</script>Generally, e-waste contains 3–5% PCBs, which are the most valuable part of WEEE. Structure, material composition, sources, and value of WPCBs are covered in detail in this chapter. Bare and populated WPCB and electronic component chemical compositions are compared. WPCB grades and prices are given along with valuable metal contents. Value chain and economic value of WPCB recycling are explained graphically. PCB types and assembly structure, methods of fastening electronic components on PCBs, and soldering methods and desoldering for electronic component are described elaborately. The effects of e-waste recycling on metal resources are explained. Characterization and amount of wastes from PCB manufacturing processes are clarified.
