DM4030LD is a silver-loaded thermoplastic paste designed to attach large
semiconductor devices, heat sinks, and/or substrates. DM4030LD provides a low
stress, resilient bond for large-area, highly-mismatched materials. Due to a
patented polymer/solvent system, DM4030LD can be processed at temperatures
as low as 150–175°C yet still give void-free, thin bondlines to maximize thermal
transfer. DM4030LD is easily reworked and will not harden or become brittle with
time because of its unique thermoplastic nature. High silver loading and excellent
particle-to-particle contact result in a high thermal conductivity of 15 W/m°K.
DM4030LD/H887 is a new version with stable adhesion after pressure-cooker
testing.
