Embodiment 1

[0033] A high-stability flux paste is composed of: 32% of compound rosin, 10% of compound thixotropic agent, 12% of compound activator, 40% of compound organic solvent and 6% of antioxidant.

[0034] The compounded rosin is: Japan Arakawa KE604 rosin and RHR-101 water white rosin are compounded in a mass ratio of 3:2. Weigh the above two kinds of rosin in proportion, first move RHR-101 water white rosin into the bottom of the stainless steel pot, then add KE604 rosin, use an electric heating furnace to heat, after RHR-101 water white rosin is melted, stir with a glass rod, KE604 rosin It begins to melt, and the solid rosin gradually transforms into a liquid state. After the rosin is completely dissolved, it is fully stirred, and the water is evaporated to form a transparent and uniform rosin liquid. The residue was removed with a filter, and the compound rosin A-1 with a new structure was obtained after cooling.

[0035] The compound thixotropic agent is to compound ST thixot...

Embodiment 2

[0041] A high-stability flux paste is composed of: 37% of compound rosin, 5% of compound thixotropic agent, 10% of compound active agent, 43% of compound organic solvent, and 5% of antioxidant.

[0042] The compounded rosin is obtained by compounding domestic HM604 rosin and AX-80 water white rosin in a mass ratio of 4:3. Weigh two kinds of rosin in proportion, first move AX-80 water white rosin into the bottom of the stainless steel pot, and then add HM604 rosin. Use an electric heating furnace for heating. After AX-80 water white rosin is melted, stir with a glass rod. HM604 rosin begins to melt, and the solid rosin gradually turns into a liquid state. After the rosin is completely dissolved, it is fully stirred and the water is evaporated to form a transparent and uniform rosin. The rosin liquid was used to remove the residue with a filter, and after cooling, the compound rosin A-2 with a new structure was obtained.

[0043] The compound thixotropic agent is obtained by co...

Embodiment 3

[0049] A high-stability flux paste is composed of: 40 percent of compound rosin, 9 percent of compound thixotropic agent, 5 percent of compound active agent, 45 percent of compound organic solvent, and 1 percent of antioxidant.

[0050] The compounded rosin is obtained by compounding domestic AR-125 rosin and AX-E rosin in a mass ratio of 4:3. Weigh two kinds of rosin in proportion, first move AX-E rosin into the bottom of the stainless steel pot, and then add AR-125 rosin. Use an electric heating furnace for heating. After the AX-E rosin is melted, stir with a glass rod. The AR-125 rosin begins to melt, and the solid rosin gradually transforms into a liquid state. After the rosin is completely dissolved, it is fully stirred and the water is evaporated to form a transparent uniform. The rosin liquid was used to remove the residue with a filter, and after cooling, the compound rosin A-3 with a new structure was obtained.

Abstract

The invention discloses high-stability flux paste and a preparation method thereof. The flux paste comprises 30-45 wt.% of compound rosin, 3-10 wt.% of a compound thixotropic agent, 3-12 wt.% of a compound active agent, 30-50 wt.% of a compound organic solvent and 1-6 wt.% of an antioxidant. According to the preparation method of the flux paste, the compatibility and dispersity of substances in a system can be improved, the high activity of the flux paste is kept, and meanwhile the stability is improved. The high-stability flux paste prepared from the materials and welding powder are prepared into solder paste, and the storage stability, the printing stability and the welding performance of the high-stability flux paste are better than those of other solder paste.

Description

technical field [0001] The invention relates to the technical field of flux paste for solder paste and a preparation method. Background technique [0002] Soldering paste is a kind of flux, because it is paste-like at room temperature, so it is called soldering paste. Soldering paste is prepared from organic acids, organic amines, rosin resins, organic amides, organic solvents, tackifiers, antioxidants, thixotropic agents and other organic compounds. Different manufacturers have different types of soldering paste formulations and preparation methods. different. Soldering paste is the main raw material for preparing solder paste. Solder paste is gray paste, which is a new type of soldering material that came into being with SMT. It is a paste formed by mixing flux paste and solder powder in a volume ratio of 1:1 (or a mass ratio of 1:9). The mixture is mainly used for the welding of electronic components such as PCB surface resistance, capacitors and ICs in the SMT industr...
