Abstract

A metal oxide slurry for making capillary structure in a vapor chamber, which contains cuprous oxide powder, polymer and organic solvent. The colloid formed by mixing the polymer and the organic solvent can be used to uniformly disperse and suspend the cuprous oxide powder to form a metal oxide slurry. Wherein, the metal oxide slurry can volatilize the organic solvent through the heating process, and burn off the polymer through the baking process. Laying the metal oxide paste in the groove of a metal substrate by stencil printing, screen printing or dispensing to make the capillary structure of the vapor chamber, using the metal oxide paste to make the capillary structure can Increase the mass production efficiency of the vapor chamber and improve the mass production yield of the vapor chamber product.

Description

technical field [0001] A metal oxide slurry, especially a metal oxide slurry with a continuous and porous capillary structure used in the manufacture of a vapor chamber. Background technique [0002] The conventional manufacturing method of the vapor chamber is to etch the sheet-shaped copper substrate, lay copper screen mesh (Copper Screen Mesh) or braided mesh (Copper Woven Mesh) on the copper substrate, press and combine them with graphite jigs Sintering at high temperature to form a capillary structure on the surface of the groove of the copper substrate, and then welding the copper substrate with the groove in the groove to form the air channel cavity. Further processing such as sealing, water injection, vacuuming, etc., to make a Vapor Chamber or Heat Pipe Plate with a capillary structure. [0003] The screen mesh (Screen Mesh) material used as the capillary structure of the vapor chamber is a large piece of copper mesh woven with thin copper wires. In actual applica...
