While organizing an article on the structural analysis of Micro-USB connectors, Workingbear came across an interesting soldering concept that he would like to discuss with everyone.
During the product development and NPI verification phase, RD often comes to me, I am a Manufacturing Process Engineer, with questions about the length of the metal shell soldering pins on Micro-USB connectors. Typically, these pins are only 0.8mm long because the thickness of mobile phone boards is usually around 0.8mm to 1.0mm only. However, our company’s PCBs have a thickness of 1.6mm.
