Abstract
The utility model discloses the pressing circuit board of a kind of aluminium base and two-sided FR4 plate, comprise aluminium base and two-sided FR4 plate, described two-sided FR4 plate corner place is provided with via, described aluminium base is provided with blind slot hole I, described blind slot hole I is corresponding with the position of via, is filled with detachable blind slot block in it.The utility model both ensure that the good conductive welding performance of product, can greatly reduce again the fraction defective of product, and circuit board aluminium base and two-sided FR4 being hardened close has actual production and use value.
Description
Technical field
The utility model relates to circuit board technology field, is specifically related to the pressing circuit board of a kind of aluminium base and two-sided FR4 plate.
Background technology
PCB is important electronic unit, is the supporter of electronic devices and components, is the carrier of electronic devices and components electrical connection.As long as there are the electronic devices and components such as integrated circuit, in order to the electric interconnection between them, all PCB will be used.PCB develops into two-sided, multilayer and flexibility from individual layer, and still remains respective development trend.Due to constantly to high accuracy, high density and high reliability future development, continuous reduced volume, reduce cost, improve performance, make PCB in the development engineering of future electronic equipment, still remain powerful vitality.
FR4 plate mechanical performance, dimensional stability, impact resistance, moisture resistance properties are than paper substrate plate hight, and its excellent electrical properties, working temperature is higher, and performance own is affected by environment little.In processing technology, than the glass-fiber-fabric substrate of other resins, there is very large superiority, so be widely used in for two-sided PCB.And aluminium base has good thermal conductivity, electrical insulation properties and machining property due to it, conductive coefficient is greater than 2.0 and extensively adopts aluminium base in the industry.As for both combinations, the fraction defective due to product is too high and cannot ensure the conductive solder performance that product is good, so have also not occurring in conjunction with product of practical significance.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of not only to have been had good conductive solder performance but also can mass-produced aluminium base and two-sided FR4 to have hardened the circuit board closed.
To achieve these goals, the technical solution adopted in the utility model is:
The pressing circuit board of a kind of aluminium base and two-sided FR4 plate, comprise aluminium base and two-sided FR4 plate, it is characterized in that, described two-sided FR4 plate corner place is provided with via, described aluminium base is provided with blind slot hole I, described blind slot hole I is corresponding with the position of via, is filled with detachable blind slot block in it.
Further, described circuit board is also provided with insulating barrier, and described insulating barrier is pressed between aluminium base and two-sided FR4 plate.
Further, described insulating barrier is provided with the blind slot hole II corresponding with blind slot hole site.
The beneficial effects of the utility model: the utility model ensure that the conductive solder performance of board by the blind slot hole on aluminium base and insulating barrier, utilize dismountable blind slot block to ensure board entirety still uniform force in the manufacturing process of routine simultaneously, the quality problem such as appearance pressing plate bursting layering that can not be regular, greatly reduce the fraction defective of product, circuit board aluminium base and two-sided FR4 being hardened close has actual production and use value.
Accompanying drawing explanation
Fig. 1 is the STRUCTURE DECOMPOSITION schematic diagram of the utility model preferred embodiment.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
With reference to Fig. 1, in the present embodiment, the pressing circuit board of a kind of aluminium base and two-sided FR4 plate, comprise the two-sided FR4 plate 2, insulating barrier 6 and the aluminium base 1 that combine successively from top to bottom, described two-sided FR4 plate 2 four jiaos of places all concentrate several vias 3, described aluminium base 1 is provided with four blind slot holes I 4, insulating barrier 6 is provided with four blind slot holes II 7, the position in described blind slot hole I 4 and blind slot hole II 7 is all corresponding with via 3 position on two-sided FR4 plate 2, the blind slot block 5 that what each blind slot hole was all detachable be provided with for filling blind slot hole.In this force fit plate manufacturing process, blind slot block 5 is filled in the sheet deformation that blind slot hole can avoid discontinuity to cause, the blind slot block 6 that in use breaks can ensure the conductive solder performance of this board.
Above better enforcement of the present utility model is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent distortion or replacement are all included in the application's claim limited range.
