Insul-Bond Epoxy Adhesives Two-Part, Low Temperature Cure, High Peel Strength Systems
Insul-Bond 16 & 17 adhesives are solvent free, electrically non-conductive epoxy systems designed for die attachment, substrate mounting and lid sealing in hybrid microelectronics applications. These 2-part systems feature rapid cure at very low temperatures and outstanding bond "peel" strengths-typically 10 times greater than standard epoxy materials. Application by screen printing (180-225 SS mesh) or automatic dispensing is recommended.
