In-Depth Comparison and Analysis of PCB Surface Treatment Processes

1. The Core Role of Surface Treatment Processes First, it is important to understand why surface treatment is necessary: Preventing Copper Oxidation: Bare copper is highly susceptible to oxidation in the air, and the resulting copper oxide can severely damage solderability. Providing a Solderable Layer: It provides a good soldering surface for the connection between … Read more

Exploring the Shelf Life of PCBs: Definitions, Influencing Factors, and Scientific Evaluation Methods

In the electronics manufacturing industry, Printed Circuit Boards (PCBs) serve as the substrate for electronic components and the hub for electrical connections. Their quality and reliability directly determine the performance and lifespan of the final electronic products. However, a crucial issue that is often overlooked is that PCBs are not used immediately after production; they … Read more
