Problems solved by technology

In the prior art, the flux containing 1-2% rosin is generally used. In order to ensure the activity of the flux, the enterprise will increase the use of other activators, which will cause the problem of low insulation resistance after welding and the risk of leakage; At the same time, when the general flux is used, because its solvent is alcohol, it is very volatile, which seriously affects the working environment and causes certain harm to the health of the staff.

Embodiment Construction

[0008] The invention provides a new type of flux, whose working principle is to add diethylene glycol monobutyl ether and 3-3.5% modified rosin to the flux to improve the activity of the flux, protect the production environment and ensure The health of the staff.

[0009] A new type of flux, calculated by content percentage, it includes the following components:

[0010]

[0011] Process steps:

[0012] 1. Add the above raw materials into the reaction kettle according to the content ratio;

[0013] 2. Stir for 2-3 hours to fully dissolve the raw materials;

[0014] 3. Let stand for half an hour, filter and pack the product.

[0015] Through the above method, a new type of flux provided by the present invention can improve the activity of flux and protect the production environment by adding diethylene glycol monobutyl ether and 3-3.5% modified rosin to the flux. and ensure the health of staff.

[0016] What is described above is only a preferred embodiment of a novel s...

Abstract

The invention discloses novel soldering flux. The novel soldering flux comprises succinic acid, malonic acid, salicylic acid, triethanolamine, benzotriazole, three hydroxy stearic acid glyceride, oleyl alcohol polyvinyl chloride ether, phenyl glycidyl ether, modified rosin and diethylene glycol monobutyl ether. The purposes of improving the activity of the soldering flux, protecting production environments and guaranteeing the body health of workers are achieved.

Description

technical field [0001] The invention relates to the technical field of electronic welding materials, in particular to a novel flux. Background technique [0002] With the continuous development of electronic technology and the increasing popularity of integrated circuit applications, flux plays an increasingly important role in the electronics industry and related industries. In the prior art, the flux containing 1-2% rosin is generally used. In order to ensure the activity of the flux, the enterprise will increase the use of other activators, which will cause the problem of low insulation resistance after welding and the risk of leakage; Simultaneously general soldering flux is in use, because its solvent is alcohol, and volatility is very strong, has had a strong impact on working environment, and the health of staff is caused certain harm. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention proposes a new t...
