Function Test

Function Test is our electronic function testing service that validates PCB assemblies, functional requirements, and reliability standards before release. It includes in-circuit testing with bed-of-nails fixtures, flying probe testing, automated functional testing (FCT) using custom test jigs, boundary scanning, firmware flashing and verification, burn-in testing, thermal cycling, and system-level performance validation—ensuring 100% compliance with design and quality expectations. Our advanced function test stations feature high-speed I/O interfaces, data gathering in real-time, automated test sequencing, reporting on passes and fails, and full traceability via barcode and serial number tracking. This enables us to create test programs quickly, and generate precise failure diagnostics to deliver ≥99.5% test coverage. Ready for reliable, production-proven function testing? Let's verify performance with confidence.

Manufacturing Metrics

All of our services have different metrics. We've aimed to unify and better present the capabilities of our manufacturing services through a standardized approach.

Function Test

Manual Testing

Manually, we test devices that come in small batch sizes or are not yet adapted to robotic systems. We either use in-house designed test equipment or equipment that the partners provide when testing PCBAs. The devices are designed to hold the device in a fixed position and provide the necessary electrical connections to test the various components on the board.

Robot Assisted Testing

Testing is one of the most crucial and time-consuming electronics manufacturing steps. To make this process more efficient and fast, we use testing robots. Systems are equipped with two robotic hands and can serve 16-24 testing fixtures. The robotic cell is separated into two sides, and each of them can test one specific product. The firmware is flashed before testing. The operation sequence is as follows: an operator loads the robot with a stack of trays with untested devices. These trays are specially designed for robotic operations. As soon as the tray enters the robot, scanners verify that the right tray has been fed for testing. The SCARA robot then retrieves the device from the tray and puts it on a stable base, enabling a stable and accurate PCBA position to minimize the impact of handling errors. The PCB board is taken from the base by the assistant robotic hand and brought to the testing fixture. It completes the testing cycle and logs all necessary testing data into our production management system. When testing is complete, the robot places the device back into the steady base, where SCARA picks it up again and places it either in the pass or fail section according to the testing data. The combination of both robots creates synergy, enabling the electronics testing process to be faster and more precise.
