Introduction

With the rapid development of electronic technology, packaging materials of electronic components play a crucial role in ensuring their performance and reliability. Encapsulation materials not only need to have good mechanical strength, heat resistance and electrical insulation, but also need to remain stable during long-term use to extend the service life of electronic components. In recent years, the research and development and application of a new generation of sponge hardener has injected new vitality into electronic component packaging materials and has become a secret weapon to extend its service life.

1. Current status and challenges of electronic component packaging materials

1.1 Basic requirements for packaging materials

The main function of electronic components packaging materials is to protect the internal circuit from the influence of the external environment, such as humidity, temperature, mechanical impact, etc. Therefore, packaging materials need to meet the following basic requirements:

Mechanical strength: Can withstand certain mechanical stresses and impacts.
Heat resistance: Stay stable in high temperature environment without deformation or degradation.
Electrical Insulation: Prevent current leakage and ensure the normal operation of the circuit.
