Galvanic corrosion inhibition/electrically conductive adhesives
Issues with general conductive paste
Generally, conventional conductive adhesives are composed of a dispersion of silver (Ag)
powder.
However, this composition can lead to the issue of galvanic corrosion in high temperature and high
humidity environments. Specifically, when using nickel (Ni) or tin (Sn) as terminal materials, a galvanic cell can
form due to the potential difference in such environments, leading to galvanic corrosion. This corrosion causes an
increase in contact resistance, resulting in malfunctions.
This increase in
contact resistance due to corrosion negatively affects the reliability and performance of electronic devices. In
the case of conductive adhesives (Ag) and terminal metals (such as Sn and Ni), the situation is as follows.




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...
PLENSETTM Conductive Type has the characteristic of suppressing galvanic corrosion,
which commonly occurs with conventional conductive adhesives.
This innovative feature addresses many issues and
expands the range of applications for conductive adhesives.
By using PLENSETTM Conductive Type, it
can
particularly serve as an alternative to solder. The need for reflow (high-temperature processing) and flux cleaning required with solder is
eliminated. Furthermore, the low-temperature curability PLENSETTM Conductive Type allows the use of materials with low heat resistance.
This enables the use of heat-sensitive
electronic components and materials, significantly increasing design flexibility.
These benefits greatly enhance manufacturing process efficiency and are expected to reduce
production costs.






PLENSETTM Conductive Type effectively suppresses galvanic corrosion, overcoming the challenges associated with conventional conductive adhesives, and provides an excellent solution that meets diverse manufacturing needs. This innovative product enables process efficiency, cost reduction, and greater design flexibility, making it a powerful tool for maintaining a competitive edge in the electronics industry.
