Abstract
Description
Technical Field
[0001] This utility model belongs to the field of recycling technology, and more specifically relates to a waste printed circuit board recycling device. Background Technology
[0002] In the recycling process of waste printed circuit boards, some electronic components and PCBs on the circuit boards have reuse value and can be reused through refurbishment. Currently, most electronic components are soldered to the PCB board using solder. Therefore, the main way to disassemble them is to use a hot air gun to melt the solder, use a desoldering pump to remove the molten solder, and then remove the electronic components from the board. Since the disassembly of electronic components and the use of a desoldering pump need to be done simultaneously, manual disassembly usually involves holding a hot air gun in one hand and a desoldering pump in the other to remove the molten solder before manually removing the electronic components from the board. This method is time-consuming and laborious. Utility Model Content
