Abstract

The invention discloses an electric conduction brush used for a solder stripping device and the solder stripping device comprising the electric conduction brush. The solder stripping device can comprises a cathode plate and the electric conduction brush making contact with a PCB so as to apply voltage to the PCB in the solder stripping process. The electric conduction brush can comprise a brush handle electrically connected to an external power source, brush wires fixed and electrically connected to the brush handle, supporting parts which are overlapped with the brush wires and fixed to the brush handle together with the brush wires so as to support the brush wires, and a fixing part. The fixing part comprises a cover plate, and the cover plate covers part of the brush wires and part of the supporting parts and is combined to the brush handle so as to fix the brush wires and the supporting parts to the position between the brush handle and the fixing part. By the adoption of the solder stripping device comprising the electric conduction brush, the solder stripping rate can be increased, and the solder stripping effect is improved.

Description

technical field [0001] The invention relates to the technical field of metal plating stripping, in particular to a conductive brush used for tin stripping equipment and tin stripping equipment including the same. Background technique [0002] Printed Circuit Board (PCB) is one of the important parts of the electronics industry and is the support of electronic components. Usually, in the process of manufacturing printed circuit boards, after the circuit pattern is formed by screen printing or photochemical method, it is necessary to plate tin on the conductive pattern to form a corrosion-resistant metal protective layer to protect the circuit pattern, and then it can be used in subsequent alkali Protect the circuit pattern from being damaged by corrosion during the permanent etching process. After the alkaline etching is completed, the tin protective layer formed on the surface of the circuit pattern and the copper-tin alloy formed at the interface between the tin protective...
