JP2014024048A5 - Small electrical product identification method and sorting device - Google Patents

Description

A method for identifying many used small electrical products such as a mobile phone, an HDD (hard disk device), a digital camera, and the like according to the present invention and judgment criteria used in a sorting device will be described.
Table 1 shows the number of tantalum capacitors used in used mobile phones. 49 mobile phone products released in 1998-2007 were actually disassembled and mounted on an internal electronic board. This is the result of a survey of the number of tantalum capacitors that have been released by release year. As for models released after 2005, only an average of 4 or less is installed per unit, and it is clear that the number has been reduced to 1/3 or less compared to models released before 2004. . This is thought to reflect the rapid development of alternative designs from tantalum capacitors to ceramic capacitors started by each manufacturer around 2005, triggered by a shortage of raw materials for Ta and a surge in prices that occurred around 2000. . Therefore, it is appropriate to judge a model released before 2004 as a mobile phone with a high Ta content. (Note that some models released before 2004 continue to be manufactured and sold after 2005, so this release date does not necessarily coincide with the date of manufacture or sales. .)
Table 1 shows the results of a survey of used mobile phones, and the alternative design from tantalum capacitors to ceramic capacitors that each manufacturer started in 2005 was triggered by the shortage of Ta raw materials and price surges that occurred around 2000. Since it is thought that it reflects the rapid progress around the year, small electric products such as HDDs (hard disk drives) and digital cameras other than mobile phones are also released before 2004. It is reasonable to judge as a small electrical product with a high Ta content.
As described above, small electric products such as mobile phones, HDDs (hard disk devices), digital cameras, etc., have a small amount of Ta products with an average of more than 4 tantalum capacitors used per unit, and 1 There is a small electrical product B with a small Ta content of 4 or less on average using tantalum capacitors per unit.
