PLENSETTM Electrically conductive type
What is the PLENSETTM Electrically conductive type?
As an electrically conductive adhesive, the electrically conductive type combines low-temperature curing at 80degC with conductivity and adhesion.
It can also inhibit galvanic corrosion, which is an issue with general electrically conductive adhesives.
Have you experienced these issues?
Here is the product that resolves these issues. PLENSETTM Electrically conductive type
Alternative for solder
Die attach agent (heat-dissipating)
Galvanic corrosion inhibition/electrically conductive adhesives
Issues with general conductive paste
When nickel and tin are used as terminals, the difference in electric potential in high temperature and high humidity environments causes the formation of a battery, which results in galvanic corrosion and increased contact resistance.
When dissimilar metals with different electric potentials are joined, corrosion phenomena occur in high-temperature, high-humidity environments between metals with large potential differences. This phenomenon is known as galvanic corrosion.
Example: Electrically conductive adhesive (Ag) and metal terminal (Sn, Ni, etc.)
As a result, a battery is formed as shown in the figure, and the contact resistance between the electrically conductive adhesive and the metal terminal increases.
If galvanic corrosion can be inhibited...
Electrically conductive adhesives can be substituted for solder. It also eliminates the need for reflow (high-temperature processing) and flux cleaning, thereby reducing the number of processes and allowing the use of materials with low heat resistance.
