How to improve the pass rate of SMT patch processing?

SMT chip processing has an important indicator for processing quality evaluation, that is, the straight-through rate. In the patch processing. SMT process pass rate refers to the proportion of one-time qualification from production to the last process.

PCB assembly manufacturers introduce the basic PCB design process in detail

PCB design is a very detailed work, so the design should be very careful and patient, fully considering various factors, including production PCB assembly processing, post-maintenance convenience and other issues. In addition, developing some good working

SMT patch processing requirements for flux

In the welding process of SMT patch processing, the substance that can purify the welding metal and welding surface and help welding is called flux, referred to as flux.
