Abstract: In the process of the integrated circuit's lead trimming&forming, the abnormal things such as tiebar fracture, crack of plastic seal and breakage of lead are appeared. In the production of circuit products, if these anomalies can not be found in time, it will result in mass scrapping of the product and damage to the related T/F equipment. This paper introduces how to use photoelectric sensor and detection pin system to detect and protect the possible anomalies in the trimming and formming of the lead of the integrated circuit.
