Abstract
The utility model discloses a connecting sheet structure connected on a PCB, which comprises a pure nickel connecting sheet or a nickel-coated connecting sheet connected on the PCB. A copper layer isarranged on the surface of the connecting sheet contacting with the PCB. By arranging the copper layer on the surface contacting with the PCB, the connecting sheet structure achieves simple structureand ingenious conception, enables connecting intensity to be strengthened by more than one time, and leads hazardous substance or other environmental protection index to reach the standards of national and international related regulations.
Description
Technical field
The utility model relates to PCB circuit board manufacturing technology field, is the brace structure on a kind of PCB of being connected circuit board specifically.
Background technology
At present, in the Welding Structure of pure nickel or nickel plating brace and PCB circuit board, because tin and the welding of pure nickel material do not form firm alloy-layer, make weld strength poor, cause brace to come off easily from the PCB circuit board, particularly adopt the unleaded halogen tin cream that adds to carry out Reflow Soldering when welding, intensity can further descend, and is difficult to guarantee the stable of product quality.For this reason, brace and the PCB circuit board Welding Structure that designs a kind of weld strength height, constant product quality is design concept of the present utility model.
The utility model content
The purpose of this utility model is the shortcoming that overcomes above-mentioned prior art, provide a kind of simple in structure, be skillfully constructed, weld strength height, constant product quality and the brace structure of welding mutually with the PCB circuit board, the syndeton intensity of the comparable prior art of this brace structure is enhanced about more than once, and harmful substance and other environmental protection indexs all reach the standard of country, international relevant regulations.
The utility model can be achieved through the following technical solutions:
A kind of brace structure that is welded on the PCB circuit board comprises the pure nickel or the nickel plating brace that are welded on the PCB circuit board, described brace with surface that the PCB circuit board welds mutually on be provided with the copper layer, described copper layer comprises copper plate or compound ambrose alloy etc.
Described phosphor-copper thickness of coating is 0.002～0.02MM.
The utility model at first is provided with the copper layer on pure nickel or nickel plating brace and material surface that the PCB circuit board welds mutually, then with its punch forming, carry out anti-oxidation processing at the copper layer place of pure nickel or nickel plating brace again, this anti-oxidation processing can adopt chemical passivation and surface anti-oxidation technology to handle, this technology is a prior art, is not described in detail at this.
The utility model compared with prior art has following advantage:
The utility model pure nickel or nickel plating brace with surface that the PCB circuit board welds mutually on be provided with the copper layer, it is simple in structure, be skillfully constructed, its bonding strength is enhanced about more than once, and harmful substance and other environmental protection indexs all reach the standard of country, international relevant regulations.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is brace and PCB circuit board connection diagram.
Embodiment
Come the utility model is further described below in conjunction with Figure of description:
Shown in accompanying drawing 1 and accompanying drawing 2, a kind of brace structure that is connected on the PCB circuit board, comprise the pure nickel or the nickel plating brace 1 that are connected on the PCB circuit board 3, described brace 1 with surface that the PCB circuit board welds mutually on be provided with copper layer 2, described copper layer is a copper plate.
Described copper plate 2 thickness are 0.002～0.02MM.
The utility model at first is provided with copper plate on pure nickel or nickel plating brace and surface that the PCB circuit board welds mutually, then with its punch forming, carry out anti-oxidation processing in copper facing place of pure nickel or nickel plating brace again, this anti-oxidation processing can adopt chemical passivation and surface anti-oxidation technology to handle, this technology is a prior art, is not described in detail at this.
The utility model pure nickel or nickel plating brace with surface that the PCB circuit board welds mutually on be provided with the copper layer, it is simple in structure, be skillfully constructed, its bonding strength is enhanced about more than once, and harmful substance and other environmental protection indexs all reach the standard of country, international relevant regulations.
The above is preferred embodiment of the present utility model only, is not that the utility model is done any pro forma restriction; But the those of ordinary skill of all industry is all implemented the utility model technology with the above shown in the by specification accompanying drawing swimmingly; But all those skilled in the art can utilize the above technology contents that discloses and a little change, modification of making and the equivalent variations that develops in not breaking away from the technical solutions of the utility model scope, be equivalent embodiment of the present utility model; Simultaneously, all foundations essence technology of the present utility model all still belongs within the protection range of the technical solution of the utility model change, modification and the differentiation etc. of any equivalent variations that above embodiment did.
Claims (2)
1, a kind of brace structure that is connected on the PCB circuit board comprises the pure nickel or the nickel plating brace (1) that are connected on the PCB circuit board, it is characterized in that: described brace with surface that the PCB circuit board welds mutually on be provided with copper layer (2).
2, according to the described brace structure that is connected on the PCB circuit board of claim 1, it is characterized in that: described copper layer thickness is 0.002～0.02MM.
