Abstract
The invention belongs to the technical field of surfactants, and particularly relates to a chemical preparation for the field of LEDs and a composition for cleaning solid wax of an LED chip. Comprises 15-20% of abietyl imidazoline nonionic surfactant, 2.5-3% of penetrating agent, 8-10% of emulsifying agent, 1.5-2% of chelating agent, 8-10% of organic auxiliary agent and the balance of high-purity water. According to the invention, the rosin-based imidazoline nonionic surfactant, the penetrating agent and the emulsifying agent are mixed, so that the solid wax can be rapidly emulsified and dissolved, the metal electrode material is protected, the problem of corrosion of a water-based product on the market to the metal electrode is solved, and the water-based product is easy to clean and has no residue.
Description
Technical Field
The invention belongs to the technical field of surfactants, and particularly relates to a chemical preparation composition for the field of LEDs, which is used for cleaning solid wax of an LED chip.
Background
Before the LED chip packaging test, one surface of the functional area needs to be coated with solid wax, the functional area is fixed on a grinding disc under the pressure, and the exposed surface of the chip is subjected to grinding and polishing operation. After grinding and polishing, the chip is cleaned by a solid wax cleaning agent to recover the functional surface of the chip. The main components of solid waxes currently used in the industry are long chain fatty acids, rosin and denatured rosin derivatives.
