Module mounting

 

 

The production technical difficulty of this PCBs 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

 

 

The  design and mounting of this Laser marking circuit board are very difficult, because the PCB size is small, but the design is very complex, there are many kinds of materials, and there is a large module, which reflects a high design level and mounting technology
