Title:
CHAMBER FOR SOLDERING AND FORMATION OF ITS ATMOSPHERE
Document Type and Number:
Japanese Patent JP3182209
Kind Code:
B2
Abstract:
PURPOSE: To enable the formation of the atmosphere of an extremely low oxygen concn. in a short time even if an inert gas is not excessively supplied into a chamber body.
CONSTITUTION: The chamber body 36 is internally delineated and formed by many partition plates to preheating zones 41, 42, 43, reflow zones 44, 45 and a cooling zone 46. An alcohol tank 62 housing isopropyl alcohol 61 is provided on the outside of the chamber body 36. A pipeline 63 led out of the tank 62 is internally provided with a pump 64 for controlling the supply rate of the alcohol to the inside of the chamber body according to the oxygen concn. in the chamber body. The pipeline 63 is connected to nozzles 65 mounted to the upper parts of the respective zones of the chamber body 36. The oxygen concn. in the chamber body decreases when the alcohol sprayed and gasified from the nozzles 65 into the chamber body 36 and the residual oxygen in the chamber body are brought into a vigorous reaction by a heater 66 for combustion.
