The Electronics Group of Henkel has developed two new, high-purity dam and fill encapsulants designed specifically for lead-free processing. Hysol FP4451TD and Hysol FP4800 both meet the stringent JEDEC level testing requirements for high-temperature reliability demanded by lead-free processes.
The two products enable smaller, thinner and lighter wirebonded cavity down, SuperBGA and Viper BGA packages, while supporting high-throughput, low-cost package assembly processes.
Dam heights greater than 1mm 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.

In addition, its ionic contamination level is lower than earlier-generation products.
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 up to 260C 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: BGAs, PBGAs, CSPs, full arrays on LTCC, transistors, system in package (SIP), microprocessors and ASICs.
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, backed by in-depth technical and engineering support, 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. Request a free brochure from Henkel Loctite Adhesives....
