碩士 === 明新科技大學 === 工業工程與管理系碩士班 === 106 === PCB (Printed Circuit Board) or PWB (Printed wire board) is the mother of electronic products, is an important electronic components, is the support of electronic components, is the electronic components of the circuit connection provider. PCB has been developed for decades. In recent years, due to increasingly thin and light end products, the electronic products have changed from the standardized specifications of the past to the form of flexible custom-made specifications. In the face of the "few and varied" trend of scientific and technological products in the future, the reliability of PCB (or trust, Reliability) test is highly valued. PCB products for environmental reliability testing, based on the PCB's temperature cycling test (Temperature Cycling Test, hereinafter referred to as TCT) as the most common and important test methods. Using the phenomenon of CTE mismatch with different thermal expansion coefficients among different materials, we can generate breakthroughs in holes and delaminated products (Delamination) during long-term high temperature and low temperature cycling, so as to help find the quality risk of products. This test method is highly effective for multilayer products and high-density interconnect (HDI) products. It can also be used to verify and improve the strength of Lamination Bond, the quality of electroplating and the stability of process. Expect to perform product reliability verification through this TCT test, repay R & D departments to improve the reliability of Wireless Router and win orders through customer verification.
