Embodiment Construction

[0029] The principle of the present invention will be further described in detail below in conjunction with the accompanying drawings and exemplary embodiments, so as to make the technical solution of the present invention clearer.

[0030] figure 1 is a perspective view of a desoldering device according to an exemplary embodiment of the present inventive concept. In the drawings, the X-axis, Y-axis and Z-axis are not limited to the three axes of the rectangular coordinate system and can be interpreted in a wider sense. For example, the X-axis, Y-axis, and Z-axis may be perpendicular to each other, or may represent different directions that are not perpendicular to each other.

[0031] refer to figure 1 , The stripping equipment 1000 according to an exemplary embodiment of the present inventive concept may include a stripping tank assembly 1100 and a solution tank 1200 .

[0032] Such as figure 1 As shown in , the stripping tank assembly 1100 may at least partially overlap...

Abstract

Disclosed is a tin stripping device, which includes a tin stripping bath assembly. The tin stripping tank assembly includes: a shell; the tin stripping tank is arranged in the housing and used to accommodate the tin stripping liquid; the electrode part is arranged in the tin stripping tank and includes a cathode plate and a conductive brush; The tin bath includes a plurality of thinning roller groups and water retaining roller groups. Each thinning roller group includes upper thinning rollers and lower thinning rollers arranged symmetrically to each other. The opening corresponding to the inlet and outlet of the tin stripping equipment. The cathode plate is arranged on at least one of the top and the bottom of the tin stripping tank and is smaller in length and / or width than the tin stripping tank. The conductive brushes may be arranged alternately with the thinning roller sets and extend in a direction parallel to the extending direction of the thinning roller sets, so that the conductive brushes are in contact with the PCB board during the desoldering process. During the tin stripping process, the electrode part and the transmission part can be completely immersed in the tin stripping solution.

Description

technical field [0001] The invention relates to the technical field of stripping metal coatings, in particular to a tin stripping device. 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 layer and the substrate Cu need to be removed for subsequent processing. ...
