Function Test

Shenzhen Grande Electronic offers Function Test (FCT) with its turn-key assembly services. Function Test usually is performed after the circuit boards are assembled and AOI & visual inspections are finished. Early testing allows us to find and correct component failures, assembly defects or potential design issues at an early stage and make troubleshooting as quick as possible. Finally, customers can deliver a perfect product to their clients in a short time frame. Function Test is done mainly to avoid assembly issues including shorts, opens, missing components or the installation of incorrect parts.

 
Function Test engineers typically use a computer that is connected to test points or a test-probe point in order to perform FCT. We determine if the boards pass or fail based on whether or not the test results meet the specified requirements by operating the software or firmware.

 
Function Test is enabled by testing software, often referred to as firmware, and testing instruments such as digital multimeters, input/output PCBs, communication ports. Automated computer-based Function Test (FCT) is accomplished by assembly line operators who utilize testing software that interfaces with external instruments to monitor the devices under test.
                                      

We would like to work together with you to implement Function Test. Our testing engineer will preview your requirements such as test scope and test instruction, design the test jig if necessary, set up the instruments, prepare the test report form and design testing workflow.

At Grande, we are equipped with an adjustable DC power supply, a 200MHz digital oscilloscope, a signal generator, a LRC multi-meter and a universal programmer. This covers most embedded system testing. The test results can be either collected by a computer or recorded manually. If the board does not pass the testing, a troubleshooting program will be launched to find the root cause of the failure. A Design For Assembly (DFA) form will be issued by our process engineer and an 8D quality assurance report will be created by our quality engineer. The DFA report will be sent to the customer as a design reference. The latter will become our quality improvement guideline.
