【摘要】：摄像头模组主要由镜头、滤色片、音圈马达、马达驱动、图像传感器等部件构成。图像传感器和音圈马达驱动都是CMOS半导体器件,对ESD(Electro-Static Discharge)非常敏感。本文的主要内容包括以下几个方面:(1)摄像头模组的ESD保护设计,主要从结构设计和电子设计两个方面来阐述,结构设计时主要对ESD敏感区的保护;电子设计时主要是对CMOS芯片的接口引脚进行保护。(2)人体模型的研究,主要讨论HBM(Human Body Model)的仿真模型的创建。(3)静电释放的波形仿真和实验,主要讨论测试环境的建立,并对比目标和实际波形。
[Abstract]:Camera module mainly consists of lens, filter, voice coil motor, motor drive, image sensor and other components.Image sensors and voice coil motor drivers are CMOS semiconductor devices that are very sensitive to ESD(Electro-Static charges.The main content of this paper includes the following aspects: 1) the ESD protection design of camera module, mainly from two aspects of structure design and electronic design, the protection of sensitive area of ESD in the structure design;The main purpose of electronic design is to protect the interface pin of CMOS chip. The human body model is studied. The creation of simulation model of HBM(Human Body Model is mainly discussed. The waveform simulation and experiment of electrostatic release are discussed, and the establishment of test environment is mainly discussed.And compare the target with the actual waveform.
