With the fast rapid development of modern technology, electronic products are used everywhere in our daily life. But it has been the fastest growing waste streams in our country, and a bad fact is that most of this e-waste ends up in landfills and incinerators. Only less than 30 percent of total old electronic products were recovered for recycling. Such a shame, considering your old electronics are treasures of valuable materials that can be extracted, processed, and reused in a variety of products.
Some of the most valuable metals that can be recovered from electronics are hidden in what are known as their printed circuit boards (PCBs). It is the board base for physically supporting and wiring the surface-mounted and socketed components of an electronic device. PCBs are found in almost all types of electronics – from your computers, cell phones, and cameras to your DVD players, televisions, and even some toys. Simple electronic devices usually have single-layer PCBs, while complex ones like computer motherboards can have up to 12 layers.
