Abstract

The invention discloses an LED chip cleaning solution. The LED chip cleaning solution comprises the following raw materials by mass: 10 to 15 parts of alkylolamide polyoxyethylene ether, 10 to 15 parts of sorbitan fatty acid ester polyoxyethylene ether, 5 to 8 parts of benzotriazol, 3 to 4 parts of citric acid, 1 to 2 parts of glycerin, 1 to 2 parts of ethanol, 5 to 8 parts of polyoxyethylene ether, 5 to 8 parts of hydrogen peroxide, 2 to 4 parts of ammonium hydroxide, 6 to 10 parts of 1,3-dioxolane, 6 to 8 parts of t-butyl-4-methoxyphenol and 4 to 5 parts of tripropylene glycol methyl ether. The LED chip cleaning solution is high in cleaning efficiency, strong in detergency, good in safety performance, free of pollution to environment, reduced in consumption of energy and low in washing cost; and in the process of washing, the cleaning solution causing no damage to LEDs can form a protection film on the chip, isolate air, prevent water and other molecules in the atmosphere from corroding the chip, resist oxidation and facilitates subsequent operations.

Description

technical field [0001] The invention relates to the field of cleaning agents for LED lamps, in particular to a cleaning solution for LED chips. Background technique [0002] LED is a semiconductor light-emitting diode. LED energy-saving lamps use high-brightness white light-emitting diodes as light sources. They have high luminous efficiency, low power consumption, long life, easy control, maintenance-free, safety and environmental protection; Bright, colorful, low loss, low energy consumption, green and environmental protection. Existing LED lampshade materials have poor flame retardancy. [0003] In the manufacturing of electronics industry, the production and assembly of electronic components consists of multiple stages, and each stage has a cleaning process to ensure high reliability and high yield of products. Problems with electronic components due to contamination by particles and improper cleaning include high leakage, short circuit, corrosion, detection failure, p...
