Abstract

The invention provides a cleaning agent for chip capacitors. The cleaning agent consists of the following components in percentage by weight: 40-60% of ethanol, 20-30% of diethyl glutarate, 10-20% of diethylene glycol monobutyl ether, 5-15% of isobutyl acetate, 3-8% of surfactant and 2-5% of dispersing agent. The cleaning agent solves the problems that an existing clip capacitor cleaning agent is high in volatility and is not environment-friendly.

Description

technical field [0001] The invention relates to the technical field of chip capacitors, in particular to a cleaning agent for chip capacitors. Background technique [0002] Chip capacitors are important electronic components in the surface mount technology of electronic products. They are printed on ceramic substrates with a resistive paste with a certain resistivity and then sintered. [0003] Chip capacitors use ceramic materials containing adhesives in the manufacturing process, which are composed of polymer resin, curing agent, plasticizer, dispersant, defoamer and ceramic materials. The sintering temperature in the production is above 1000°C. A solid ceramic diaphragm is formed, and some residues will be produced at the same time. The residues must be thoroughly cleaned to ensure the temperature stability, capacity stability and dielectric loss stability of the chip capacitor. The main components of cleaning agents that have been used for many years are trichlorethylen...
