Understanding the Effects of Moisture on PCBs Moisture can have several detrimental effects on PCBs: Corrosion: When exposed to moisture, the metal components on a PCB can corrode, leading to reduced conductivity and potential short circuits. Delamination: Moisture can cause the layers of a PCB to separate, resulting in delamination and compromised structural integrity. Electromigration: High humidity levels can accelerate electromigration, causing the movement of metal ions and potentially leading to open circuits. Fungal Growth: Read more…

Understanding the Fundamentals of Wave Soldering Before delving into the best long-term practices for wave soldering, it is crucial to understand the fundamentals of this process. Wave soldering involves the following key steps: PCB Preparation: The PCB is designed, fabricated, and populated with components on the top side, leaving the bottom side exposed for soldering. Flux Application: A thin layer of flux is applied to the bottom side of the PCB to remove oxides, prevent Read more…
