What is PCB warpage?

septembre 18, 2025by kkpcba-辛迪0

What is PCB Warpage? PCB warpage refers to the unwanted bending, twisting, or deformation of a printed circuit board from its intended flat shape. Ideally, a PCB should maintain a flat and stable surface throughout fabrication, assembly, and operation. However, differences in material properties, thermal expansion, copper distribution, and manufacturing processes can cause the PCB...
