Pcb Functional Testing

Functional testing involves a lot of variability making it very complex.

Pcb functional testing. Let s distinguish between pcb functional testing services and other pcb testing then get into the specifics and advantages of each. 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. We provide pcba functional testing service with our turnkey assembly services after circuit boards are assembled spi aoi and visual inspection are finished. Functional testers typically interface to the pcb under test via its edge connector or a test probe point.

Functional pcb printed circuit board testing is performed at the end of the manufacturing process to ensure that the manufactured part will not fail immediately or have a shortened service life. Functional testing is enabled by testing software often referred to as firmware and testing instruments such as digital multimeters input output pcbs communication ports. Variabilities include how much of the pcb is going to be tested what type of inputs or stimuli is needed what are the desired results and what are the testing parameters. Functional testing s faults functional testing is certainly not a perfect testing solution.

The most common form of functional test known as hot mock up simply verifies that the pcb is functioning properly. Pcb function testing is a crucial stage prior to the integration of these boards into complete systems. Automated computer based functional testing fct is accomplished by assembly line operators who utilize testing software that interfaces with external instruments to monitor the devices under test. 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.

This testing simulates the final electrical environment in which the pcb will be used. Fct stands for functional testing which is a crucial and final pcb assembly manufacturing step prior to integration of the pcb assemblies into complete systems.
