Abstract
Provided is a soldering apparatus including: a furnace body including a processing chamber in which boards are processed; a gasket provided at least to a part of the furnace body, and configured to seal the furnace body; a sealed space isolated from the processing chamber, and defined by the furnace body and the gasket; a gas supply apparatus configured to supply a first gas into the sealed space; and a measuring apparatus configured to measure one of pressure in the sealed space and concentration of a second gas in the sealed space.
Claims14
A soldering apparatus, comprising:
- a furnace body including an upper furnace body, a lower furnace body, and a processing chamber in which boards are processed;
- a gasket
- provided along an edge of the upper furnace body or the lower furnace body,
- configured to seal the furnace body,
- including a first seal and a second seal spaced apart from the first seal along the edge of the upper furnace body or the lower furnace body,
- including a third seal that effects sealing between the first seal and the second seal when the third seal of the gasket is in contact with the other of the upper or lower furnace body and the furnace body is closed, and
- including a fourth seal
- that effects the sealing between the first seal and the second seal when the third seal of the gasket is in contact with the other of the upper or lower furnace body and the furnace body is closed;
- and
- that is arranged away from the third seal;
- a sealed space
- isolated from the processing chamber, and
- defined between the first seal and the second seal of the gasket, between the upper furnace body and the lower furnace body, and at least by the furnace body, the first seal, the second seal, the third seal, and the fourth seal when the furnace body is closed;
- a gas supply apparatus configured to supply a first gas into the sealed space;
- a measuring apparatus configured to measure one of
- pressure in the sealed space, and
- concentration of a second gas in the sealed space;
- and
- a control apparatus capable of communicating with the measuring apparatus,
- wherein the control apparatus is configured to determine whether the one of the pressure and the concentration received from the measuring apparatus has reached a predetermined threshold.
