ABSTRACT:
A manufacturing method for rectifying diodes, wherein, a plurality of upper and lower pins are combined with a plurality of electronic chips to form a coarse blank. And then they are processed to form shaped insulating layers by molding. Each insulating layer is processed to have superficial coarseness having micro-protuberances thereon; the areas on both the lateral sides of the insulating layer are applied with electric conductive layer. The electric conductive layer is combined with the insulating layer; they are equidistantly cut with a knife into shaped rectifying diodes. The shaped rectifying diodes each is further electrically plated with a further layer of electric conductive material on both sides of the electric conductive layer to form a harder protection layer, and then finished rectifying diodes are obtained. The upper and lower pins are in the form of thin sheets, plus the small chips, the shaped rectifying diodes have small volumes. The rectifying diodes are made by mass production, hence work efficiency can be increased, while cost of production can be reduced.
