PCB assembly process is the most critical step in developing any electronic product, so here we would like to talk about the all the PCB assembly process steps. Following the PCBA process will ensure that the printed circuit …
So here comes PCB etching. PCB etching is a critical step in PCB manufacturing, which removes the unwanted copper from a substrate to create the desired circuit patterns for electronic components. This process involves applying a protective mask to outline the circuitry and submerging the PCB in an etching solution that dissolves the exposed copper.
5.1.3 Crushing. After disassembly process, the LIBs need coarse shredding or fine crushing to reduce the granularity of the materials for further recycling [134]. The battery shredding or crushing process can be executed under an inert gas environment such as carbon dioxide to prevent the risk of thermal runaway and reduce pollution [135].
