The embodiment of the present invention provides a kind of electronic building brick, including heat generating member and substrate, the heat generating member and the substrate stack Folded to set, the substrate includes the first face and the second face being oppositely arranged, wherein the first of the substrate facing to the heating Part;Be provided with metal-cored and at least one heat dissipation channel in the substrate, it is described it is metal-cored be connected with least one heat dissipation channel, Heat-conducting medium is filled with each heat dissipation channel, the heat that the heat generating member is produced can be along along described metal-cored and heat dissipation channel Heat-conducting medium, conducted from the first face of the substrate to the second face of the substrate.

The embodiment of the present invention is applied to any electronic building brick with radiating requirements, and be particularly suitable for use in great-power electronic group Part.

For example, with it is current in time bitcom it is prevailing, increasing user is by mobile phone or notebook computer Taken pictures, imaged or live Deng electronic equipment, the frequency of use of camera is more and more frequent, time of work is also increasingly It is long.Therefore, CCD camera assembly needs good heat dispersion.

For another example electronic equipment is in long-term use or charging, battery-heating is more serious, therefore, and battery component needs Good heat dispersion.

It can be seen that, the electronic building brick in the embodiment of the present invention can be camera module or battery modules, can be with It is other high-power heat generating member modules.For camera module, the heat generating member in the embodiment of the present invention can be chip, core Camera lens can be stacked with piece;For battery modules, the heating in the embodiment of the present invention can be just battery and chip.

To more fully understand the embodiment of the present invention, it is specifically described below so that electronic building brick is camera module as an example.

As shown in Figures 1 to 4, the embodiment of the present invention provides a kind of camera module, including camera lens 1, chip 2 and substrate 3, Camera lens 1, chip 2 and substrate 3 stack gradually setting, and substrate 3 includes the first face 31 and the second face 32 being oppositely arranged, wherein substrate 3 the first face 31 is towards chip 2;

Be provided with metal-cored 33 and at least one heat dissipation channel 34 in substrate 3, metal-cored 33 with least one heat dissipation channel 34 connections, are filled with heat-conducting medium in each heat dissipation channel 34, and the heat that chip 2 is produced can be along metal-cored 33 and heat dissipation channel Heat-conducting medium in 34, conducts to the second face 32 of substrate 3 from the first face of substrate 3.

In the embodiment of the present invention, printed circuit board (PCB) (PCB, Printed of the prior art are replaced using substrate 3 Circuit Board), the electric connection with chip 2 is realized by substrate 3.Substrate 3 in addition to being provided with metal-cored 33, its It is remaining to be partially filled with the base material such as resin.

Wherein, metal-cored 33 can be good metal-cored of the electric conductivities such as aluminium core or copper core, and metal-cored 33 in substrate 3 It is integral, based on the layout requirements of substrate 3, the window at interval can be set on metal-cored 33.Metal-cored 33 thickness can Flexibly to set according to stacking space, under conditions of meeting and stacking space, can suitably select that thickness is larger metal-cored 33.

In addition, should set the circuit 35 of electron-donating connection in substrate 3, circuit 35 should be arranged in base material, circuit 35 Layout can flexibly be set according to the need for electric connection.

In general, circuit 35 can be set in metal-cored 33 both sides up and down, metal-cored 33 can also be positioned only at Top, the quantity of circuit 35 can also differentiation.Also just say, be reference with metal-cored 33, the circuit close to the side of chip 2 is minimum It can be one layer, the circuit away from the side of chip 2 can be at least zero layer.

As shown in Figure 1 to Figure 2, when only setting circuit 35 in metal-cored 33 top, because metal-cored 33 lower sections do not have Circuit 35, therefore, metal-cored 33 lower section need not fill base material, so, the second face that metal-cored 33 side wall can be with substrate 3 32 is concordant, i.e., metal-cored 33 side wall is exposed to the second face 32 of substrate 3.

Based on the set-up mode, because metal-cored 33 exposed side walls can serve as radiating surface, therefore can be only in metal The top of core 33 sets heat dissipation channel 34, that is to say, that at least one heat dissipation channel 34 extends to gold from the first face 31 of substrate 3 Belong to core 33.
