LORD CoolTherm™ ME-543 encapsulant is an anhydride-free, thermally conductive, semiconductor grade epoxy underfill product developed for the encapsulation of densely populated area array flip chip devices. It is formulated with the necessary structural strength to handle over-molding processes. Features: provides thermal conductivity for applications where superior heat dissipation is required. provides low viscosity for high speed jetting dispense. provides surface tension and viscosity flow properties to achieve full coverage without producing bulky fillet on top of device. formulated to flow consistently without voids while maintaining a fast flow rate; can be used under small or large dies with high-density interconnects and under devices with stand-off heights below 25 micron. minimizes the possibility of cracking during temperature cycling (-40°C to +150°C); provides excellent thermal shock performance. provides good adhesion to laminate, ceramic, solder mask and metal surfaces. provides high Tg and high fracture toughness, reducing the amount of thermally induced stress placed on the solder interconnects.
