It enables fast and reliable functional testing of up to four circuit boards simultaneously, is specifically designed for use with LED curing devices, and meets the validation requirements for medical technology. ## Challenges and Concept ![](https://mcd.site team.de/wp-content/uploads/2026/07/FCT-dentistry-device-pcbs_mcd-002-scaled.png) ![](https://mcd.site team.de/wp-content/uploads/2026/06/Group_30131.svg) The test system was developed to perform functional testing of printed circuit boards in LED curing lamps used in dental technology. Up to four circuit boards can be tested simultaneously in an adapter with a mobile ULC rack, enabling extremely short cycle times of up to two sets of circuit boards per minute. Markings on the adapter allow for quick identification of the LED driver boards and ensure reliable process control. The semi-automatic test sequence assists the operator in performing and confirming the test steps via touchscreen or barcode scanner. ## Scope of Testing and Functionality ![](https://mcd.site team.de/wp-content/uploads/2026/06/Group_30131.svg) The system meets the validation requirements set forth in medical device guidelines and has been successfully qualified for use in medical applications. The test station performs fully automated current and voltage measurements under various load conditions. In addition, LED light sources (2×470 nm and 1×410 nm), the controller board’s operating functions, as well as indicator LEDs, buzzers, and pushbuttons are tested. Faulty results are documented individually and protected from being overwritten, ensuring complete traceability. ## Test Methods Used and Challenges ![](https://mcd.site team.de/wp-content/uploads/2026/06/Group_30132.svg) Control is handled by the MIO1616 unit in combination with the TestManager CE test software. The system is supplemented by a multimeter module and a touchscreen monitor for user interaction. All inspection data is centrally recorded and documented, ensuring tamper-proof evaluation. The clear assignment of defects to individual inspection points enables a precise analysis of PCB quality and increases process reliability in mass production. ## FREQUENTLY ASKED QUESTIONS ### FAQS What is the FCT testing system used for?
