Method for manufacturing electronic parts module

A method for manufacturing an electronic parts module, the electronic parts module comprising a base wiring layer having a wiring pattern and a circuit forming surface, the wiring pattern formed on the circuit forming surface and including a first land part to which a passive element is connected and a second land part to which an active element is connected;

• and a resin sealing layer intimately formed on the circuit forming surface and sealing the passive element and the active element, comprising:
• an adhesive layer forming process for forming an adhesive layer including solder particles on the circuit forming surface in range covering at least the first land part and the second land part;
• an active element mounting process for positioning a terminal of the active element on the second land part, sticking the active element to the base wiring layer through the adhesive layer by heating and pressing the active element onto the base wiring layer with a thermally pressing tool, and releasing the heating and pressing with the thermally pressing tool while the adhesive layer is semi-solidified;
• a passive element mounting process, after the active element mounting process, for positioning a terminal of the passive element on the first land part and sticking the passive element to the base wiring layer through the adhesive layer;
• and
• a pressing process for solidifying the adhesive layer and melting the solder particles by laminating and thermally pressing a thermosetting sheet onto the circuit forming surface so as to form the resin sealing layer.
