In general, electric/electronic products that are mass-produced and consumed are referred to as printed circuit boards (PCBs) or printed circuit board assemblies (PCBAs) for signal processing of electronic circuits. ) is used indispensably.

As global resource depletion becomes serious, industrial activities of mass production, mass consumption, and mass disposal of electrical and electronic waste are attracting attention as a circular resource as a solution to the depletion of natural resources.

Although printed circuit boards for signal processing of electronic circuits are indispensably used in wastes of electronic and electrical products discarded in large quantities, printed circuit boards are also generated in large quantities as wastes.

A printed circuit board consists of a board and a number of parts attached to the board. The board consists of about 30% of polyethylene (PE), polypropylene (PP), polyester, and polycarbonate. Plastic components, about 40% of poorly soluble compounds such as silica and alumina, and copper (Cu), iron (Fe), nickel (Ni), tin (Sn), lead (Pb), aluminum (Al), and zinc (Zn) It contains about 30% of common metals such as gold (Au), silver (Ag), and noble metal components such as palladium (Pd).

In particular, printed circuit boards contain 300-600 mg of gold (Au) and 2000-3000 mg of silver (Ag) per 1 kg, which is a very high content compared to the actual amount of gold contained in gold ore, which is about 7 mg/Kg. .

Therefore, technologies for recovering and recycling them have been actively proposed.

Most of the commercialized technologies for recovering metal from printed circuit board assembly (PCBA: Printed Circuit Board Assembly, hereinafter collectively referred to as PCBA) are put into high-temperature melting furnaces of non-ferrous smelters and melted after melting them together with conventional non-ferrous smelting. recovered by the process.

In the printed circuit board component separation device of Registered Patent No. 1511309 (2015.04.06.), a first feeder into which the printed circuit board is fed, and a screw-shaped second feeder that transfers the printed circuit board discharged from the first feeder in one direction. In a configuration consisting of a feeder, a part separation unit for separating parts mounted on a printed circuit board transported by the second feeder, and a heating unit disposed along the longitudinal direction of the part separation unit to apply heat to the printed circuit board, the part separation unit is again It is configured to include a cylindrical case and a plurality of brushes.

That is, it is possible to reduce the separation time while allowing the components to be easily separated from the printed circuit board on which a plurality of components are mounted without the need for an additional sorting operation.

However, in order to separate the parts from the printed circuit board, they are heated to a temperature higher than the melting point of the solder (above 250°C) by a heating unit such as an infrared heater along the longitudinal direction of the parts separation unit, and contaminants are released by the melting of the solder during heating. While this is generated, scattering dust is generated, and since gas is mainly used as a heating means, there is an uneconomical problem in that work costs are somewhat consumed.
