SMA
Surface Mount Adhesive
SMA is a heat curable, one-part thixotropic adhesive. It has high uncured green strength and a fast cure cycle
with medium bond strength. It is used for holding components in place during soldering operations in surface
mount assemblies.
• High 'green strength'; ensures components do not move during handling and before curing
• Single-part system with thixotropic properties; high dot profile
• Long term stability after cure cycle; flexible in cured state to ensure components are not stressed
• Fast cure heat cure or at 90°C for component safety; not affected by UV light during assembly
