Abstract

The invention relates to the technical field of cleaning agents, in particular to a phosphorus-free and nitrogen-free semiconductor packaging cleaning agent which comprises 1-phenoxy-2-propanol, an inorganic saponifying agent, a bubble-free emulsifier, a pH regulator and deionized water, the mass ratio of the inorganic saponifying agent to the pH regulator is (3-7):(4.5-10.5), the mass ratio of the 1-phenoxy-2-propanol to the inorganic saponifying agent to the bubble-free emulsifier is (20-65):(3-7):(20-35), and the conductivity of the deionized water is less than 5 [mu]s. The 1-phenoxy-2-propanol, the inorganic saponifying agent, the bubble-free emulsifier and the pH regulator have a synergistic effect, so that the semiconductor packaging cleaning agent has the advantages of environment friendliness and high cleaning efficiency.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to a phosphorus- and nitrogen-free semiconductor package cleaning agent. Background technique [0002] As the foundation and support for the development of the modern electronics industry, semiconductors are more and more widely used and selected materials in the electronics industry. However, with the continuous improvement of the integration, high precision and high reliability requirements of semiconductor products, the attention and reliability of the semiconductor package cleaning industry are also getting higher and higher. Flux and solder paste are usually used as soldering auxiliary materials in the semiconductor device packaging process, and these auxiliary materials will have some residues during the soldering process. Residues and pollutants have complex components, and there is a risk of corrosion to devices under the action of air oxidation and moisture, especi...
