Abstract

The invention provides an efficient antirust heat-resistant chip, comprising three coatings which are sequentially superposed from top to bottom, wherein the three coatings comprise the following raw materials in parts by weight: 45-65 parts of a water-based polyethylene wax emulsion, 25-40 parts of ferric oxide yellow, 5-12 parts of polyacrylic acid, 2-6 parts of aluminum dihydrogen phosphate, 1-3 parts of sodium benzoate, 15-25 parts of activated aluminum oxide, 1-3 parts of magnesium hydrate, 1.5-2.5 parts of hydroxyethyl cellulose, 0.5-1.5 parts of methylbenzotriazole, 0.1-0.5 part of dodecanol ester, 1-2 parts of polydimethylsiloxane and 40-60 parts of deionized water. The coatings have the advantages of rust resistance, flame retardant property and high-temperature resistance.

Description

technical field [0001] The invention relates to the field of semiconductors, in particular to an efficient antirust and high temperature resistant chip. Background technique [0002] The chip in the sensor is a general term for semiconductor component products, which is the carrier of integrated circuits and is divided into wafers. The existing coatings used on chips do not have a good flame-retardant and anti-rust effect, and because most of the existing coatings are epoxy systems, the ether bonds of the epoxy resin are easily broken when exposed to ultraviolet rays , causing the aging of the coating.
