Title: Method and device for reflow soldering
Inventor: NAGAI HIDEKI
IPC: H05K3/34
Filed: 2003-04-25
Abstract: <P>PROBLEM TO BE SOLVED: To prevent excessive heating of a work and defective soldering by conducting reflow soldering under a constant temperature while using a single heating medium within a vessel.  <P>SOLUTION: While a work 15 is supported in the middle layer of a sealed processing tank 21, the heating medium is accumulated in the lower layer and it is heated by a heater 24 to boil and evaporate it, thereby heating the work 15 by using the steam. The steam is cooled down and condensed by a cooler 25 provided in the upper layer within the processing tank 21, and it returns to the lower layer and is heated again. For example, a vacuum pump 31 is selectively activated to change a pressure within the processing tank in two stages. First, the pressure is set at a specified low level, thereby supplying a steam to the work 15 that is adjusted at a low boiling temperature corresponding to the specified pressure for preheating. Next, the inside of the processing tank 21 is set at a specified high pressure, thereby supplying a steam that is adjusted at a high boiling temperature corresponding to the specified pressure for reflow soldering.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
