摘要:
A self supported underfill film (18) adhesively bonds surface mount integrated circuit packages (14) to a printed circuit board (10). The printed circuit board has conductive traces (12) and exposed conductive pads (13) on the surface. A film adhesive is strategically positioned on the printed circuit board near the conductive pads, and the surface mount integrated circuit package is then placed on the board so that the conductive pads (16) on the package align with the conductive pads on the board. The film adhesive softens when the package is soldered to the board, and the film ultimately serves as an underfill to increase the mechanical integrity of the solder joints.

自支撑底部填充膜(18)将表面贴装集成电路封装(14)粘合地粘合到印刷电路板(10)上。 印刷电路板在表面上具有导电迹线(12)和暴露的导电焊盘(13)。 薄膜粘合剂在导电焊盘附近在印刷电路板上有策略地定位,然后将表面贴装集成电路封装放置在板上,使得封装上的导电焊盘(16)与板上的导电焊盘对准。 当封装焊接到板上时,膜粘合剂软化,并且膜最终用作底部填充物以增加焊点的机械完整性。
