Novel anti -corrosion PCB board

The utility model provides a novel anti -corrosion PCB board, a plurality of shrinkage pools have been seted up to PCB board lateral wall, the shrinkage pool inner wall covers there is adsorption material, PCB board surface covering has corrosion -resistant material. Through the setting of shrinkage pool and the agent of shrinkage pool internal adsorption, can pass through further to guarantee to corrode the material through the recess and be difficult for escaping from the shrinkage pool in the adsorbent adsorbs the shrinkage pool with corroding the material. To corrode the material and adsorb in the shrinkage pool, can prevent that these from corroding materials to the corruption on PCB sheetmetal layer and then cause the damage of PCB board.
