Problems solved by technology

Therefore, the welding work should not be sloppy, otherwise it is easy to cause poor contact due to false welding, or the welding surface is easy to break
Careless soldering will also cause the copper foil of the circuit electrode to fall off or even destroy the external package of the component or the insulation between the internal electrodes, which will affect the quality of the component

Abstract

The invention discloses efficient electronic circuit welding paste. The welding paste is made of, by weight, 2-6 parts of itaconic acid, 7-9 parts of thickening agents of polyamide wax type, 1.5-3 parts of diethylene glycol mono-hexyl ether, 6-10 parts of hydrogenated rosin, 2-5 parts of cetane-based ammonium bromide, 3-9 parts of alkylphenol polyoxyethylene ether, 5-7 parts of hydrochloride, 1-4 parts of triazole, 0.5-1 part of antioxygen, 7-10 parts of diethylene glycol propyl ether, 2.5-6 parts of tartaric acid, 6-7 parts of hydroquinone, 1.3-5 parts of diethylene glycol, 4-5 parts of flogopite,tertiary butyl 0.5-2 parts of ferromanganese and 6-11 parts of 2-tertiary butyl hydrochinone. The welding paste has the advantages that the welding paste used in an electronic circuit is good in welding quality, little in residue and easy to clean, meanwhile, the welding paste has the inoxidizability and the rheological property, and the safety and environmental protection are achieved.

Description

technical field [0001] The invention relates to a high-efficiency electronic circuit soldering paste. Background technique [0002] Reasonable arrangement of components, reliable connection and reasonable wiring of the circuit are the prerequisites for the normal operation of the circuit. The connection of components in the circuit usually has several methods such as welding, plugging and winding. The advantages of welding are reliable contact, firm fixation, and long-term use of the circuit. Therefore, electronic products generally adopt the method of welding. The purpose of soldering is not only to ensure the reliable electrical connection in the circuit, but also to make the components firmly fixed on the circuit board. Therefore, the welding work should not be sloppy, otherwise it is easy to cause poor contact due to false welding, or the welding surface is easy to break. Careless soldering will also cause the copper foil of the circuit electrode to fall off or even ...
