<p><P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a shield case which is low-priced and improved in productivity while improving bonding between an opening part and a ground electrode by accurately performing opening processing, through a simple process, on an insulating coating film on the shield case located at a position bonded with the ground electrode on a substrate, the shield case being small-sized and reduced in weight and including the insulating coating film on a mounting face and inside thereof. <P>SOLUTION: A manufacturing method of a shield case assembly includes a step (A) of manufacturing the shield case assembly by arranging a number of shield cases in a chocolate bar shape comprised of (m) pieces of longitudinal shield cases×(n) piece of lateral shield cases ((m), (n) independently represents an integer of 2 or more, respectively), a step (B) of forming an insulating coating film by applying an insulating resin composition to a mounting face and the inside of the shield case assembly opposed to a substrate, a step (C) forming an opening part by irradiating, with laser light, the insulating coating film at a position bonded with a ground electrode of the substrate, and a step (D) of cutting the shield case assembly into individual pieces. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
