Abstract

The invention provides an aromatic lead-free solder paste to aim at solving the problem that leaded solder paste and lead-free solder paste are difficult to distinguish in use and simultaneously improve the air quality in the environment of work sites; the aromatic lead-free solder paste consists of alloy solder powder and soldering flux paste; the soldering flux paste includes solvent, activating agent, film forming agent, tackifier, wetting agent and thixotropic agent, the soldering flux paste also contains high boiling point alcohol compounds with aromatic odor, and the weight of the high boiling point alcohol compounds with aromatic odor accounts for 0.01-50% of the total weight of the soldering flux paste. The aromatic lead-free solder paste of the invention can improve the performance of soldering flux paste, increase the identity of the product, prevent leaded solder paste and lead-free solder paste from being mixed up and strengthen fragrant stimulation to the sense organs of operators who can be exited when smelling aromatic odor; furthermore, the aromatic lead-free solder paste can create a comfortable environment and the surrounding of a production line can give off faint scent.

Description

technical field [0001] The invention belongs to the field of electronic chemicals and relates to a soldering material for electronic printed circuit board assembly, in particular to an aromatic lead-free solder paste. Background technique [0002] At present, domestic electronic information enterprises have the problem of cross-contamination in the process of using lead-free and lead-free solder paste at the same time. In order to prevent the confusion of lead-free and lead-free solder paste, the existing technology is to add perfume or essence to the solder paste to make The paste has a unique smell to be distinguished, but this method only makes the product have a temporary fragrance by spraying or blending. The fragrance of the solder paste will evaporate and disappear as the temperature rises during the reflow process of the circuit board. [0003] In addition, the existing lead-free solder paste used in the soldering and assembly of electronic printed circuit boards con...
