Abstract
The invention relates to a manufacturing method of LED aluminum substrate V-shaped groove. The method sequentially comprises the steps of aluminum substrate surface treatment; blue gum covering, aluminum substrate shaping; V-CUT cutting, blue gum removing, and the like. According to the invention, when V-CUT cutting is carried out, cutting is carried out by using common FR4 mill. When the mill operates in high speed, high temperature generated by cutting can rapidly melt the blue gum. The molten gum can wrap approximately 2/3 of the V-shaped groove area, and can be hardened and cooled rapidly. Irregular aluminum scraps are condensed on the blue gum, and are prevented from being condensed on aluminum surface of the V-shaped groove. When the blue gun is torn off, the aluminum craps on the blue gum is completely removed, such that the shaped V-shaped groove satisfies a quality standard. The method provided by the invention has the advantages of low cost and easy realization.
Description
Technical field
The present invention relates to PCB manufacturing technology field, be specifically related to the V-type groove processing method on a kind of aluminium base.
Background technology
Because aluminium base aluminium matter belongs to metal material, can not be as the moulding Double-edged milling cutter in V-CUT cutting is made can by run up, large chip removal is dredged and the alcohol type of cooling is successfully got rid of the aluminium bits, use the milling cutter cutting aluminium base V-type groove of normal FR4 to produce high temperature because of cutting, the aluminium bits are dredged without chip area, the high temperature moment that produces on the V-type groove, is caused the quality defect that can't repair with aluminium bits knot---and V cheats burr.Aluminium base therefore of the same trade is made the special-purpose V-CUT cutter of aluminium base that manufacturer all purchases high price, otherwise can't make the V-type groove.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind ofly to be guaranteed under the prerequisite of quality, uses conventional V-CUT cutter to carry out the method for V-type groove processing on aluminium base.
For solving the problems of the technologies described above, the technical scheme that the present invention takes is: a kind of aluminium base V-type groove processing method is characterized in that: be included in the blue glue of aluminium base surface coverage to be processed, then the step of carrying out the processing of V-type groove.
Preferably, before described method covers blue glue, to aluminium base to be processed surface carrying out grinding process.
Concrete, described method comprises that also the V-type groove machines the step of the blue glue of rear removal.
Compared with prior art, the invention has the beneficial effects as follows: the present invention has realized using conventional FR4 V-CUT cutter to make aluminium base V-type groove, has solved the Burr Problem that produces in the V-CUT process, guarantees aluminium base V-type groove crudy, cost is low, easily realizes.
Description of drawings
Fig. 1 is the method for the invention V-type groove machining sketch chart.
The specific embodiment
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing and embodiment, the present invention is explained in further detail.
The disclosed whole flow process of aluminium base V-type groove processing method is: aluminium base surface treatment → cover blue glue → shape molding → V-CUT to cut → remove blue glue → cleaning washing.
Cover before blue glue aluminium base with pin brush Plate grinder polishing aluminium face, strengthen the adhesion of aluminium face and blue glue, and burr foreign material on removing aluminum plate face etc., then press blue glue 2 on aluminium base 1 surface, as shown in Figure 1.Note checking the real situation of blue glue laminated after pressing, can not have bubble to exist.Described blue glue is PCB industry adhesive tape commonly used, for example do not need during gold-plated finger gold-plated place with blue glue anti-golden.
Moulding is the moulding manufacturing process according to client's product demand.Complete shape molding before V-CUT, invest the lip-deep blue glue of aluminium base after need maintenance moulding and do not peel off and space foaming phenomenon.
During the V-CUT cutting, adopt conventional FR4 milling cutter cutting, milling cutter runs up, cutting aluminium layer 1, aluminium bits are taken away by the milling cutter sawtooth is random, saw simultaneously in the cutter cutting process, saw cutter and the cutting of metallic aluminium face produce high temperature (being enough to dissolve tiny aluminium bits), the high-temperature digestion that the blue glue in V-type groove this moment zone is rubbed rapidly, colloidal sol 4 approximately can wrap up sidewall 2/3rds zones (be left 1st/3rd, do not descend aluminium to consider to be worth doing) of V-type groove 3, and it is cooling to harden rapidly, and random aluminium bits condense on blue glue, as shown in Figure 1.
When blue glue is torn, the aluminium bits of knot on blue glue all are eliminated clean, and the V-type groove of moulding meets quality standard.Last cleaning water-washing step is used for aluminium bits, the ashes on the cleaner plate face and removes surface oxidation.
Above-described embodiment is the preferred embodiment of the present invention, and in addition, the present invention can also have other implementations.That is to say, under the prerequisite that does not break away from the present invention's design, within any apparent replacement also should fall into protection scope of the present invention.
