Abstract

The invention discloses resin type scaling powder which comprises the following ingredients: 5-30 parts of rosin, 4-20 parts of rosin derivative, 40-60 parts of organic solvent, 0.2-2 parts of organic acid, 0.1-5 parts of palmitate and 0.01-0.5 part of benzotriazole. The scaling powder has an excellent solder-aiding effect, is capable of improving the electrical insulating property and expandability of an electric welding product without washing and drying and is convenient in use; and the scaling powder is applicable to automatic wave-soldering, dip soldering and manual soldering of a printed circuit board, and also can be used for carrying out anti-oxidation pre-coating on the leads of whole electronic components of the printed circuit board.

Description

technical field [0001] The invention relates to a flux, in particular to a resin type flux. Background technique [0002] In the production process of printed circuit boards, it needs to be soldered. In order to improve the quality of electric welding, flux is generally used, but the effect of flux in the prior art is not ideal, and after electric welding, it needs to be washed and dried. The operation is cumbersome and the production efficiency is low. Contents of the invention [0003] The present invention is just to overcome the above-mentioned shortcomings, and the technical problem to be solved is to provide a resin-type flux with good fluxing effect. [0004] In order to solve the problems of the technologies described above, the technical scheme adopted in the present invention is as follows: [0005] A kind of resin type soldering flux, it comprises the component of following parts by weight: [0006] [0007] Wherein, as a preferred proportion, a resin type...
