PCB warping is a common issue that affects the performance, assembly, and reliability of electronic devices. Warped PCBs can lead to misalignment, poor soldering, and signal integrity issues. To produce a high-quality PCB, manufacturers must understand the causes of warping and apply effective solutions.What Causes PCB Warping?Several factors contribute to PCB warping, including:1. Uneven Copper DistributionWhen copper is unevenly distributed, different areas of the board expand at varying rates during PCB manufacturing. This imbalance creates mechanical stress, leading to board deformation.2. Poor PCB Material SelectionThe choice of PCB material is crucial in preventing warping. Materials with high moisture absorption or low thermal stability can expand unpredictably, causing structural instability.3. Incorrect Lamination ProcessDuring lamination, multiple layers are pressed together under heat and pressure. If the process lacks precise control, internal stresses can develop, leading ...
