Embodiment 1

[0029] Raw material and weight percent are as follows: Isomerized fatty alcohol polyoxyethylene ether C 10 h 21 O(C 2 h 4 O) 7 H 15%, monoethanolamine 10%, N-methylpyrrolidone 20%, ethylene glycol monobutyl ether 15%, ethylenediaminetetraacetic acid 2%, benzoic acid 0.05%, pure water balance.

[0030] The cleaning method adopts the above method. Compared with the existing cleaning solution, after cleaning the surface pollutants on the LED chip, there is no residue on the chip surface, the cleaning efficiency is high, and the corrosion rate to the substrate material and metal wiring is very small.

Embodiment 2

[0032] Raw material and weight percent are as follows: Isomerized fatty alcohol polyoxyethylene ether C 10 h 21 O(C 2 h 4 O) 17 H 5%, diethanolamine 10%, N-methylpyrrolidone 5%, ethylene glycol monoethyl ether 10%, ethylenediaminetetraacetic acid sodium salt 1%, 2-ethylbenzoic acid 1%, pure water balance.

[0033] The cleaning method and cleaning effect are the same as in Example 1.

Embodiment 3

[0035] Raw material and weight percent are as follows: Isomerized fatty alcohol polyoxyethylene ether C 10 h 21 O(C 2 h 4 O) 7 H 1%, triethylamine 10%, N,N-dimethylformamide 20%, diethylene glycol monobutyl ether 10%, nitrilotriacetic acid sodium salt 1%, 3-ethylbenzoic acid 0.05% , Pure water balance.

[0036] The cleaning method and cleaning effect are the same as in Example 1.

Abstract

The invention discloses a cleaning solution for a light-emitting diode (LED) chip. A preparation method for the cleaning solution is simple, and the cleaning solution is low in cost and high in cleaning efficiency, and has low corrosion rate to substrate materials and wire harnesses. The cleaning solution consists of the following components in percentage by weight: 1 to 15 percent of isomerized fatty alcohol-polyoxyethylene ether, 1 to 20 percent of organic amine, 1 to 20 percent of organic amide solvent, 1 to 15 percent of alcohol ether solvent, 0.1 to 5 percent of nitronic acid-containing chelating agents, 0.01 to 5 percent of arylcarboxylic acid, and the balance of pure water.

Description

technical field [0001] The invention relates to a cleaning agent for LED chips, in particular to a cleaning solution for LED chips with simple preparation method, low cost, high cleaning efficiency and low corrosion rate to substrate materials and wiring. Background technique [0002] Because light-emitting diodes (LEDs) have many advantages such as high efficiency, energy saving, and environmental protection, their prospects in the lighting market have attracted the attention of countries all over the world. In the manufacturing process of LED chips, in addition to chip manufacturing technology, chip packaging technology and heat dissipation technology, the cleaning technology of LED chips also has a significant impact on its luminous efficiency, brightness and service life. During the LED chip manufacturing process, the main purpose of cleaning the wax, film-forming agent, inorganic impurities, metal particles and other pollutants on the chip surface is the main purpose of...
