Elecolit® conductive adhesives are both electrically and thermally conductive adhesives. They contain metallic filling materials, primarily silver flakes which creates efficient energy flow and high conductivity.
The percentage of conductive filler greatly influences the degree of conductivity within the adhesive. With a higher fill ratio, conductivity increases due to the fact that more conductive particles come in contact with each other to create a conducting path. Conductivity can further be improved through the size and geometry of the conductive particles that are used to fill the adhesive.
The adhesive curing process also plays a significant role in maximising conductivity. Shortened curing cycle times and excessively low curing temperatures can lead to low crosslinking density. Too short curing times or too low curing temperatures lead to the occurrence of low crosslinking density and the build-up of excessive bonding stresses within the adhesive. Until recently, the curing of conductive adhesives was a slow process.
However new developments in catalyst technology means conductive adhesives can be now cured within a few minutes. Several one-part Elecolit® conductive adhesives have been modified for the ability to snap cure. Elecolit® conductive adhesives are relatively simple to apply. With the appropriate selection of filler type, they can be dispensed through automated valves, high speed “Jet” dispensing systems, and screen printing.
There are many benefits to using conductive adhesives:
- Lead and solvent-fee
- Micro-dispensing by screen printing or jetting
- Vibration resistant connections
- High temperature resistance
- No bleeding
- Snap cure and lower temperature curing options available
- RoHs compliant
