Description
Technical Field
The invention relates to B23K, in particular to a high-activity water-washing scaling powder and a preparation process thereof.
Background
The soldering flux is an auxiliary agent for removing metal oxide on the surface of a bonding pad in a welding process and promoting welding, and after the welding is finished, residual soldering flux such as water cleaning type soldering flux and the like needs to be removed through an oil-based or water-based cleaning agent, and the problems that the residual soldering flux is more after welding due to the fact that the water cleaning type soldering flux comprises resin with high content such as rosin and the like exist.
CN109676284a discloses a soldering paste and a method for manufacturing the same. The paste formulation comprises: 8-15% of rosin, a solvent, a thixotropic agent, organic acid, a surfactant and organic amine, and has the advantages of low reflux temperature, less flux paste residues, strong activity, low corrosion and capability of effectively improving the reliability of chip packaging.
The soldering paste has the advantages that the soldering paste adopts low rosin content, so that most of the soldering paste is volatilized in the reflow process, the amount of residues is reduced, the residues are difficult to clean rapidly by using water, and the current soldering paste is difficult to promote the formation of neat and smooth welding spots.
Disclosure of Invention
In order to solve the above problems, the first aspect of the present invention provides a high-activity water-washed flux, which is prepared from the following raw materials in percentage by weight: 8-15 wt% of active agent, 7-12 wt% of thickener and the balance of solvent.
In the welding process, the surface of a base material such as Cu, ni, au, pb is provided with an oxide layer to influence the formation and wetting of welding spots, so that an active agent is needed to remove the oxide layer to improve the welding activity, and the inventor finds that when a chain acid with a proper carboxyl number is added, the welding activity can be promoted, the wettability of a melt in the welding process can be promoted, but when the adhesive is used for low-temperature welding, the effect of the chain carboxylic acid is softer and the activity is poorer. In one embodiment, the active agent comprises a chain acid having a number of carboxyl groups ranging from 2 to 5. Preferably, the weight ratio of the chain acid having 2 to 3 carboxyl groups to the chain acid having 4 to 5 carboxyl groups is (2 to 6): 1. the chain acid has 10 or less carbon atoms. Examples of chain acids include, but are not limited to, oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, suberic acid, pimelic acid, citric acid, tricarballylic acid, N-hydroxyethyl ethylamine triacetic acid, ethylenediamine tetraacetic acid, diethylenetriamine pentaacetic acid.
The inventor finds that when the thickening agent is obtained by adding acid with a certain carboxyl number and the nitrogenous heterocyclic compound through an acid-base neutralization mode, compared with the method of separately adding polybasic acid and the nitrogenous heterocyclic compound, the thickening agent can effectively promote the activity of low-temperature welding when the thickening agent acts with an active agent, reduce the melting and balling of a melt in the welding process, and promote the wetting of the melt on the surface of a substrate. The inventor discovers that the thickener provided by the invention can also promote the residual cosolvent in welding to be quickly cleaned by water, so that a clean, flat and smooth welding spot is obtained. In one embodiment, the thickener is prepared from a polyacid and a nitrogen-containing heterocyclic compound by acid-base neutralization.
The inventor finds that the thickening agent obtained by using polybasic acid with the carboxyl number of 2-4 contains redundant carboxylate radicals, so that the low-temperature welding activity of the active agent is further promoted, the compatibility with the active agent is also promoted, and the welding residues are promoted to be quickly cleaned by water. In one embodiment, the polyacid has a carboxyl number of 2 to 4 and the polyacid has 10 or less carbon atoms. Examples of the acid include malic acid, fumaric acid, adipic acid, tartaric acid, and citric acid.
In addition, the inventors have found that it is necessary to control the structure of the nitrogen-containing heterocyclic compound, particularly, to use a structure containing an electron withdrawing group such as a hydroxyl group, which promotes compatibility of a thickener with a relatively low water-soluble substance such as a rosin derivative or a terpene oil in a solvent, promotes water solubility and wetting uniformity, and that it is difficult to form a homogeneous phase with a flux to affect wetting effect even when an antimony-containing solder is used, if an alkylamine such as triethanolamine is used for the acid-base neutralization of the resulting thickener. In one embodiment, the nitrogen-containing heterocyclic compound is at least one selected from the group consisting of imidazoles, pyridines, pyrazoles, quinolines.
In one embodiment, the substituents of the nitrogen-containing heterocyclic compound include at least one of hydroxyl, carboxyl, carbonyl, and ester groups. Examples thereof include 4-hydroxypyridine, 2-carboxypyridine, 2-methyl-4-carboxypyridine, 3-carboxypyrazole, imidazole-1-carboxylic acid, 1- (2-hydroxyethyl) imidazole, and 1-hydroxypyrazole.
In one embodiment, the molar ratio of the fatty acid to the nitrogen-containing heterocyclic compound is (0.8 to 1.1): 1, there may be mentioned 0.8: 1. 0.82: 1. 0.85: 1. 0.88: 1. 0.9: 1. 0.95: 1. 0.99: 1.1:1. 1.05: 1. 1.1:1.
the salt obtained by neutralizing the acid and alkali with the main components of the thickener of the invention, which is mainly obtained by neutralizing the acid and alkali with the main components of carboxyl and amino, can be obtained by melting reaction without limitation or solution reaction in water which is well known in the art, wherein the reaction is reversible, the obtained salt can also obtain a small amount of acid and nitrogen-containing heterocycle in water, and the acid-base neutralization is carried out in inert gas atmosphere such as nitrogen, argon and the like. In one embodiment, the thickener is prepared by a melt reaction and/or a solution reaction.
In one embodiment, the melt reaction is a melt mixing of the polyacid and the nitrogen-containing heterocyclic compound at 200-220 ℃ and cooling.
In one embodiment, the solution reaction is obtained by adding polybasic acid and nitrogen-containing heterocyclic compound into water, reacting at 45-60 ℃ and drying. Wherein during the drying process, salt crystallization can be observed along with evaporation and cooling of water, and the salt is obtained by filtration.
In order to reduce the precipitation of the active agent in the welding process and promote the dissolution, the inventor adopts rosin derivatives, terpene oil and alcohol ether to jointly adjust the compatibility and dispersion of the soldering flux in the solder, reduce corrosion and promote the obtainment of a flat and smooth welding spot. In one embodiment, the solvent comprises one or more of rosin derivatives, terpene oils, alcohol ethers, alkyl alcohols. Preferably rosin derivatives, terpene oils, alcohol ethers, in a weight ratio of 1: (0.1-0.3): (0.3-0.5).
Examples of rosin derivatives include, but are not limited to, hydrogenated rosin, disproportionated rosin, hydrogenated rosin alcohol; examples of terpene oils include, but are not limited to, eucalyptus oil, pine needle oil, lemon oil, cypress oil, turpentine, terpineol; examples of alcohol ethers include, but are not limited to, ethylene glycol monophenyl ether, diethylene glycol methyl ether, diethylene glycol monobutyl ether, dipropylene glycol monobutyl ether, tetraethylene glycol monomethyl ether.
In one embodiment, the raw materials for preparing the soldering flux further comprise 1-4wt% of surfactant. The surfactant is not particularly limited in the present invention, and examples thereof include isooctanol polyoxyethylene ether, polyoxyethylene sorbitan fatty acid ester, dodecylbenzene sulfonate, and alkylphenol polyoxyethylene ether, preferably isooctanol polyoxyethylene ether, polyoxyethylene sorbitan fatty acid ester, and alkylphenol polyoxyethylene ether.
The second aspect of the invention provides a preparation process of the high-activity water-washing scaling powder, which comprises the following steps: and mixing the raw materials for preparing the soldering flux at 110-170 ℃ and cooling to obtain the soldering flux. The addition temperature of the feedstock of the present invention may be determined by the boiling point, e.g., a low boiling point feedstock such as propylene glycol may be added below the boiling point.
