One of the two most common methods of attaching electronic components to PCBs is the through-hole or through-hole process. This technology is older than SMT, and for many years, it was the standard technology for PCB assembly. When surface mount technology became popular in the 1980s, many people thought it would make through-hole PCB assembly obsolete. However, through-hole technology has several advantages that make it still a preferred choice for certain applications.
In recent years, electronic products have become increasingly complex and integrated into people’s daily lives. However, there are still two popular methods for soldering electronic components together to build circuits:
Surface Mount Technology (SMT) for PCB Assembly
Through-Hole (PTH) PCB Assembly
