Abstract:
1. A method for producing an electronic part package in which electrode terminals of electronic part to be mounted are electrically connected to posts as external connecting terminals by electrically conductive patterns, the method comprising the steps of: forming a first insulating layer having a thickness same as a thickness of the electronic part on a seed layer made of metal and formed on one surface side of a support plate through a peeling off layer, forming, on the first insulating layer, a first recessed part with a size in which the electronic part is inserted to be positioned and the seed layer is exposed on a bottom surface and second recessed parts in which the seed layer is exposed on bottom surfaces and the posts are formed; filling the second recessed parts with an electrically conductive material to form the posts, inserting the electronic part into the first recessed part, forming the electrically conductive patterns that electrically connect the electrode terminals of the electronic part to the posts; forming a second insulating layer that covers the electrically conductive patterns to form the electronic part package in the one surface side of the support plate through the peeling off layer, separating the seed layer from the support plate by the peeling off layer; and removing the seed layer and the first insulating layer adhering to the electronic part package.
