The PCB Tin Stripping Machine is a critical piece of equipment in the manufacturing process of printed circuit boards (PCBs), primarily used to remove residual tin layers from the circuit board surface after the etching process. This tin layer, originally serving as an etching resist, covers the copper foil to prevent dissolution of non-circuit areas by the etching solution. After tin stripping, the copper circuitry is fully exposed, forming the final conductive pathways and laying the foundation for subsequent processes such as solder mask coating and component soldering.
