SMT: Technical Points for Mounting Flexible PCB

There are many differences between the flexible PCB SMT process and the SMT solution of the traditional rigid PCB. If you want to do the SMT process of the flexible PCB, the most important thing is positioning, because the hardness of the flexible PCB is not enough, it is softer, and if the special carrier is not used, it cannot be fixed and transmitted, and the basic SMT processes such as printing, patch, and furnaces cannot be completed. The key points of pre-processing, fixing, printing, patch, reflux welding, testing, and division plates of flexible PCB in the production of SMT production are specified as below.



1. Flexible PCB pretreatment

The flexible PCB is softer, and it is generally not a vacuum packaging when it leaves the factory. It is easy to absorb the water in the atmosphere during the transportation and storage procedures. You need to prepare pre-baking treatment before the SMT patch process and slowly discharge the water, otherwise, under the impact of reflux welding at high temperatures, the water absorbed by the FPC quickly vaporizes into steam, which can easily lead to poor flexible PCB layer departure and foaming.
