanically or pneumatically operated. The mechanical PCB test fixtures require the user to manually close the test fixture's top hat on the PCB, holding it into place. This activates the bed of nails, pressing it against the PCB. Due to the mechanism involved, the mechanical test fixtures are cheaper in comparison to the pneumatic test fixtures.



Specialized and custom designed PCB testing jigs and fixtures are used to test PCB. Testing point is identified and probed to identify the input to be given and output to be measured. A PCB testing jig can be identified as a device or machinery that holds a piece of machine work which nowadays comprised of much electronic intelligence and guides the tools operating on it. It should not be confused with PCB testing fixtures which are used to keep the object firmly in place. However, in PCB testing both the terms test jigs and test fixtures are interchangeably used as a electro-mechanical solution to test the printed circuit boards or PCBs. Custom-made PCB test jigs and test fixtures are made as per the application of the board to test its testing points.

A test jig is essentially a contraption that allows you to test many components of a board all at once.

There are a lot of things to consider when creating a test jig, ranging from test coverage to operator fatigue, and of course throughput and reliability. In some cases, a product designer may spend even more time designing a test jig than they spend designing the product itself!

The impact that a well-designed test jig can have on manufacturing efficiency is huge. These are extremely important for large scale manufacturing, as reputable factories will test 100% of every product shipped. It is easy to lose sight of the potential pitfalls of hardware manufacturing and the magnification of those issues at scale; if you can cut a product's testing time from 4 minutes to 1 minute the time savings will pay off exponentially as thousands of units are tested
