Abstract

The invention relates to the technical field of swelling agent preparation, and specifically discloses a circuit board swelling agent and a preparation method thereof. The raw material composition comprises the following parts by weight: 40-60 parts of ε-caprolactone; 10-20 parts of N-methyl-2-pyrrolidone; 5-10 parts of biological oil. The circuit board swelling agent of the present invention has simple components, and has a high ability to remove residues in hole walls during the processing of printed circuit boards using epoxy resin materials as substrates.

Description

technical field [0001] The invention relates to the technical field of swelling agent preparation, in particular to a circuit board swelling agent and a preparation method thereof. Background technique [0002] PCB (Printed Circuit Board), the Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. Most of the existing circuit boards use epoxy resin materials as the substrate, and there will be residues in the hole wall during the processing process, and removing the residues is a necessary process in the circuit board processing process. The general method is to put it in a swelling agent for treatment, but the existing swelling agent has a general ability to remove residues. Therefore, the development of a swelling agent with strong ability to remove circuit board residues has an important market prospect. Cont...
