Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To provide a reflow apparatus which reduces the leak of heat and that of nitrogen in a reflow soldering operation. SOLUTION: An upper-part labyrinth 11 and a lower-part labyrinth 18 are divided respectively into a plurality of labyrinth parts, and the height of every place on a board 15, i.e., the height of every electronic component, is detected by a line sensor.

IPC: B23K26/12
Filed: 1989-04-28
Abstract: PURPOSE:To provide the subject irradiating apparatus which can be manufactured at a low cost, by arranging a backup member which prevents deformation of an aperture plate toward inside of a vacuum chamber by being brought into face-contact with inner face side of the aperture plate possible to transmit the laser beam and loading a part of outer force to the member to make the aperture plate thin. CONSTITUTION:After making the vacuum chamber 3 high vacuum under condition of laying the material 6 to be irradiated on a laying table 5, the laser beam is emitted from a laser beam oscillator 10. Then, the laser beam is transmitted to optional opening part 19d in the backup member 19 through an outer aperture plate 13 in the oscillator 10. Further, this laser beam irradiates the material 6 to be irradiated through an inner aperture plate 16, second and third plates 26, 27. Then, gas is generated from the material 6 to be irradiated, but as the inner aperture plate 16 is arranged inside of the outer aperture plate 15, a large part of the gas is screened with this inner aperture plate 16 and on the outer aperture plate 15, sticking of impurity contained in the gas is little. In this case, exchange of the inner aperture plate 16 can be executed at a low cost, because the plate 16 can be made thin without any consideration of pressure difference between the inner and outer faces and reduction of the cost can be executed.
