AI Technical Summary

⚠Technical Problem

In the existing technology, the welding process of miniature externally sealed linear compressors is difficult to operate and is prone to problems such as overlapping welding, excessively high solder joints, short circuits, and high temperature at solder joints leading to damage to the enamel coating of the coil windings.

⚗Method used

A miniature externally sealed linear compressor coil welding wire busbar is adopted, including a base plate and multiple welding pads. The coil winding and the pin are connected through the conductive channel. The welding area is covered with a solder resist cover film. The base plate is made of polyimide and coated with adhesive to achieve single wire welding and avoid overlapping welding and high temperature damage.

🎯Benefits of technology

It reduces the difficulty of operation, improves the consistency and stability of welding, prevents short circuits, ensures welding reliability and high temperature resistance, and avoids short circuits caused by contact between the weld point and the compressor housing.
