LoSTRESS™ Liquid Encapsulants

LoSTRESS™ Liquid Encapsulants

<i>Lo</i><b>STRESS</b>™ Liquid EncapsulantsLoSTRESS™ Liquid Encapsulant is a new generation low modulus fill material specifically designed to offer low cure stress and low warpage.

These encapsulants are novel, epoxy-based 100% solids, single component liquid semiconductor encapsulants designed for devices requiring high toughness, flame retardancy and strong adhesion to various substrates such as metal, ceramic and organic. LoSTRESS™ is especially suitable for SAW filter applications. LoSTRESS™ can virtually eliminate warp on ceramic substrates due to the low cure stress. Dam and fill and glob top versions are available.

 

Key Benefits:
• Very little warpage on HTC and LTCC substrates for easy downstream process.
• Minimal cure stress on sensitive devices such as SAW filters.
• High adhesion to die, substrates and most other interfacing materials.
