Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may for example be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; the two components can be directly connected or indirectly connected through an intermediate medium, and the two components can be communicated with each other. The specific meaning of the above terms in the present invention can be understood in specific cases for those skilled in the art.

Referring to fig. 1 and 2, fig. 1 and 2 disclose a FPC heat dissipation structure for a rear camera flash, which includes a main board 1, an FPC board 2, LED lamp beads 3 and a lampshade 4, wherein the LED lamp beads 3 are arranged in the lampshade 4, the LED lamp beads 3 are connected with one end of the FPC board 2, and the other end of the FPC board 2 is connected with the main board 1 through terminals 5; still include heat-conducting piece 6, be located the one end of FPC board 2 of LED lamp pearl 3 below passes through heat-conducting piece 6 with mainboard 1 is connected. To 3 heat dissipation problems of LED lamp pearl, through a heat conduction piece 6 of SMT surface mounting on mainboard 1, contact with FPC board 2, conduct the heat of gathering on FPC board 2 to mainboard 1 to reach the radiating effect.

Preferably, the heat conducting member 6 is made of a metal material.

Preferably, the metal material is a copper alloy. Specifically, metal materials such as aluminum alloy, iron, steel, etc. have poor heat dissipation effects, and are therefore not the optimal choice; the heat conducting member 6 made of copper alloy has the most ideal heat conducting effect and cost performance among a plurality of metal materials, and the heat conducting effect is far lower than the price of metal materials such as gold, silver and the like because the metal materials such as aluminum alloy, iron, steel and the like have the price per se, so that the heat conducting member 6 adopts the copper alloy as the manufacturing material and is the optimal choice.

Preferably, the FPC board further comprises a heat-conducting silicon rubber sheet 7, and the FPC board 2 is connected with the heat-conducting member 6 through the heat-conducting silicon rubber sheet 7; the heat-conducting silica gel is a high-end heat-conducting compound, and can not be solidified, and the risk such as circuit short circuit can be avoided due to the characteristic of no electric conduction; the heat-conducting bonding sealing silicone rubber is a single-component, heat-conducting and room-temperature curing organic silicon bonding sealant; the high-performance elastomer is vulcanized by condensation reaction of water in air to release low molecular weight to cause crosslinking and solidification.
