Abstract

The invention discloses a preparation method of an acidic degreaser for a PCB, and relates to the technical field of degreasers. The acidic degreaser is prepared from the following raw materials in parts by weight: 80-100 parts of deionized water, 22-34 parts of cycloalkane, 18-30 parts of ethanol, 10-20 parts of organic amine ester, 5-10 parts of an emulsifier, 10-20 parts of a metal cleaning agent and 4-8 parts of a surfactant. The cycloalkane is added into the degreaser, oil stains on the surface of a PCB are dissolved through cycloalkane, so that the degreasing effect of the PCB is improved. The organic amine ester is added into the degreaser, metal oxides on the surface of the PCB can be dissolved, and the degreasing effect of the PCB is further improved. Meanwhile, the ethanol solution is added into the degreaser disclosed by the invention, so that the surface of the PCB can be disinfected, and the air drying time of water on the surface of the PCB can be shortened due to the fact that ethanol is easy to volatilize, so that the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of degreasing agents, in particular to a preparation method of an acidic degreasing agent used for PCB circuit boards. Background technique [0002] PCB (printed circuit board) is a printed circuit board, referred to as a printed board, and is one of the important components of the electronics industry. Almost every kind of electronic equipment, ranging from electronic watches and calculators to computers, communication electronic equipment, and military weapon systems, as long as there are electronic components such as integrated circuits, in order to make the electrical interconnection between various components, printed circuit boards must be used. plate. The printed circuit board is composed of an insulating base plate, connecting wires and pads for assembling and welding electronic components, and has the dual functions of a conductive line and an insulating base plate. It can replace complex wiring a...
