Abstract

The invention discloses a sandwich panel swelling agent and a preparation method thereof. The sandwich panel swelling agent comprises the following components in volume fraction: 10%-12% of pure water, 80%-83% of dimethylformamide, 3%-5% of sodium hydroxide and 3%-5% of an additive. The preparation method comprises the following steps: controlling the temperature at 30-40 DEG C, adding a part of pure water into a stirring tank, adding dimethylformamide in proportion, and stirring; then adding analytically pure sodium hydroxide, and stirring; adding the additive, and stirring; adding pure water until the liquid level reaches a liquid level scale mark; sampling to analyze the content of each component in the prepared mixed liquid, correcting to a specified value by virtue of pure water, and reserving and sealing the sample. The sandwich panel swelling agent has very good swelling and processing effects to a PCB, is toxic free and harmless and does not pollute the environment; furthermore, in whole preparation process, the operation is simple and controllable, and the practicability is good; the sandwich panel swelling agent is suitable for large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of industrial cleaning agents, and in particular relates to a leavening agent for multi-layer boards and a preparation method thereof. Background technique [0002] PCB (Printed Circuit Board), the Chinese name is printed circuit board, referred to as printed board, 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, printed boards are used for the electrical interconnection between them. . [0003] In the production and processing of PCB boards with through holes, a key link is the hole metallization process. This process converts non-conductive insulating through-holes into active conductive through-holes, and the existing PCB boards make holes for conduct...
