Abstract

The invention provides a water-based printed circuit board (PCB) cleaning agent. The cleaning agent is prepared from the following raw materials in parts by weight: 2-3 parts of sodium borate, 1-2 parts of potassium pyrophosphate, 3-4 parts of coconut oil alkylolamide phosphate, 4-5 parts of fatty alcohol-polyoxyethylene ether, 2-3 parts of citric acid, 30-40 parts of ethanol, 4-5 parts of auxiliary and 100-120 parts of deionized water. The cleaning agent has the beneficial effects that the cleaning agent has the capability of quickly removing rosin, soldering tin, metal ions, fingerprints and the like, can not cause short circuits easily, is less in loss, ensures better printing quality, reduces the cost and saves time, thus greatly reducing the rejection rate and manufacturing more PCBs with better quality more quickly; the auxiliary can form a protective film on the surface of the circuit board to isolate air to prevent water and other molecules in the air from corroding the circuit board; the cleaning agent is resistant to oxidation and is convenient for operation of the next preparation process.

Description

technical field [0001] The invention relates to the field of cleaning agents, in particular to a water-based PCB circuit board cleaning agent and a preparation method thereof. Background technique [0002] With the rapid development of integrated circuits, the volume of circuit boards is getting smaller and smaller, and electronic components are getting smaller and denser. If the dirt and dust inside are not cleaned during the production process, it may cause problems such as short circuit and corrosion, which will affect the normal operation of the circuit board. At present, most circuit board cleaners are made of organic substances, which have good cleaning effect and are not easy to cause problems such as short circuit and corrosion. However, organic compounds are not only expensive, but also pollute the environment, destroy the ozone layer, and are harmful to human health. There are also a few water-based cleaning agents, but the cleaning effect is limited and there are...
