Functional Testing

For its turn-key PCB assembly services, Bittele Electronics includes Functional Testing (FCT). Functional testing is typically accomplished after PCB assembly and AOI & Visual inspections are completed. Functional testing is done early in the assembly process to discover and repair component breakdowns, assembly faults, or design problems, as well as ensuring troubleshooting can be accomplished rapidly. It is performed primarily to prevent assembly problems such as short circuits, opens, omitted component, or insertion of the wrong components. Lastly, functional testing ensures customers provide a reliable PCB to their clients before deadlines.

Functional testers usually operate computers that are connected to test points on the PCB or utilize a test-probe point to do the FCT. The PCBs pass or fail the function test based on achieving the detailed requirements when the software or firmware is run.

Functional testing is performed via testing software, usually called firmware, and test equipment, including digital multimeters, input/output PCBs, and communication ports. Automated computer-based Functional Testing (FCT) is performed by PCB assembly associates who use testing software that is connected to external equipment that monitors the devices under test (DUT).

We would enjoy working with you to launch your functional testing. Our test engineers will first examine your requirements like test scope and test instructions, and then design the test platform, assemble the test instruments, write the test report form, and finally design the test workflow.

Bittele possesses an adjustable DC power supply, a 200MHz digital oscilloscope, a signal generator, an LCR multimeter, and a universal programmer. This equipment is usually what is needed to perform most embedded system testing. Test results can be gathered electronically via computer or documented by hand. If a PCB fails testing, troubleshooting will commence to determine the source of the fault. A Design for Assembly (DFA) form will be generated by Bittele's process engineer. Our quality engineer will generate an 8D quality assurance report. The DFA report will be transmitted to the client as a design reference, which will also be included as a quality improvement guideline.
