Abstract

The invention provides a preparation method of an electronic circuit board cleaning agent. The preparation method comprises the following steps: firstly, mixing ethylene glycol monomethyl ether, 1-hydroxy-ethanesulfonic acid and a polyol solvent to obtain a premixed solution; dissolving polyethylene glycol oleate, sodium diethylhexyl sulfosuccinate, secondary alkyl sodium sulfonate, alkyl polyglucoside and potassium pyrophosphate into deionized water, adding the premixed solution, N-methyl-2-pyrrolidone, modified silica gel and 2, 2 '-azodiisobutylamidine dihydrochloride, and carrying out reflux reaction in a nitrogen atmosphere so as to obtain the product. The cleaning agent is suitable for cleaning electronic circuit boards and has a good cleaning effect and does not cause corrosion andrusting of the electronic circuit boards.

Description

technical field [0001] The invention relates to the technical field of cleaning electronic circuit boards, in particular to a preparation method of a cleaning agent for electronic circuit boards. Background technique [0002] The electronic circuit board is one of the important parts 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 each component The electrical interconnection between must use the electronic circuit board. [0003] In the manufacturing process of electronic circuit boards, its cleaning is often neglected. However, with the long-term use of the products on the client side, problems caused by ineffective cleaning in the early stage lead to many failures, and the repair or recall of products causes a sharp increase in operatin...
