For circuit boards containing electronic components, you can first use the disassembler to dismantle the electronic components on the circuit board, and then the dismantled electronic components and the motherboard for further processing. For circuit boards that do not contain electronic components, they can be directly crushed and recycled, in which resin, fiber and copper can be separated to obtain high-grade metal, recycled and sold for profit. The whole process can be equipped with fume treatment equipment to avoid secondary pollution to the environment. Therefore, circuit board recycling has high value.
