Understanding PCB Board Deformation and Prevention** PCB boards often deform during processing, especially in reflow soldering, leading to issues like misalignment and component damage. To prevent this, maintaining strict deformation limits and ensuring even distribution of materials and structures in the PCB are crucial for high-precision assembly.
PCB deformation can result from complex thermal and mechanical stresses during manufacturing, causing issues like inaccurate component placement, difficulty in lead trimming, and improper fit in enclosures, which is exacerbated by uneven material properties, manufacturing processes, and storage conditions.
PCB deformation during processing is caused by thermal and mechanical stresses, which can be mitigated through careful design, proper handling, and specific post-processing steps like stress relief, drying, and controlled cooling.
