Corrosion device for copper clad laminate

Abstract

The invention discloses a corrosion device for a copper clad laminate, which comprises a support, a corrosion groove, a liquid storage box and a magnetic centrifugal pump and is characterized in that a step-like part is arranged above the support, the corrosion groove is fixed on an upper step, a water tank is fixed on a lower step, a bulk liquid box is arranged at the high end of the corrosion groove, and the bulk liquid box is connected with a water outlet of the magnetic centrifugal pump through a pipeline; a water inlet of the magnetic centrifugal pump is arranged in parallel, and the water outlet of the magnetic centrifugal pump is arranged to be downward; and the pipeline connecting the liquid storage box with the water inlet of the magnetic centrifugal pump sequentially comprises a first movable connector, a switch and a second movable connector, and the height of a small section connected with the water inlet of the magnetic centrifugal pump is highest, and higher than the height of the second movable connector. In the corrosion device, the magnetic centrifugal pump is less prone to corrosion caused by leaked corrosion solution, the corrosion solution can not be spilt out on a groove body, and the corrosion device can be applied in manufacturing of a printed circuit board.

Description

technical field [0001] The invention relates to corrosion equipment, in particular to copper clad plate corrosion equipment used for the production of printed circuit boards. Background technique [0002] Chinese utility model patent ZL200720059530.9 discloses a copper-clad plate corrosion device, which includes a liquid storage tank, a pump, and a tank body. The tank body is slightly inclined. The liquid storage tank is located under the water outlet at the lower end of the tank body. It is connected with the water inlet of the pump, and the water outlet of the pump is set roughly horizontally at the high end of the tank body. On the bottom surface of the tank body, there are protrusions arranged in a regular arrangement of different heights. There is a funnel-shaped sewage outlet on the bottom surface of the liquid storage tank. The corrosion The equipment is suitable for the practice teaching of electronic technology in colleges and universities and innovation laboratorie...
