摘要
芯片封装与测试工艺中,需对芯片电容进行测量完成合格性筛选,国内厂家目前多采用人工测试或购买国外的昂贵的电容测试设备。从应用角度出发,设计了批量自动化电容测量设备。该设备采用多路位置传感器与步进电机组成闭环控制系统,并加入安全控制与告警机制。试验表明该系统可实现芯片卷带自动、安全、可靠测试。
The chip packaging and testing process requires that the capacitance of the chip is tested and qualified,and the domestic manufacturers currently uses manual testing or foreign expensive capacitance testing equipment. This paper designs a batch automatic capacitance measuring equipment from the perspective of application. The device uses multi-position sensor and stepper motor to form a closed-loop control system,and the security control and alarm mechanism are added. The results show that the chip coil can be tested automatically,safely and reliably.
