Abstract
The utility model relates to a double-sided aluminum core circuit board with plughole resin, which mainly comprises an aluminum core board; and the aluminum core board is provided with a through hole in which the plughole resin is arranged, the upper surface and the lower surface of the aluminum core board are respectively provided with an insulation layer, the external surface of the insulation layer is provided with wire layers that are connected through adhesive membranes in a compressing manner, through holes are arranged in each wire layer corresponding to the center of the plughole resin, and the through hole is internally provided with a metal layer connecting with the upper wire layer and the lower wire layer; the upper surface and the lower surface of the aluminum core board are sequentially provided with the insulation layer and two wire layers, and the two wire layers are connected through the metal layer, so that electronic components can be pasted or inserted at the two side surfaces of the circuit board simultaneously; the circuit board takes aluminum as a substrate, thus having good radiation property, all the layers are connected through the adhesive membranes in the compressing manner, so that the heat conductive coefficient of the circuit board is high, the radiation effect is good, the peel strength is improved; and the plughole resin is arranged between the metal layer and the aluminum core board, so that the circuit board has good insulation property, and the use stability of the circuit board is further improved.
Description
Technical field
The utility model relates to the integrated circuit board field, especially a kind of two-sided aluminum core line road plate with plug socket resin.
Background technology
Metal base circuit board has excellent thermal diffusivity, electrical property, electromagnetic wave shielding and favorable mechanical processing characteristics and is widely used in power hybrid integrated circuit, Switching Power Supply, automobile, communication electronic equipment; LED illumination etc.; Particularly at the LED lighting field, owing to LED brightness height, energy-efficient, environmental protection; High speed development in recent years also is that emphasis encourages to help development energy-conserving and environment-protective industry during the country 12.Present stage, metal base circuit board all was single-sided structure; And can only use and show and mount components and parts; Particularly, when needing the two sides simultaneously luminous, all adopt the metal base circuit board of two single faces to use with back-to-back combining form like large-scale colored curtain wall, LED at the LED lighting field; Increased use cost, and security reliability is low.
The utility model content
The purpose of the utility model is to provide a kind of with low cost for the deficiency that solves above-mentioned technology, but and the two-sided aluminum core line road plate of the good band plug socket resin of serviceability is used on the two sides simultaneously.
In order to achieve the above object, the two-sided aluminum core line road plate of the band plug socket resin that the utility model designed, it mainly comprises the aluminium central layer; On the aluminium central layer, be provided with the hole of perforation, in the hole, be provided with plug socket resin, be equipped with insulating barrier at aluminium central layer upper and lower surfaces; Outer surface at insulating barrier is provided with line layer; Each layer connects through the adhesive film pressing, and the center with respect to plug socket resin on each layer is provided with through hole, is provided with at through-hole wall to connect the metal level of line layer up and down.This design feature is: the line layer on aluminium central layer two sides connects through metal level; The wiring board two sides can be mounted or the plug-in mounting electronic devices and components simultaneously; And between metal level and aluminium central layer, being provided with plug socket resin, insulation property are better, further improved the stability in use of wiring board.
The two-sided aluminum core line road plate of the resulting band plug socket resin of the utility model; Be provided with insulating barrier and line layer successively at aluminium central layer upper and lower surfaces; And connect two line layers through metal level; Can realize that the wiring board two sides mount simultaneously or the plug-in mounting electronic devices and components, instead is used the combining form use back-to-back of two single face wiring boards.This wiring board adopts aluminium as matrix, perfect heat-dissipating.Connect through the adhesive film pressing between each structure sheaf simultaneously, make the conductive coefficient of wiring board high, good heat dissipation effect, and improved peel strength.And between metal level and aluminium central layer, be provided with plug socket resin, insulation property are better, further improved the stability in use of wiring board.In addition, produce and use this wiring board, cost is relatively low.
Description of drawings
