Description

Technical Field

[0001] The present invention relates to the technical field of electroplating fixtures, in particular to an electroplating fixture for an FPC (Flexible Printed Circuit Board) (VCP) electroplating production line. Background Art

[0002] As electronic devices are rapidly developing towards being thinner and more flexible, flexible printed circuit boards are increasingly used in electronic products. In the production of FPCs, vertical continuous plating (VCP) technology has become one of the key processes due to its high efficiency and uniform plating characteristics. Plating fixtures are the core components of the VCP production line.

[0003] Traditional electroplating fixtures generally use a fixed clamping structure to fix the FPC soft board through rigid clamping points. However, in actual production, different products have different requirements for the thickness of the soft board. For example, the thickness of the thin board is about 0.05mm, while the thickness of the thick board is about 0.3mm. For thicker soft boards, insufficient clamping force can easily cause the board to shift during the electroplating process, resulting in uneven coating. For ultra-thin soft boards, excessive clamping force can easily cause material deformation or even damage. At the same time, after electroplating is completed, residual plating liquid is easily attached to the surface of the fixture and the surface of the soft board. The residual liquid not only accelerates the corrosion of the metal parts of the fixture, but also contaminates the cleaning medium when transferred to the water washing tank, increasing the burden of wastewater treatment.

[0004] For example, Chinese patent document CN109778289A discloses a plating fixture and a circuit board electroplating method using the plating fixture. The method accurately calculates the plating and clamping, and clamps the circuit board with the front side facing outward according to the relative growth coefficient of the plating thickness, thereby effectively reducing the unnecessary consumption of precious metals in the back electroplating and solving the residual liquid problem.

[0005] Chinese patent document CN221501290U also discloses an electroplating fixture, which improves installation efficiency by simultaneously installing an anode assembly and a workpiece to be electroplated on the same supporting assembly.

[0006] For example, Chinese patent document CN201245723Y discloses an electroplating fixture that guides the liquid medicine to flow down the end of a fixed clamp to eliminate damage to the circuit board caused by the liquid medicine and solve the pollution problem caused by residual liquid medicine.
