Description
Technical Field
[0001] This utility model belongs to the field of connector technology, specifically a surface mount board connector for SMT. Background Technology
[0002] In electronics manufacturing, the connection method between connectors and PCB boards directly affects equipment lifespan and signal integrity. Statistics show that 30% of early failures are due to defects in the connection process. Connector World will conduct an in-depth analysis of five mainstream technologies—SMT mounting, through-hole soldering, crimping, screw fixing, and spring contacts—and combine them with the needs of scenarios such as automotive ECUs and industrial controllers to provide selection criteria from the dimensions of process cost, vibration resistance level, and high-frequency adaptability, helping engineers avoid design risks.
[0003] The SMT pins of existing SMT mounting connectors are generally bent by an automatic machine using a metal strip. The SMT pins bent by the automatic machine have a thin structure, and the connection between them and the socket body is extremely unstable. Furthermore, it is difficult to control the flatness consistency of the SMT pins bent by the automatic machine, which makes it easy for poor soldering to occur during the soldering process.
