The metal template used in SMT patch processing, also known as the slip plate, steel plate, and steel mesh, is used to quantify solder paste and is a key fixture to ensure the printing quality of SMT patch solder paste. Stencil is to etch a hollow out on a piece of metal chemically, or use a laser engraving machine to engrave the leak hole, and use an aluminum alloy frame to stretch the edge of metal plates into a appropriate size.
SMT patch PCB assembly is crucial to today's electronics manufacturing process. Now more and more circuit boards are produced and used widely.The manufacturing of SMT PCB assembly contains many complicated processes, it will be very challenging to construct effectively.
Every step in the SMT processing shows the importance of high manufacturing technology. Various problems may arise in different steps and stages. In multiple processes, challenges for example the quality control and the reduction of the product’s performance under high temperature occured oftenly. In this way, the whole process of production may require more time and results in the delay of the delivery. This may be risky because your reliability will be affected. Obviously, choosing the right manufacturer is particularly important.
