The solder joint infrared radiation detecting system was developed in SMT laser micro soldering, and a numerical model of infrared sensing of the micro joint was put forward. The calculated results show that the melting and wetting of the solder were recognized by the infrared radiation signal, therefore the signal can be used to control the joint quality simultaneously in laser micro soldering.
