Problems solved by technology

[0003] However, once a printed circuit board is mounted in a product and set in a housing etc., it is practically impossible today to trace manufacturing control information etc. about a printed circuit board even when items of information for identifying those components or assembly machines have been written To the case of the IC label
Therefore, it is difficult to know at home which PCB is used for a product
[0004] Therefore, when home appliances already in the market need to be replaced by new products and some home appliances are to be recalled, there is a problem that the recall must be notified only by newspaper advertisements, etc.

[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...

Abstract

A method for identifying a device to be recalled, which enables identification of a location of the device to be recalled, the method comprising: a collecting step (S2 and S4) for extracting from a device with an IC tag via a communication network collecting information items stored in the IC tag; a collating step (S6) for collating the information items collected in the collecting step with information items about the equipment to be recalled; and an identifying step (S8) for Devices to be recalled are identified from devices with IC tags based on the collation result.

Description

technical field [0001] The present invention relates to a method of identification and heating of equipment to be recalled, and in particular to a method of identification and heating of equipment to be recalled using information items stored in individual integrated circuit (IC) tags method. Background technique [0002] A method for writing information items for identification of Components assembled on printed circuit boards or assembly machines for assembling these components. This method of reading information items stored in the IC tag enables acquisition of manufacturing control information of printed circuit boards, quality information of components, and the like to ensure traceability. [0003] However, once a printed circuit board is mounted in a product and set in a housing etc., it is practically impossible today to trace manufacturing control information etc. about a printed circuit board even when items of information for identifying those components or assem...
