Abstract
A method of manufacturing an electronic device including a first electronic component mounted on one main surface of a wiring board by being thermo-compression bonded by means of a thermo-compression bonding tool with an adhesive resin interposed between a first area of the one main surface of the wiring board and the first electronic component, and a second electronic component mounted on a second area different from the first area of the one main surface of the wiring board by melting a soldering paste material and higher than the first electronic component in post-mounting height, and wherein the first electronic component is mounted before the mounting of the second electronic component.
Claims21
A method of manufacturing an electronic device including:
- a first electronic component mounted on one main surface of a wiring board by being thermo-compression bonded by means of a thermo-compression bonding tool with an adhesive resin interposed between a first area of the one main surface of the wiring board and said first electronic component;
- and
- a second electronic component mounted on a second area different from the first area of the one main surface of the wiring board by melting a soldering paste material and higher than said first electronic component in post-mounting height,
- said method comprising the step of:
- mounting said first electronic component before the mounting of said second electronic component.
A method of manufacturing an electronic device, comprising the following steps:
- a first step of placing a first electronic component on a first area of one main surface of a wiring board with an adhesive resin interposed therebetween, thereafter thermo-compression bonding the first electronic component by a thermo-compression bonding tool, bonding and fixing the first electronic component to the first area of the one main surface of the wiring board, and electrically connecting first connecting portions provided in the first area of the one main surface of the wiring board and electrode pads provided in the first electronic component by protruded electrodes interposed therebetween, respectively;
- and
- a second step of supplying a soldering paste material to second connecting portions provided in a second area different from the first area of the one main surface of the wiring board, thereafter placing electrodes of a second electronic component on the second connecting portions with the soldering paste material interposed therebetween, respectively, and subsequently melting the soldering paste material to thereby electrically connect the second connecting portions of the wiring board and the electrodes of the second electronic component respectively,
- wherein said first step is executed before the execution of said second step.
A method of manufacturing an electronic device including a first electronic component mounted on one main surface of a wiring board by being thermo-compression bonded by means of a thermo-compression bonding tool with an adhesive resin interposed between a first area of the one main surface of the wiring board and said first electronic component, and a second electronic component mounted on a second area different from the first area of the one main surface of the wiring board by melting a soldering paste material, said method comprising the steps of:
- mounting said second electronic component before the mounting of said first electronic component.
A method of manufacturing an electronic device, comprising the steps:
- a first step of placing a first electronic component on a first area of one main surface of a wiring board with an adhesive resin interposed therebetween, thereafter thermo-compression bonding the first electronic component by a thermo-compression bonding tool, bonding and fixing the first electronic component to the first area of the one main surface of the wiring board, and electrically connecting first connecting portions provided in the first area of the one main surface of the wiring board and electrode pads provided in the first electronic component by protruded electrodes interposed therebetween, respectively;
- and
- a second step of supplying a soldering paste material to second connecting portions provided in a second area different from the first area of the one main surface of the wiring board, thereafter placing electrodes of a second electronic component on the second connecting portions with the soldering paste material interposed therebetween, respectively, and subsequently melting the soldering paste material to thereby electrically connect the second connecting portions of the wiring board and the electrodes of the second electronic component respectively,
- wherein said second step is executed before the execution of said first step.
