Description
Technical Field
The utility model relates to an electronic product local gilding technical field, concretely relates to local gilding apparatus for producing of product.
Background
The final stage of the packaging of the CPU is to adhere the heat sink or the shielding case to the PCB and Die, wherein Die is the core part of the CPU, and the heat generated by the Die working needs to be transferred to the heat sink through the cover plate or the shielding case, so as to realize the cooling. At present, the industry is basically divided into two processes of brazing and heat-conducting silicone grease bonding, wherein the brazing process has the following requirements: the main raw material of brazing is indium sheet, which has good welding effect with copper and silicon, but the radiating fin generally blocks a layer of nickel metal in order to prevent oxidation, and the indium sheet has poor welding effect with nickel, so a layer of noble metal Au needs to be blocked on the nickel layer, and the welding effect of the gold element and the indium sheet is good. It should be the gold element that is costly and impossible to plate the heat sink in its entirety, so that the gold plating can only be performed in the Die-to-heat sink contact area, i.e. the local plating technique.
