LOCTITE® ABLESTIK 2053S

Known as ABLEBOND 2053S (10G)

Features and Benefits

This red, non-conductive die-attach adhesive is designed for flex, laminate and die-to-die.
LOCTITE® ABLESTIK 2053S is a polymer-filled, hybrid, non-conductive die-attach adhesive for array packaging. It's typically used for the ASIC (Application Specific Integrated Circuit) attach of automotive optical sensors, and as a receiver and die-attach for 3D sensing modules. It's proven effective on various substrates, such as EMC, engineering plastic, glass and metals, and offers low warpage, stress and moisture uptake. It s a low-modulus adhesive, making it ideal for wire bonding small die sizes and chip bonding on FR4 substrates. It cures when exposed to heat.
