Abstract
The utility model discloses a floating type cathode shielding plate which is mainly provided with two vertical side plates; two inclined plates extend down from the adjacent top edges of two side plates at proper angles of inclination ; and the two inclined plates are connected with a positioning rib and are respectively provided with slotted holes formed at intervals to form a plurality of penetration areas and shielding areas which are spaced. The floating type cathode shielding plate naturally floats on an electroplating liquid level of an electroplating bath for circuit boards to be inserted in the middle of the floating type cathode shielding plate; and due to the length difference, the circuit boards are stayed at different bath liquid depths, thereby passing through the penetration areas and the shielding areas formed by the slotted holes of the inclined plates during electroplating so as to achieve the effect of limiting the overcurrent and further enabling the electroplating quality of the circuit boards to conform to the demands of tolerance range.
Description
Technical field
The utility model relates to a kind of floating type negative electrode shield, particularly relates to a kind ofly reaching the effect that limited multiple current, and then makes the electroplating quality of circuit card conform with the floating type negative electrode shield of tolerance zone demand.
Background technology
Existing electroplating device usually as shown in Figures 1 and 2, in plating tank 1, be provided with spaced negative electrode shield 2, wherein, described negative electrode shield 2 is provided with inside slope section 21, and a through hole 22, and it is fixing with negative electrode shield 2 to make the positioning rib 11 of plating tank 1 be arranged in through hole 22, be inserted in negative electrode shield 2 central authorities with power circuit board 3 and consist of the location, make circuit card 3 tops when rocking, also rock thereupon the below, with the quality of guaranteeing to electroplate.But when circuit card 3 is being electroplated, because the higher electric current of existence of lower end, cause circuit card 3 lower ends to electroplate blocked up and surpass tolerance zone (can only reach approximately the scope of tolerance 15%), the circuit card of producing easily causes the problems such as short circuit of circuit.In view of this applicant is to adhere to this business experience for many years of being engaged in, and through constantly studying, testing, satisfies germinating and improves a kind of floating type negative electrode shield, so that circuit card is reached tolerance zone when electroplating, guarantees the quality of circuit card.
The utility model content
Main purpose of the present utility model makes circuit card when electroplating for a kind of floating type negative electrode shield is provided, and can reach the effect that limited multiple current, and then make the electroplating quality of circuit card conform with the tolerance zone demand.
For achieving the above object, the utility model provides a kind of floating type negative electrode shield, mainly be provided with two vertical side plates, by the contiguous upper edge of biside plate, extend two swash plates with suitable angle of inclination downwards respectively, make two swash plates be connected in a positioning rib, wherein, this two swash plate is respectively equipped with spaced slotted hole, to form a plurality of penetrating regions and the shelterarea at interval.Floating type negative electrode shield is floated on the plating liquid level of plating tank naturally, it is central to be inserted in floating type negative electrode shield with power circuit board, and because the circuit card difference in length is stagnated in the different tank liquor degree of depth, thereby when electroplating, be able to penetrating region that slotted hole consists of and shelterarea by swash plate, reach the effect that limited multiple current, and then make the electroplating quality of circuit card conform with the demand of tolerance zone.
Aforesaid floating type negative electrode shield, the slotted hole of wherein being located at swash plate is to be horizontal being spaced.In addition, this side plate and two swash plates and positioning rib are made with the PP plastics.
The utility model cooperates by side plate and extends, and have two swash plates of slotted hole with side plate, consists of floating type negative electrode shield, makes circuit card when electroplating, and can reach the effect that limited multiple current, and then make the electroplating quality of circuit card conform with the tolerance zone demand.

Embodiment
Please consult simultaneously Fig. 3 and Fig. 4, be stereographic map of the present utility model and sectional view.As shown in the figure, the utility model is provided with two vertical side plates 4, by biside plate 4 contiguous upper edges, extend two swash plates 5 with suitable angle of inclination downwards respectively, make two swash plates 5 be connected in a positioning rib 6, wherein, this two swash plate 5 is respectively equipped with spaced slotted hole 51, to form a plurality of penetrating regions and the shelterarea at interval, in the present embodiment, this side plate 4 and two swash plates 5, and positioning rib 6, be made with the PP plastics, the described slotted hole 51 of being located at two swash plates 5 is horizontal arrangement.
Combination by aforementioned components, consist of floating type negative electrode shield 100, floating type negative electrode shield 100 is able on the plating liquid level that floats on plating tank of nature, be inserted in floating type negative electrode shield 100 central authorities with power circuit board, and because the circuit card difference in length is stagnated in the different tank liquor degree of depth, thereby when electroplating, be able to by two swash plates 5 slotted hole 51 consist of penetrating region and shelterarea, reach the effect that limited multiple current, and then make the electroplating quality of circuit card conform with the demand of tolerance zone.
See also Fig. 5, for illustration is implemented in use of the present utility model.As shown in the figure, the utility model in use, by the PP plastics proportion principle lighter than water, make on the plating liquid level that floats on plating tank 1 of floating type negative electrode shield 100 natures, be inserted in the central authorities of floating type negative electrode shield 100 with power circuit board 3, when circuit card 3 is pressed on central authorities, be able to the difference because of circuit card 3 length, floating type negative electrode shield 100 is stagnated in the different tank liquor degree of depth, thereby when electroplating, be able to penetrating region and shelterarea that the slotted hole 51 by two swash plates 5 consists of, reach the effect of covering super-high-current, thereby limit too much electric current, make the electric current of circuit card 3 lower ends more even, and then make the electroplating quality of circuit card 3 conform with the demand of tolerance zone.
The utility model is according to actual test, the tolerance zone of the finished product of electroplating can reach ± and 8 ~ 10%, only can reach ± 15% tolerance zone than existing negative electrode shield, the blocked up problem of line thicknesses is caused in circuit card 3 lower ends of improving that can be certain because electric current is excessive, thereby improves the quality of circuit card 3.
