[0041] A system for identifying electric appliances to be recalled in a first embodiment of the present invention will be described below with reference to the drawings.
[0042]
[0043] figure 1 is a diagram illustrating the structure of a system for identifying equipment to be recalled. The system 30 for identifying equipment to be recalled is a system for identifying household appliances to be recalled, including: household appliances 38 to 46 (air conditioners 38, electric ovens 40, television receivers) installed in houses 32 42, refrigerator 44, washing machine 46), IC tag reader-writer 34, and recall database equipment 37 connected with IC tag reader-writer 34 placed in each house 32 via Internet 36.
[0044] IC tags 48 are attached to home appliances 38 to 46 provided in the respective houses 32 . Each IC tag 48 includes information items related to each product when it was manufactured (such as product name, style, date of manufacture, serial number, name of used...

[0111] Next, a reflow oven in a second embodiment of the present invention will be described with reference to the drawings.
[0112] Figure 12 is a diagram of the inside of a reflow oven. The reflow furnace 109 accommodates the printed circuit board 52, heats the printed circuit board 52 to melt the solder of the electronic components 132 to 136 mounted on the printed circuit board 52, and then cools them to fix the electronic components 132 to 136 to the printed circuit board 52 board 52.
[0113]However, electronic components have thermal characteristics, such as heat-resistant temperature and temperature acceleration. Therefore, in the case where the temperature inside the reflow furnace 109 rises rapidly, components may cause steam explosion. The temperature inside a conventional reflow oven is kept constant because it needs to be kept high to use solder that contains little lead. Therefore, the temperature inside the reflow furnace must be set at an appropriate temp...
