Since the 1960s, Surface Mount Technology (SMT) has slowly become the go-to for putting together electronic parts. It’s brought a lot of changes to how we make electronic products, especially when it comes to making things more efficient, cheaper, and smaller. Surface mount technology has its pros and cons. In...

When choosing a surface treatment, the gold plating process is usually a good choice. Because of the stability of gold, it can effectively resist corrosion and oxidation and provide long-term reliable protection for PCBs. In practice, engineers are usually faced with two choices: ENIG and hard gold. Although both...
