Abstract

The invention discloses a preparation method and application of a surface treatment coating for a ceramic soldering tin head, relates to the technical field of tin soldering of electronic and electrical products, aims to solve the problems of high cost, short service life and difficult maintenance in the prior art, and adopts the technical scheme that the preparation method comprises the following steps: reacting silver salt and gold trichloride with [C19H29COOS] to obtain sulfurized rosin salt; adding silver oxide, silver chloride, a dispersing agent, an adhesive and a plasticizer into the sulfurized rosin salt to obtain the coating, wherein the preparation process, toxic and harmful organic solvents are not used, the technology is environment-friendly, and the physical and psychological health of workers can be protected; and after the coating is sintered, a compact and non-oxidized metal layer can be formed on the surface of the ceramic soldering tin head, and therefore, the situation that soldering capacity is reduced due to oxidation of the soldering tin head is avoided.

Description

technical field [0001] The invention relates to the technical field of tin welding of electronic and electrical products, in particular to a ceramic solder tip surface treatment coating, a preparation method and the application of the coating on a ceramic solder tip. Background technique [0002] Solder is an important industrial raw material for connecting electronic components in welding lines. It is a solder with a low melting point, mainly referring to solder made of tin-based alloys. The production method of solder is to make an ingot by melting method first, and then process it into a material by pressure. [0003] Traditional tin welding of electronic and electrical products is achieved by metal soldering tip tools. However, due to the long-term high-temperature working state (250-350° C.) of the metal soldering tip during use. The metal soldering tip is easy to oxidize and turn black, and the soldering ability decreases with the increase of the oxidation degree of ...
