Abstract: Standard PCB design and mounting processes can adversely influence MEMS inertial sensors.This application note contains guidelines for the layout, soldering, and mounting of MEMS inertialsensors in LGA packages in order to reduce stresses and improve functionality.
表面贴片胶(SMA,surface mount adhesives)用于波峰焊接和回流焊接,以保持组件在印刷电路板(PCB)上的位置,确保在装配线上传送过程中组件不会丢失。PCB装配中使用的大多数表面贴片胶(SMA)都是环氧树脂(epoxies),虽然还有聚丙烯(acrylics)用于特殊的用途。在高速滴胶系统引入和电子工业掌握如何处理货架寿命相对较短的产品 ...
