Description

Technical Field

[0002] In many industrial production scenarios, traditional manual soldering methods are no longer sufficient to meet the demands for high-efficiency, high-quality production. However, existing automated soldering technologies still have many shortcomings when applied to PIN soldering in automotive connectors.
