电路板和元器件在焊接过程中产生翘曲，由于应力变形而产生虚焊、短路等缺陷。翘曲往往是由于电路板的上下部分温度不平衡造成的。对大的PCB,由于板自 身重量下坠也会产生翘曲。普通的PBGA器件距离印刷电路板约0.5mm,如果电路板上器件较大，随着线路板降温后恢复正常形状，焊点将长时间处于应力作 用之下，如果器件抬高0.1mm就足以导致虚焊开路。

PCB stands for Printed Circuit Board. It is a flat board made of non-conductive material like fiberglass or plastic, with conductive tracks or pathways etched or printed onto its surface. These conductive tracks are used to connect various electronic components together, such as resistors, capacitors, transistors, and integrated circuits, to form a functioning electronic circuit. PCBs are widely used in electronic devices and are an essential part of modern electronics manufacturing.
