Embodiment Construction

[0005] Preferred embodiments of the present invention will be demonstrated below. To avoid obscuring the content of the present invention, the following description omits known components, related materials, and related processing techniques.

[0006] The cleaning agent of the present invention contains at least three components: hydrofluoroether, fluoroalcohol, and an organic solvent different from the hydrofluoroether and fluoroalcohol. Hydrofluoroethers (HFE) refer to hydrofluorocarbons containing ether bonds in their molecular structure. The hydrofluoroethers suitable for the present invention generally have a total carbon number of about 4-10, and preferably have no unsaturated carbon-carbon bonds. The molecular structure of hydrofluoroether can be straight chain, branched chain, cyclic or their combination (such as alkyl alicyclic structure). The hydrofluoroether preferably has a boiling point of 50-275°C, preferably 50-200°C, more preferably 50-110°C. Hydrofluoroethe...

Abstract

The invention provides a cleaning agent used on electronic elements. The cleaning agent comprises hydrofluoroether, fluoroalcohol and an organic solvent different from hydrofluoroether and fluoroalcohol. With the total weight of the cleaning agent as a reference, the content of fluoroalcohol is higher than 0wt% and lower than 1wt%. The invention also provides a method for applying the cleaning agent.

Description

technical field [0001] The present invention relates to a cleaning agent, in particular to a cleaning agent for electronic components. Background technique [0002] With the rapid development of integrated circuits, electronic components are getting smaller and denser. During the production process, if the dirt and dust inside are not removed cleanly, it may cause problems such as short circuit and corrosion, which will affect the normal operation of the circuit board. At present, most electronic component cleaners are made of organic substances, which have good cleaning effect and are not easy to cause problems such as short circuit and corrosion. [0003] The known technology uses chlorofluorocarbons as cleaning agents, and its main advantage is that it is non-flammable or non-flammable, and the most widely used one is 1,1,2-trifluorotrichloroethane (CFC-113 for short). However, CFCs were banned in 1996 due to environmental concerns. Cleaning agents that replace chlorof...
