The demand for compact-sized and lightweight electronic devices has increased over the years. As a result, many components of these devices have become smaller, and printed circuit boards are one of them. These components feature high component density, and organizing all components on the PCB is one of the significant challenges faced by PCB designers. PCB warpage is one of the biggest concerns addressed by them. A warpage in PCB assembly or warping is a bent that occurs due to unbearable stress on a printed circuit board. This affects the overall functioning of a PCB by impacting the quality of paste printing and solder joints. Although experienced PCB designers follow the best practices of PCB design and assembly, warpage may still be a reality. If you have observed issues like open joints, stretched joints, head and pillow joints, solder bridges, etc., in your printed circuit boards, then it is probably due to the PCB warpage. What causes this warpage? Can it be prevented? Read this post to know the answers.
What Causes Warpage in PCB Assembly?
Warpage in PCB assembly occurs due to the following reasons:
Design Changes Done to Prevent Warpage in PCB Assembly
The causes that may lead to PCB warping cannot be eliminated from the PCB manufacturing process. However, warpage in PCB assembly can be prevented by implementing changes in the PCB design and assembly phase.
The above pointers will help PCB designers to minimize the effect of warpage during the PCB assembly. In addition, sourcing warpage-inspected PCBs from a trusted and reliable manufacturer can help you manufacture the best quality electronics that will lead to your business standards in the global market.
