Abstract
PURPOSE:To manufacture a photocoupler stably and at a low cost by a method wherein it is sealed with a light-transmitting resin by a casting operation in order to prevent a thin burr from being produced caused by leakage of the resin from a plastic case. CONSTITUTION:Lead frames 3 where a semiconductor light-emitting device 1 and a semiconductor photodetector 2 are installed are built in a plastic case 4; a stopper 5 for resin outflow prevention use is installed into a groove of the case into which the lead frames 3 are put. A resin 6 is injected into the plastic case 4 in such a way that it covers the lead frames 3. After that, the resin 6 is hardened at a high temperature. In addition, if the stopper 5 for resin outflow prevention use and the plastic case 4 are removed, the internal resin is formed. After that, if the resin 6 is covered with a light-shielding resin, a photocoupler is completed. A methylpentane polymer or the like to be used to manufacture a lamp can be used as a material for the plastic case. In addition, as the resin for a casting operation, a material where a filler and silicone rubber for deterioration prevention use of a light-emitting device are mixed with a resin to be used to manufacture the lamp can be used.
