Abstract
The utility model discloses an electroplating edge strip for PCB (Printed Circuit Board) electroplating. The electroplating edge strip is a stainless steel strip which has fixed specifications, wherein the stainless steel strip is formed through cutting laminated waste stainless steel plates, and the sectional dimension of the stainless steel strip is 40mm*625mm. A role of current spreading and thin board supporting is played through mounting the stainless steel strips at the two sides of a PCB, and the stainless steel edge strips can be recycled, so that the situation of electroplating edge strip lack is avoided; and furthermore, a cost recovery process can be carried out through tin removing and copper stripping.
Description
Technical field
The utility model relates to PCB electroplating technology field, relates in particular to a kind of plating edge strip of electroplating for PCB.
Background technology
In general PCB manufacturing processed, because different orders have different structures: the order that the part circuit is intensive or thickness of slab are less than the order of 1.0mm, in the PCB electroplating process, the edge of wiring board is high galvanic areas, and the edges of boards of dense wire plate the short circuit of thick folder film easily occurs plating and scrap.
The way of prior art is to increase auxiliary edge strip to come scattered current, thin plate (thickness of slab is less than 1.0mm) also needs the webbing bar to come the support plated scaffold simultaneously, therefore electroplate the edge strip demand very large, the copper bound bar that uses useless plate to cut can not recycle, the quality problem that regular appearance brings because of the edge strip deficiency.
In short, there is following drawback in the copper bound bar that is cut into of the useless plate of existing use:
1, consumption is large, can not recycle;
2, part is discarded the copper bound bar thin thickness (thickness is less than 1.2mm) that plate cuts, and does not play supporting role;
3, to sell off price low for copper-plated copper bound bar, presses 30% of copper valency and sell, and causes the cost waste.
In view of this, prior art haves much room for improvement and improves.
The utility model content
In view of the deficiencies in the prior art, the utility model purpose is to provide a kind of plating edge strip for the PCB plating.The problems such as the consumption that is intended to solve the copper bound bar existence that in prior art, the useless plate of use is cut into is large, underbraced, cost waste.
The technical solution of the utility model is as follows:
A kind of plating edge strip for the PCB plating, wherein, described plating steel bar has the fixedly stainless steel strip of specification for being cut into by the discarded stainless steel plate of lamination; The sectional dimension of described stainless steel strip is 40mm * 625mm.
Described plating edge strip for the PCB plating, wherein, described discarded stainless steel plate is 316 stainless steel plates, it is of a size of 1143mm * 1295mm.
Beneficial effect:
The application's the plating edge strip that is used for the PCB plating by being contained in the both sides of pcb board, plays the effect of scattered current and support thin plate, and the stainless steel edge strip can be recycled, solve the situation that edge strip lacks of electroplating, in addition, can also carry out the cost recovery processing by moving back tin stripping copper.
Description of drawings
Fig. 1 is the schematic diagram of the plating edge strip of electroplating for PCB of the present utility model when carrying out electroplating clamp plate.
Fig. 2 is the size schematic diagram of the plating edge strip of electroplating for PCB of the present utility model.
Embodiment
The utility model provides a kind of plating edge strip of electroplating for PCB, and is clearer, clear and definite for making the purpose of this utility model, technical scheme and effect, below the utility model further described.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
See also Fig. 1, the schematic diagram when it carries out electroplating clamp plate for the plating edge strip for the PCB plating of the present utility model.As shown in the figure, described plating edge strip 10 has the fixedly stainless steel strip of specification for being cut into by the discarded stainless steel plate of lamination; The sectional dimension of described stainless steel strip 10 be 40mm * 625mm(namely long L be 625mm, wide H is 40mm, as shown in Figure 2).
Wherein, described plating edge strip 10 is at the plate of Electroplating Production dense wire or the thickness of slab pcb board 20 less than 1.0mm, and the stainless steel edge strip is contained in the both sides (pcb board top be provided with fly to cling to 30) of pcb board 20, plays scattered current and supports the effect of thin plate.Described plating edge strip 10 is cut into by the discarded stainless steel plate of lamination has fixedly specification, and wherein, the lamination waste steel plate refers to steel plate and has the problems such as serious depression, scuffing, and the plate of extrusion can not satisfy quality requirements and the steel plate scrapped.
Further, described lamination waste steel plate is 316 stainless steel plates, and it is of a size of 1143mm * 1295mm.
The below introduces lower production and use procedure of electroplating edge strip 10, and its flow process is as follows: lamination waste steel plate → cut → assist copper facing → move back tin → stripping copper → assist copper facing → move back tin → stripping copper → assist copper facing.
Wherein, cut and can adopt outer sending out to cut, because of in the present embodiment, the lamination waste steel plate is 316 stainless steel plates, and the machine that requires to want special-purpose cuts.Move back tin and will pass through copper facing, zinc-plated flow process because of edge strip at electroplating work procedure, as peel copper tin and mix, sell off price low, press 30% of copper valency and sell.
It is as follows that it saves pricing:
Suppose that 3 lines of figure electricity produce 680 cylinder plates every day, 4 edge strips of every cylinder plate, the edge strip consumption is 70720 per month; The weight of copper that every stainless steel edge strip peels is 20g left and right (length edge strip weight in average), and the weight of copper that peels of edge strip is at 1414kg per month; To sell off price be 17.5 yuan/kg to the copper scrap edge strip in the past, can sell 24745 yuan by the copper that this price peels; It is 50 yuan/kg that the copper that peels is sold off by useless lamination waste copper foil price, can sell off 70700 yuan by this price; The copper that peels is per month sold off price can increase by 45955 yuan.
And need the cost of input as follows:
37350 yuan of stainless steel edge strip processing charges; 13800 yuan of unit clamp buying expenseses; Sell off price after the depreciation of lamination waste steel plate and be about 500 yuan=90000 yuan of 180 *; Input cost adds up to 141150 yuan; . stripping copper increase and decrease 1 people, 2200 yuan of wages.
So calculate, saving per month cost after the stainless steel edge strip came into operation 4 months is 43755 yuan, and its promotion prospect is better.
In sum, the plating edge strip for the PCB plating of the present utility model, described plating steel bar has the fixedly stainless steel strip of specification for being cut into by the discarded stainless steel plate of lamination; The sectional dimension of described stainless steel strip is 40mm * 625mm., by being contained in the both sides of pcb board, playing scattered current and support the effect of thin plate, and the stainless steel edge strip can be recycled, solve the situation that edge strip lacks of electroplating, in addition, can also carry out cost recovery and process by moving back tin stripping copper.
Should be understood that; application of the present utility model is not limited to above-mentioned giving an example; for those of ordinary skills, can be improved according to the above description or conversion, all these improve and conversion all should belong to the protection domain of the utility model claims.
