Ordinary board as TV panels generally made of copper, tin, tin and aluminum recycling, computer board mobile phone board to extract gold platinum silver and other precious metals. Circuit board: copper up, the circuit board is a thin copper (multilayer more), then tin, tin solder high recovery of electronic components, the most least, gold (gold plate, only the plating in the surface layer on the line). A printed wiring board composed mainly of three basic components: an insulating substrate, a conductive circuit and installation components. Type of complex printed circuit boards, species diversity, the content of the various components of the composition of the board and the substance is also a great difference. Circuit boards usually contain 30% plastic, 30% and 40% of an inert metal oxide. CHO polymer component mainly composed of plastic, halide and a nitrogen-containing polymer; the main component is an inert oxide silicic acid, alumina, and alkaline oxide; plus minor amounts of other oxides and carbonates.
