Abstract

The invention discloses rosin scaling powder. The rosin scaling powder comprises, by weight, 10 parts to 20 parts of rosin modified phenolic resin, 5 parts to 10 parts of rosin glyceride, 70 parts to 80 parts of organic solvents, 2 parts to 5 parts of surfactants, 1 part to 3 parts of activators and 1 part to 2 parts of film forming agents, wherein the organic solvents are one kind of ethyl alcohol, propyl alcohol, butanol, acetic ether and butyl acetate, the surfactants are sodium dodecyl benzene sulfonate or fatty glyceride, the activators are one kind of glutaric acid, itaconic acid, o-hydroxybenzoic acid, malic acid and succinic acid, and the film forming agents are nitrocellulose. Residues of the rosin scaling powder are easy to remove, and injuries to the human body and environment pollution can be avoided.

Description

technical field [0001] The invention relates to the technical field of solder, in particular to a rosin flux. Background technique [0002] There are many types of flux, which can be roughly divided into three series: organic, inorganic and resin; resin flux is usually extracted from the secretions of trees, which is a natural product and is not corrosive. Rosin is the representative of this type of flux, so Also known as rosin-based flux; flux is usually a mixture of rosin as the main component, which is an auxiliary material to ensure the smooth progress of the welding process. To achieve the necessary cleanliness, it prevents re-oxidation of the surface during soldering, reduces the surface tension of the solder, improves soldering performance, and the performance of the flux directly affects the quality of electronic products. With the development of the electronics industry and the implementation of the policy of prohibiting the use of Freon, the direction of electroni...
