Method of manufacturing photo couplers

摘要

A method of manufacturing photo couplers is provided. At first, a receiver lead-frame array is cut from a lead-frame matrix having a transmitter lead-frame array and the receiver lead-frame array. Then, the receiver lead-frame array is overturned and placed on the lead-frame matrix to allow light-receiver elements on the receiver lead-frame array to face light-emitting elements on the transmitter lead-frame array of the lead-frame matrix. Finally, the receiver lead-frame array and the lead-frame matrix are connected.
