Dam heights greater than 1 mm are possible with Hysol FP4451TD, a tall dam flow control barrier recommended for package level applications. It offers superior dispensing and a high aspect of ratio of 0.70 height to width. Based on proven resin chemistry, FP4451TD exhibits excellent chemical resistance and thermal stability.
Hysol FP4800 is a liquid encapsulant with excellent adhesion that can withstand solder temperatures of up to 260 ºC after JEDEC level 2 preconditioning. Its excellent flow properties allow it to penetrate fine-pitch wires and deep cavities without entrapping voids. Like all Hysol high-purity encapsulants, FP4800 is self-leveling and offers unprecedented performance for numerous advanced packages.
With the addition of FP4451TD and FP4800 to the Hysol lead-free materials set, manufacturers can be confident of having a full range of products to meet the EU lead-free implementation date of July 2006. All Henkel lead-free products are designed to support high-quality advanced assembly processes at full production levels.
