DMC’s PCB functional test solution integrates National Instruments test and measurement technology with a flexible fixture design to ensure the system (and investment) is ready to adapt as new requirements are identified.<\/p>\n\n\n\n

The gauge cluster PCB functional test system (pictured on the right) highlights DMC\u2019s ability to deliver fully integrated turnkey test applications. DMC takes pride in assembling strategic, skilled, multi-disciplinary teams that combine DMC’s vast engineering and software development capabilities.<\/p>\n\n\n\n

The test system provides complete product test and verification capabilities. It can download firmware and preform pre-power up, open\/short verification, communication bus, and power consumption testing. At the heart of the test system lies an NI PXI chassis and multiple measurement devices, including a dual-channel power supply, source measurement unit, CAN communication cards, and switch matrix.<\/p>\n<\/div>\n\n\n\n

DMC developed a LabVIEW application that allows flexible test sequencing across different test stands. In addition, we integrated generic PC peripherals with the LabVIEW application to ensure that high-level functionality of common interfaces (Ethernet, USB, and Serial) was verified. Pairing precision instruments with everyday IO in a custom test sequence allowed for end-to-end product testing and was made possible by the NI TestStand development platform.<\/p>\n\n\n\n

The test system is also fully integrated with a Microsoft SQL server database to ensure compliance with modern production requirements. Database-level traceability, especially in the automotive industry, allows manufacturers to confidently and securely store production data with ease of recall for internal reporting or external audit. SQL offers an extensive toolchain for custom data analysis and process performance analysis to ensure the system continues to run reliably throughout its lifecycle.<\/p>\n<\/div>\n\n\n\n
