Functional Test Fixtures and In-Circuit Testing for Industry

Printed circuit board (PCB) test fixtures are vital tools used during the PCB manufacturing process to confirm that fabricated boards meet design specifications.

They provide an interface between test equipment and a unit under test (UUT) to enable efficient and accurate testing.

As the manufacturing process improves and changes are made in the way that interface test adapters and components are used,

the options for testing will continue to evolve. While a majority of the focus used to be on In-Circuit testing as the preferred method,

today more attention is now given to functional test fixtures for things like printed circuit board (PCB) assemblies.

In-Circuit Test Fixtures

In-Circuit Testing is excellent for locating manufacturing defects, such as open connections, wrong or missing components, and solder shorts. It can also perform tests without power being applied to the device under testing to avoid causing damage to the assembly.

Functional Test Fixtures

Functional test typically applies full operational power to a loaded printed circuit board in order to determine if the PCBA performs functions as designed. This type of test often involves custom built test equipment and custom test fixturing. PTI supports all forms of functional test strategies.
