Electronic Packaging and New Energy Materials
Application Background
Organic solvents play a important role in modern industry, and can be used in chemical industry, medicine, tanning industry, metallurgy and electronics and many other fields. Some applications present higher requirements for the purity of organic solvents, so that dehydration and purification of organic solvents are required.
With the miniaturization of electronic components and the explosive growth of the new-energy vehicle industry, moisture control in electronic packaging materials and battery structural adhesives has reached unprecedented levels of demand.
In electronic packaging, trace moisture causes:
- ♦ Bubble formation in the encapsulating resin, impairing chip heat dissipation and insulation
- ♦ Moisture attacks the metal lead frame, causing electrochemical corrosion
- ♦ Vapor expansion during high-temperature curing leads to package cracking
In new-energy batteries, moisture in the structural adhesive (used to bond cells to the housing) causes:
- ♦ Side reactions with the battery electrolyte, shortening cycle life
- ♦ Loss of bond strength in the structural adhesive, creating safety risks
- ♦ Gas release at high temperature, raising internal cell pressure
