Then, the copper-bearing liquid is combined with another acid to precipitate the copper from the organic material. Another process, called electrowinning, uses electricity to extract copper out of the PLS onto thin metal sheets. The remaining liquid is known as raffinate, a waste product. Raffinate can contain concentrated amounts of TENORM.Get Price
Apr 05, 2019· Wet PCB Etching Using Acidic and Alkaline Methods. PCB etching is a process of removal of unwanted copper (Cu) from the circuit board. When I say unwanted, it is nothing but the non-circuit copper that is removed from the board. As a result, the desired circuit pattern is achieved.Get Price
Thewetetchingprocessis either isotropic (orientation independent) or anisotropic (orientation dependent), as shown in Fig. 5.17.Usually, mostwetetching processes are isotropic, which are adequate for geometries of greater than 3 μm. In isotropicwetetching , material is removed uniformly from all directions by HF or buffered HF solutions (NH 4 F and HF mixture).Get Price
