Abstract
The utility model discloses a high-pressure-resisting high-performance aluminum substrate used for printing. A single face or two faces of the aluminum substrate is provided with a plurality of protruding edges crossed with each other and formed through extrusion. Pits are formed between the crossed protruding edges. According to the utility model, since the regular pits are formed in the surface of the aluminum substrate through extrusion, forces for combining with a prepreg in all directions are increased, the close combination of the aluminum substrate and the insulating film is facilitated effectively and the high-pressure-resisting performance of the aluminum substrate used for printing is improved substantially. And the aluminum substrate used for printing is simple in technique and low in cost.
Description
Technical field
The utility model relates to a kind of printing aluminium base.
Background technology
Along with the universal and extensive use of electronic product, the technology that adopts metal substrate to make printed substrate is also being constantly updated and development; For example, be development and the demand that satisfies various electron stream products, printed substrate based on the aluminium base making, the even multiaspect aluminium base development from the single-sided aluminum-base plate to double-face aluminium substrate, namely at the monolateral or interlayer of former printed wire panel products, aluminium sheet being set increases radiating effect, to improve the useful life of electronic product; Therefore the unfailing performance of aluminium base after insulating cement is combined is extremely important, and existing aluminium base surface is bonding through brush coating water, and technique is simple, but the high voltage performance of printed wire board finished product is low.
The utility model content
The utility model provides a kind of high voltage performance good printing aluminium base.
Realize the printing aluminium base of the utility model purpose, the aluminium sheet single or double of described aluminium base squeeze out many cross one another protruding stupefied, form pit between described intersection protruding stupefied; The protruding stupefied density of described aluminium sheet surrounding that is distributed in of described intersection is greater than the density of centre.
The beneficial effects of the utility model are as follows:
Printing aluminium base of the present utility model due to the pit to the surface of aluminium sheet extruding formation rule, has increased on all directions the adhesion with prepreg, effectively promoted combining closely of aluminium sheet and insulation film, the finished product high voltage performance improves greatly, and technique is simple, and cost is low.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Embodiment: as shown in Fig. 1, printing aluminium base of the present utility model, the single or double of the aluminium sheet 3 of described aluminium base squeeze out many cross one another protruding stupefied 1, described intersection protruding stupefied 1 between form pit 2; Protruding stupefied 1 of described intersection is distributed in the density of described aluminium sheet 3 surroundings greater than the density of centre.
Printing aluminium base of the present utility model pushes the pit 2 of formation rule due to the table to aluminium sheet 3, increased on all directions the adhesion with prepreg, effectively promoted combining closely of aluminium sheet and insulation film, the finished product high voltage performance improves greatly, and technique is simple, and cost is low.
Above-described is only preferred implementation of the present utility model, should be understood that for a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement, these can not affect effect and practical applicability that the utility model is implemented.
Claims (1)
1. printing aluminium base is characterized in that: the aluminium sheet single or double of described aluminium base squeeze out many cross one another protruding stupefied, form pit between described intersection protruding stupefied; The protruding stupefied density of described aluminium sheet surrounding that is distributed in of described intersection is greater than the density of centre.
