Method for manufacturing electronic component module
A method for manufacturing an electronic component module is performed such that a shield layer can be formed as a thin film and an electronic component can be effectively shielded. A collective substrate including a plurality of electronic component modules including a plurality of electronic components is batch-sealed with a resin. A cut section is formed from a top surface of the sealed resin to a position that reaches a grounding electrode arranged in the substrate at a boundary section of the electronic component module so as to expose the grounding electrode. A conductive paste is applied on side surfaces and the top surface. Then, a conductive thin film is formed by spin coating, and the electronic component module is cut.
1. A method for manufacturing an electronic component module, comprising:
batch-sealing, with a resin, a collective substrate including a plurality of electronic component modules including a plurality of components;
forming a cut section from a top surface of the sealed resin to a position that reaches a grounding electrode arranged in the collective substrate at a boundary section of the plurality of electronic component modules so as to expose the grounding electrode; and
applying a conductive paste on side surfaces and a top surface of the plurality of electronic component modules, and then cutting the electronic component modules along the cut section; wherein
a conductive thin film is formed by spin coating after applying the conductive paste.
2. The method for manufacturing an electronic component module according to claim 1 , wherein a cross-sectional shape in a direction substantially perpendicular to the cut section at a bottom of the cut section is a curved shape or a shape having a predetermined slope.
3. The method for manufacturing an electronic component module according to claim 1 , wherein the grounding electrode of the collective substrate exposed in the step of forming a cut is formed on each of four side surfaces of the electronic component module.
