Problems solved by technology

At present, the materials used for SMD brackets in the industry are generally copper plates made of brass. The copper plates have good electrical conductivity and can meet the luminous performance of LED lights and other light-emitting devices. However, the cost of copper is very high, about 50-60 Yuan / kg, making the production cost of patch brackets extremely expensive

Abstract

The invention relates to a paster type support. The paster type support is prepared by components as follows according to mass parts, C, 3.2-4.6 parts; Mn, 17-21 parts; P, 9.1-10.8 parts; S, 3.4-4.9 parts; and Al, 57-68 parts. The paster type support is prepared by the components according to the mass parts, thickness of the prepared paster type support is low to 0.2mm, under the condition of the small thickness, excellent conductivity and relatively good extension performance are maintained, the surface of the paster type support can be relatively smooth, and the reflection effect for LED light can be further enhanced. A traditional paster type support is prepared by brass, resistance of brass is 1.75*10<-8>, resistance of aluminum is 2.83*10<-8>, resistance of iron is 9.78*10<-8>, the smaller the resistance, the higher the conductivity. The paster type support is advantaged in that through selecting the aluminum of which conductivity is close to conductivity of the copper as a main raw material to prepare the paster type support, on the condition that conductivity is close or slightly decreases, production cost is reduced.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a patch-type stent and a preparation method thereof. Background technique [0002] With the development of science and technology, LED lighting technology has become increasingly mature and developed, and LED has become a new type of light source that is widely used. The preparation of LED chips into LED lamps with actual lighting effects requires a relatively complicated process, in which the LED chips must be mounted on a bracket, which is the LED lamp patch bracket. Of course, it can be understood that the patch bracket not only refers to the patch bracket applied to the LED, but also applies to the patch bracket used in other light emitting devices. [0003] The performance of the SMD bracket plays an important role in the luminous performance of LED lights and other light-emitting devices, and will affect the conductivity, luminous brightness, and service life of LED ligh...
