Pcb Functional Test

This testing simulates the final electrical environment in which the pcb will be used. 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. As part of our iso9001 2008 quality management system we carry out three stages of pcb inspection of all assemblies prior to pcb testing and running functional test before out of our factory every piece of board need to do strict testing.

Pcb functional test systems examine the whole assembly not just its components.

Pcb functional test. It then replicates the pcb s final electrical environment. In some ways functional circuit tests are similar to icts in that they use connectors to attach to the board. For example if a pcb is the end product going into a slot inside of a computer then during functional testing the slot that it s actually going into when it s placed into service will be simulated. Pcb function testing is a crucial stage prior to the integration of these boards into complete systems.

In some cases functional testing eliminates the need of performing system tests that can be expensive. With this method of testing one can test 50 to 100 of the product being shipped. The most common form of functional test known as hot mock up simply verifies that the pcb is functioning properly. Functional testers usually do so by interfacing with the pcb via its test probe points or edge connectors and testing to certify that the pcb functions according to design specifications.

To test a pcb s functionality a functional tester interfaces to the pcb via its edge connector or a test probe point. Functional testing helps improve the quality of the final product by making it error free and robust. In contrast to existing functional testing equipment designed for one particular pcb only the proposed platform is universal and can be easily reconfigured and reprogrammed to test different pcbs. This helps save on financial resources as well as time.

This kind of circuit board testing simulates the environment in which the actual assembly will be required to perform. Functional testers typically interface to the pcb under test via its edge connector or a test probe point.
