Soldering Details
Module Mounting
The production technical difficulty of this product is mainly the mounting of modules. It is necessary to ensure that the mounting height of modules is consistent . Furthermore, this module is very easy to be mountedwith false soldering.
Main chip mounting
The number of pins is large and the spacing is small. The surface mounting process should be very high. At the same time, pay attention to the cleaning of PCBs board.
