PCB warpage refers to the out-of-plane deformation of printed circuit boards that occurs after they are removed from the pressing fixture or specific environment, which does not meet design requirements. It can generally be subdivided into two forms: ✒︎ Bowing Deformation resembling a bowl or arch bridge, where the four corners of the PCB are … Read more
📌 Problem Overview BGA components are prone to deformation during the reflow soldering process due to high thermal stress. This deformation can lead to poor contact between BGA solder balls and pads, resulting in cold solder joints, short circuits, or solder joint fractures due to stress concentration in later usage. The following table summarizes the … Read more
PCB warpage is very common during the production and processing of PCBs. Once it occurs, it can seriously affect the performance and reliability of the product, such as poor soldering and component damage. How can we effectively control PCB warpage? First, we need to understand 1. Standards for PCB Warpage According to IPC standards, the … Read more
