Abstract
The utility model relates to a copper base copper clad laminate drilling copper basilar part drapes over one's shoulders lamination at peak structure is improved, including the range upon range of smooth aluminum plate who is in the same place, paper apron, paper gasket board and copper base plate four layers plate body, the range upon range of order top -down of this four layers plate body is in proper order: paper apron + copper base plate + light aluminum plate + paper gasket board. It adopt to fill up the operation of light aluminum plate, stacks up light aluminum plate, paper apron, paper gasket board with range upon range of mode in the copper substrate surface promptly before drilling, can effectively improve the problem that copper base copper clad laminate drilling copper basilar part draped over one's shoulders the peak to can retrieve after light aluminum plate uses up, can not increase the material cost, consequently not only improve production efficiency but also practiced thrift the cost.
Description
Technical field
The utility model belongs to printed wiring board manufacture technology field, is specifically related to one and improves copper baseThe laminate structure of copper-clad laminate (abbreviation copper base) boring copper basal part peak.
Background technology
Along with the fast development of current electron trade, the competition in industry is more and more fierce, major partHigh-end customer is all towards high-power plate development, and copper base generally all can be served as the first-selection of high-power plateMaterial, high because copper base has density, the hot bearing capacity of substrate self is strong, heat radiation, heat conduction effectThe feature that fruit is good. But copper base can cause copper basal part to have peak in Drilling operation process, and drapes over one's shouldersPeak must use abrasive band could grind totally, and after nog plate, peak is very easily rolled in hole, is difficult to cleaning,Waste time and energy. In industry, generally all can select diamond coating to bore to chew for solution boring peak problem addsWork, to reduce peak, but diamond coating bores that to chew cost high, and the 6-7 chewing for common brill is doubly.
Utility model content
For the deficiency of above-mentioned prior art, the utility model provides one can effectively improve copperThe laminate structure of base copper-clad laminate boring copper basal part peak.
The purpose of this utility model is achieved by the following technical programs:
A laminate structure of improving copper base copper-clad laminate boring copper basal part peak, comprises layerThe light aluminium sheet, paper cover plate, Paper baseplate and the copper base four laminate bodies that stack, this four laminates bodyLamination order is followed successively by from top to bottom: paper cover plate+copper base+light aluminium sheet+Paper baseplate.
Further, the thickness of described smooth aluminium sheet is 0.6mm.
Compared with prior art, the beneficial effects of the utility model are: the utility model adopts pad lightAluminium sheet operation, before boring in copper base surface with stacked mode pad glazing aluminium sheet, paper cover plate,Paper baseplate, can effectively improve the problem of copper base copper-clad laminate boring copper basal part peak, andAfter light aluminium sheet is finished, can reclaim, can not increase Material Cost, therefore not only improved production efficiency but alsoSave cost.
Brief description of the drawings
Fig. 1 is copper base boring laminate structure schematic diagram in the utility model.
Detailed description of the invention
The embodiment providing below in conjunction with accompanying drawing does further to say in detail to the utility modelBright.
As shown in Figure 1, a kind ofly improve the folded of copper base copper-clad laminate boring copper basal part peakPlate structure, comprises light aluminium sheet 1 stacked together, paper cover plate 2, Paper baseplate 3 and copper base 4 fourLaminate body, the lamination order of this four laminates body is followed successively by from top to bottom: paper cover plate 2+ copper base 4+ lightAluminium sheet 1+ Paper baseplate 3. Preferably, the thickness of light aluminium sheet is 0.6mm.
Principle of the present utility model be before boring in copper base surface with stacked mode pad glazing aluminiumPlate, paper cover plate and Paper baseplate, while boring like this, can effectively improve copper base copper basal part peakProblem.
Claims (2)
1. improve a laminate structure for copper base copper-clad laminate boring copper basal part peak, its spyLevy and be, comprise light aluminium sheet stacked together, paper cover plate, Paper baseplate and copper base four laminate bodies,The lamination order of this four laminates body is followed successively by from top to bottom: paper cover plate+copper base+light aluminium sheet+paper washerPlate.
2. one is improved copper base copper-clad laminate boring copper basal part and is draped over one's shoulders according to claim 1The laminate structure at peak, is characterized in that: the thickness of described smooth aluminium sheet is 0.6mm.
