Patent ID: 7888189

Claim:
A method for manufacturing an electronic device comprising a plurality of lead frames individually supporting an electronic component surrounded by a casing, the method comprising steps of: charging a first resin into each casing on a base on which the plurality of lead frames are formed by: using a mask having through-holes in positions corresponding to regions surrounded by the casings; positioning the mask in such a manner that the through-holes of the mask are positioned to correspond to the regions surrounded by the casings; moving a first squeegee along a surface of the mask to charge the first resin into the regions via the through-holes of the mask; and moving a second squeegee along the surface of the mask while pressing the second squeegee against the surface to remove any excess portion of the first resin, thereby making a surface of the first resin flat; and cutting the base to separate the lead frames into individual lead frames.
