Pros & Cons

Pros

✓ Pure silver + ceramic filler, over 88% thermally conductive by weight
✓ Three particle shapes maximize contact area and heat transfer
✓ Not electrically conductive, so no shorted pins if it spreads
✓ Controlled triple-phase viscosity for stable long-term performance

Cons

✗ Requires 200-hour cure time to reach peak conductivity
✗ Capacitance can cause issues if it bridges nearby surface traces
✗ Thick viscosity needs careful thin-line spreading on the IHS
✗ Overkill for casual users versus cheaper everyday pastes
