NOVELTY - The utility model claims a high-conductivity composite welding rod for chip micro-welding, comprising a welding core body, a welding end, a graphene coating, an anti-corrosion coating, an output end, a silver fibre block, a medicine skin layer, a limiting rod I, a limiting rod II; a protective antibacterial layer and a carbon fibre layer; the right side of the welding core body is provided with a welding end; and the left side of the welding core body is provided with an output end; the outer side of the welding core body is provided with a medicine layer; and the outer surface of the welding core body is provided with a limiting rod one; the outer side of the limiting rod one is provided with a protective antibacterial layer. The high-conductivity composite welding rod for chip micro-welding can be convenient for welding the chip through the welding end set, and the graphene coating can protect the welding end, avoid the damage caused by long-time use, the output end is matched with the silver fibre block; which can make the welding rod have good conductivity, avoid the bad conductive effect of the welding rod in use and affect the subsequent use.
