Problems solved by technology

The flexible circuit board is fixed to the housing by welding, and the assembly process includes processes such as fitting, soldering, and notch glue. The assembly process is complicated and requires processes such as hot spots and pressure maintaining; due to the small size of the flexible circuit board, The assembly accuracy is poor, and it is necessary to apply notch glue to the outlet groove after assembly. If the notch glue is not applied in place, there will be a risk of air leakage in the outlet groove; at the same time, the price of the flexible circuit board is relatively expensive
