Abstract

The present invention is an epoxy adhesive used in the integrated molding technology of electronic components and a preparation method thereof. The epoxy adhesive is composed of the following components in parts by weight: 30-70 parts of epoxy resin; 1-70 parts of curing agent 10 parts; accelerator 1-10 parts; solvent 20-40 parts; auxiliary agent 0.1-5.0 parts. Compared with the previous technology, the present invention can meet the requirements of the integral molding process, and better adapt to the different requirements of the new process than traditional adhesives; the adhesive has high body strength, high modulus, high Tg, and high adhesion Strength, with higher reliability. The epoxy adhesive can meet the production process requirements of the integral molding process of electronic components, and has higher reliability.

Description

technical field [0001] The invention relates to an epoxy adhesive and a preparation method thereof. The epoxy adhesive is mainly used in an integral molding process of components represented by integrally formed inductors to improve the production efficiency and stability of the components. Background technique [0002] The emergence of integrally formed electronic components represented by integrally formed inductors is attributed to the development of computer motherboard technology and the development of power supply technology. The main frequency of the CPU is getting higher and higher, so there are high requirements for stable power supply and filtering. The integrated inductor can work for a long time under the condition of high current, and can provide stable power supply for the CPU. As electronic products become smaller and more powerful, electronic components are also developing towards smaller size and higher power. Good material properties and special design mak...
