The invention discloses a combined high-speed
electroplating shielding device, and relates to the technical field of high-speed
electroplating. The device mainly comprises a base, two liquid sprayingboxes, two separating cloth frames, two
anode titanium frames and two pressing plates and is positioned in a working tank; and plating liquid in a
liquid storage tank is lifted by a filter, enters theliquid spraying boxes through a liquid inlet
pipe of the working tank, and a base liquid inlet
pipe and a base liquid outlet
pipe of the shielding device, and then flows to a
cathode area through pores in the liquid spraying boxes. According to the device, anodes are arranged above and below a
cathode, and the separating cloth frames have shielding effects on the two edges of the
cathode; throughbase standby screw holes and the separating cloth frames of different widths, one set of shielding device can adapt to high-speed
electroplating of IC
lead frame type metal sheet strips of various width specifications, and the influence of the width change of the cathode on the thickness distribution of plating
layers is reduced; and for strip cathodes of different width specifications, the distance between the two edges and PP plates of the liquid spraying boxes can be fixed at an optimal value, so that the situation that power lines on the two edges are dense due to the width change of thecathode is avoided, and plating
layers on the edges of the cathode are prevented from being too thick or scorched.
