A kind of Electropolating hangers

Technical field

The utility model relates to hanger field, specifically a kind of Electropolating hangers.

Background technology

In the manufacturing process of flexible print circuit board (FPCB), plating is one of important handling process. Wiring board, in the time carrying out electroplating processes, need to be used hanger and coordinate, and hanger mainly plays the effect of conduction, support and retaining element therein. Particularly, carrying out before electroplating processes, flexible print circuit board need to launch and be anchored on hanger, and in electroplating process, wiring board is connected with electrode by hanger, and wiring board is electroplated production under the power supply function of electrode. In said process, the shape of hanger and the wiring board fixed form on hanger can greatly affect current delivery to the electric current uniformity coefficient on wiring board, electric current uniformity coefficient has determined quality, the uniformity etc. of coating, therefore the appropriate design of hanger and make electroplating total quality and the production efficiency of rear product significant.

At present, the hanger that the electroplating process of flexible print circuit board uses is all traditional fixing point-like contact conduction hanger, the mobile jib of this hanger is provided with all constant wiring board fixed terminals (generally adopting the mode being screwed) of quantity and position, and wiring board is fixed on hanger by above-mentioned fixed terminal. The fixed form of this point-like contact can not ensure the uniformity coefficient of wiring board conduction, and particularly as easy as rolling off a log between points have the bad situation of conduction to occur, thereby can make coating occur the situation that variable thickness causes, and affects yield and the production efficiency of product. In addition, because quantity and the position of fixed terminal all can not change, the size of wiring board can constantly convert, and therefore this traditional Electropolating hangers can not ensure the fixed support effect of every kind of wiring board, particularly itself and use while being not suitable for the less circuit board electroplating of length.
