Fixture, circuit board with fixture, and electronic-component mounted body and method of manufacturing the same

A circuit board with a fixture, comprising:

• a fixture mounted on a circuit board, for placing an electronic component;
• and
• electrodes formed on the circuit board with the fixture,
• wherein the fixture comprises a movable pawl for fixing an electronic component and a positioning wall for positioning an electronic component, the positioning wall extending continuously along four sides of the electronic component,
• the positioning wall defines inner wall faces of the fixture,
• the electrodes are exposed between opposing portions of the positioning wall, and
• the movable pawl has a surface that faces downward and is substantially parallel with a top face of the electronic component, the surface being brought into contact with the top face of the electronic component so that the electronic component is pressed against the electrodes.

An electronic-component mounted body, comprising:

• a circuit board with electrodes;
• a fixture;
• and
• an electronic component with electrodes,
• the electronic component being placed on a circuit board using the fixture, and
• bumps formed on the electrodes of the electronic component or on the electrodes on the circuit board,
• wherein the fixture comprises a movable pawl and at least one pair of positioning walls,
• the movable pawl fixes the electronic component to the circuit board,
• the at least one pair of positioning walls control a position of the electronic component in a direction parallel to a surface of the circuit board with the electronic component placed therebetween,
• the electrodes of the electronic component are connected to the electrodes on the circuit board formed between the at least one pair of positioning walls, and
• the bumps and the electrodes on which the bumps are not formed are connected to each other with a conductive material interposed therebetween.

A method of manufacturing an electronic-component mounted body, comprising:

• providing a circuit board provided with a fixture and electrodes, the fixture having a moveable pawl and at least one pair of positioning walls, wherein the at least one pair of positioning walls are inner wall faces of the fixture,
• the electrodes being formed to be exposed between the at least one pair of positioning walls;
• and
• connecting electrodes of an electronic component and the electrodes on the circuit board by fitting the electronic component between the at least one pair of positioning walls and fixing the electronic component by the movable pawl, and
• forming bumps on the electrodes of the electronic component or on the electrodes on the circuit board, the bumps and the electrodes on which the bumps are not formed are connected to each other with a conductive material interposed therebetween.
