Provided is a collector sheet for a solar cell, and contributing to improvement of power generation efficiency. A collector sheet (5) for a solar cell is disposed on the rear surface side of a solar cell element (4), and is provided with: a circuit (54), which is formed on the front surface of a resin base material (53), and which is configured of a wiring section (541) composed of a metal, and a non-wiring section (542); and an insulating layer (52), which is formed on the circuit (54). Light extraction to the solar cell element (4) due to reflection from the insulating layer (52) is increased, said insulating layer being disposed at the element periphery of the solar cell element (4), by having a white pigment contained in the insulating layer (52), and power generation efficiency is improved even in a back contact solar cell element.

A repair apparatus includes a heating head device configured to heat a soldering member, which is soldered to a circuit board. The heating head device includes a heating head and a contact member heated by the heating head. The contact member is formed of a material having a spring characteristic and a thermal conductivity higher than a thermal conductivity of the heating head. The contact member is configured to be brought into contact with a soldered surface of the soldering member with an elastic force so as to melt a solder joining the soldering member to the circuit board.

Disclosed is a board reinforcing structure for reinforcing a circuit board in which an electronic component is mounted on a first surface, the electronic component having an electrode arranged in a rectangular-shaped region on the first surface. The board reinforcing structure includes a reinforcing member bonded to positions corresponding to corner parts of four corners of the rectangular-shaped region on a second surface provided on a side opposite to the first surface of the circuit board. In the board reinforcing structure, corresponding one of notches is formed in the reinforcing member at a position corresponding to one of the corner parts of the four corners of the rectangular-shaped region, and at least two apexes of the reinforcing member directed to an outside are formed to shape a contour thereof with the one of the notches.

A method of mounting a semiconductor device having bumps on a board having pads so that each of the bumps is joined to a corresponding one of the pads is provided. Adhesive to be hardened by heat is provided between the semiconductor device and the board. The method includes the steps of pressing the bumps of the semiconductor device on the pads of the board, and heating a portion in which each of the bumps and a corresponding one of the pads are in contact with each other. A pressure of the bumps to the pads reaches a predetermined value before a temperature of the adhesive to which heat is supplied in the above step reaches a temperature at which the adhesive is hardened.

In a method of production of a multichip package module, rough-pitch bare chips are positioned at first locations on a printed-circuit board, and the rough-pitch bare chips are temporarily attached to the board at the first locations. The rough-pitch bare chips are mounted on the board at the same time by applying heat and pressure to the rough-pitch bare chips simultaneously. A respective one of fine-pitch bare chips is positioned at a respective one of second locations on the board other than the first locations, and the respective one of the fine-pitch bare chips is mounted on the board by applying heat and pressure to the fine-pitch bare chips individually, in order to produce the multichip package module.
