Problems solved by technology

[0002] With the rapid progress of microwave and millimeter wave technology, the structure of microwave and millimeter wave products is constantly developing towards complexity. The complexity of the structure has greatly increased the difficulty of PCB assembly of microwave components.
The traditional rigid crimping technology is mainly based on processing a profiling pressing block on the printed board, and applying a force to the printed board through the pressing block to press the printed board to complete the welding of the printed board. This rigid crimping technology Because it is rigid, there are high requirements for the flatness of the printed board welding surface, the flatness of the microwave component structure surface welded with the printed board, and the flatness of the pressure block pressing surface. Any of the three Failure to meet the requirements will affect the assembly reliability of microwave components
