Abstract

The invention discloses a wet chemical processing equipment for printed circuit boards. A movable column is sleeved on the guide column, the top of the movable column is located above the frame, a second motor is embedded in the top of the movable column, and a push bar is sleeved at the convex position of the top of the gear, The adjustment plate is located in the adjustment groove; the replacement groove is opened at the bottom of the installation plate, one end of the first clamping plate and the second clamping plate is located below the installation plate, and the bottom edge of the installation plate is provided with In the inner groove, a movable top rod is connected to one side of the rotating shaft of the horizontal plate, and a spoiler is connected to the bottom cavity of the mounting strip through a return spring. The printed circuit board wet chemical processing equipment can perform continuous operation, reduce space occupation, and improve uniformity and efficiency during deposition.

Description

technical field [0001] The invention relates to the technical field of printed circuit board processing, in particular to a wet chemical processing equipment for printed circuit boards. Background technique [0002] When the printed circuit board is processed, it is usually necessary to use wet chemical treatment methods to chemically deposit and protect the surface of the printed circuit board, including pre-treatment, deposition preparation and post-treatment. In the deposition preparation, including activation → water washing → electroless nickel deposition Processes such as water washing→chemical immersion gold→water washing can form a layer of protection on the surface of the circuit board, but the existing wet chemical treatment equipment has the following problems during processing: [0003] Most of the existing wet chemical treatment equipment adopts step-by-step operation during deposition treatment, but it occupies a large area, and the deposition process needs to ...
