How do you troubleshoot common defects and failures of SMT and through hole assemblies?
Soldering is one of the most common and essential techniques in electronics manufacturing. It involves joining metal components with a molten alloy, called solder, to create electrical connections. There are two main types of soldering methods: surface mount technology (SMT) and through hole (TH). Both have their advantages and disadvantages, and both can result in defects and failures if not done properly. In this article, we will compare SMT and TH, and explain how to troubleshoot some of the most common issues that can affect them.
