Description

Technical Field

[0001] The invention relates to the technical field of circuit board electroplating, and in particular to an electroplating clamping tool for circuit board processing. Background Art

[0002] The names of circuit boards include: ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, circuit boards, PCB boards, aluminum substrates, high-frequency boards, thick copper boards, impedance boards, PCBs, ultra-thin circuit boards, ultra-thin circuit boards, printed (copper etching technology) circuit boards, etc. Circuit boards make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layouts. Circuit boards can be called printed circuit boards or printed circuit boards, and the English name is PC circuit boards and the birth and development of soft-hard boards-FPC and PCBs have given rise to a new product, the soft-hard board. Therefore, the soft-hard board is a flexible circuit board and a rigid circuit board, which are combined together according to relevant process requirements after lamination and other processes to form a circuit board with FPC characteristics and PCB characteristics.

[0003] At present, circuit board electroplating refers to the process of depositing a layer of metal film on the metal surface (usually copper) of the circuit board through electrolytic reaction. This film is usually electroplated with gold, silver, copper or nickel to improve the conductivity, corrosion resistance, wear resistance and other properties of the circuit board.

[0004] However, the current electroplating process plays an important role in circuit board processing. The formation of small holes or traces for powering and connecting the circuit board depends on the clamping tooling used in the electroplating process. Most of the existing electroplating clamping tools adopt a simple structure, such as a pure clamping type clamp, or a screw-fixed clamp. It is often only one set of clamps on a production line, which requires reciprocating disassembly and use, which is more troublesome. In addition, the installation and disassembly efficiency is low when the clamp is fixed with screws. Summary of the invention

The matching hole 13 is opened inside the fixed plate 2 12 and is adapted to the plug-in column 16.

[0030] Specifically, by providing a clamping mechanism, when in use, the handle 9 is pulled to rotate the clamping plate 8 toward the fixed plate 1 5, the circuit board is fitted on the fixed plate 2 12, and the internal hole is aligned with the adapter hole, and the handle 9 is released, so that the telescopic rod 10 moves under the action of the spring 11, thereby driving the clamping plate 8 and the plug-in column 16 to move, so that the plug-in column 16 passes through the inner hole of the circuit board and extends into the adapter hole, thereby clamping and fixing the circuit board, and at the same time, the magnet block 17 is used for magnetic adsorption and fixation, so that the circuit board is more stable during the electroplating process and the effect is better.

At the same time, a bracket 3 with a groove arrangement is used, and the plating liquid on the circuit board will flow along the two side edges to the grooves on the bracket 3, and then flow into the groove formed by the support plate 15 and the baffle 14.
