Abstract:
1. A method for manufacturing a photocoupler, comprising: mounting light emitting devices and light receiving devices on a lead frame sheet including: positioning the lead frame sheet with respect to a die by cutting off a first set of column portions from the linking portion and inserting a first pilot pin on the die into the second pilot hole; positioning the first set of column portions with respect to the die such that the light emitting devices and the light receiving devices are in a facing arrangement with each other by inserting a second pilot pin formed on the die into the first pilot hole and stacking the light emitting side coupling bars and the light receiving side coupling bars; connecting the light emitting side coupling bars and the light receiving side coupling bars to each other on the die; forming a resin body so as to cover a pair of the light emitting device and the light receiving device; and cutting off the light emitting side lead frame portion from the light emitting column portion and cutting off the light receiving side lead frame portion from the light receiving column portion.
