手机摄像头模组生产工艺的SMT流程及SMT应用分析

摘要

随着通信技术的不断扩延，手机已成为人们生活、工作、学习、娱乐不可或缺的工具。而手机摄像头模组是手机中非常重要的组件之一，其品质的好坏直接影响手机整体品质的高低。因此在手机摄像头模组生产的过程中每一步都是要严格把关的，不能有丝毫的懈怠。在手机摄像头模组中，FPC软电路板是决定手机照相生成图片的关键组件之一，因此它的生产工艺及质量好坏显得尤为重要。

基于此，首先简单介绍了手机摄像头模组原理以及SMT技术在手机摄像头模组生产工艺中的应用,着重阐述了手机摄像头模组FPC软电路板的改良设计和SMT生产工艺流程及产品质量分析。根据手机摄像头模组FPC软电路板的具体要求，合理进行SMT技术指标优化，分析研究了手机摄像头模组再流焊SMT焊接温度分布曲线。针对FPC软电路板产品设置了AIO（automatic optical inspection）检测及ICT在线测试方法。

Mobile phone camera module production technology of SMT processes and SMT application

ABSTRACT

Summary as communication technologies continues expansion, mobile phone has become the people's life, work, learn, play an indispensable tool. Mobile phone camera module is one of the very important components in the mobile phone, its quality directly affect the overall level of quality phones. In the mobile phone camera module production at every step in the process is to strictly, there can be no slack. Mobile phone camera module in the FPC flexible circuit board is to determine the key components of the camera phone picture, therefore its production process and the quality is particularly important. Based on this, the first simply introduced the mobile phone camera module principle and SMT technology and its application in mobile phone camera module production, focusing on mobile phone camera module is described FPC flexible circuit board design and analysis of SMT production process and product quality. According to mobile phone camera module FPC flexible circuit board requirements, reasonable SMT technical specifications, analysis of mobile phone camera module for reflow SMT soldering temperature distribution curves.FPC flexible circuit board set AIO products (automatic optical inspection) test online test methods and ICT.
