Problems solved by technology

All the carrier boards used in traditional SMT processing are made of metal materials such as aluminum alloy (required for high temperature resistance of reflow furnace and not easy to deform), aluminum alloy is a pure conductor material, when the product attached to the carrier board has static electricity, the carrier board The board touches the machine track, and the machine track is grounded as a whole. The rapid discharge of static electricity will inevitably burn out the electronic integrated circuit, so the aluminum alloy material does not meet the anti-static requirements

Embodiment 1

[0019] see figure 1 , the invention discloses an SMT carrier board, wherein the SMT carrier board is a carbon fiber board 1 .

[0020] Since the carbon fiber board 1 not only has good antistatic performance, but also has good heat conduction, high flatness, and is not easily deformed after frequent use, it is preferable that the SMT carrier board is the carbon fiber board 1 .

[0021] The SMT carrier board provided by the present invention, because the SMT carrier board is a carbon fiber board 1, the carbon fiber board 1 can make the product with static electricity slowly discharge the static electricity on the product through the impedance of the SMT carrier board, avoiding the traditional aluminum alloy pure conductor. SMT carrier board makes static electricity damage electronic products.

Embodiment 2

[0023] In yet another embodiment of the present invention, the SMT carrier board in this embodiment is similar in structure to the SMT carrier board in Embodiment 1, so the similarities will not be repeated, and only the differences will be introduced.

[0024] This embodiment specifically discloses that in the SMT carrier board, the carbon fiber board 1 is composed of glass fiber, high temperature resistant resin and toner, and the toner can make the SMT carrier board into various colors.

[0025] Further, the present invention discloses the mass percentage of each component in the SMT carrier board, the content of glass fiber is 70%, the content of high temperature resistant resin is 25%, and the content of toner is 5%. In this embodiment, the content of toner is Take black for example. And through experiments, the following data are obtained: the color of the SMT carrier board is black, and the density is 1.9g / cm 3 , Bending strength / bending resistance (vertical three-poin...

Abstract

The invention discloses an SMT support plate. The SMT support plate is a carbon fiber plate. According to the SMT support plate provided by the invention, the SMT support plate is the carbon fiber plate which has high anti-static property, so that the problem that the SMT support plate of the conventional aluminum alloy pure conductor causes static damage to an electronic product can be avoided.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to an SMT carrier board. Background technique [0002] As electronic products become smaller and lighter, a large number of integrated circuits appear in electronic products, but integrated circuits have very high requirements for anti-static in the process of processing. All the carrier boards used in traditional SMT processing are made of metal materials such as aluminum alloy (required for high temperature resistance of reflow furnace and not easy to deform), aluminum alloy is a pure conductor material, when the product attached to the carrier board has static electricity, the carrier board The board touches the machine track, and the machine track as a whole is grounded. The rapid discharge of static electricity will inevitably burn out the electronic integrated circuit, so the aluminum alloy material does not meet the anti-static requirements. [0003] Therefore, h...
