Chip Encapsulants reach full cure in shadowed areas.

Press Release Summary:




Designed with UV/Vis light and secondary ambient moisture-cure system, Dual-Cure 9101, 9102, and 9103 are suited for encapsulation applications where shadowed areas are present. Materials are tack free after UV cure, and 2-day moisture cure further shortens time for handling as well as final testing and assembly. With varying viscosities of 7,000, 17,000, and 25,000 cP, products are jet dispensable. Cured materials are flexible and expand with heat, reducing stress on board components.

Light-Curable Encapsulants Reach Full Cure in Shadowed Areas



Dymax Dual-Cure 9101, 9102, and 9103 are resilient, chip-encapsulant materials designed with a UV/Visible light and secondary ambient moisture-cure system, making them ideal for encapsulation applications where shadowed areas are present.  These materials cure tack free after UV cure, so boards can be handled sooner with less potential for damage.  The two-day moisture cure – versus the seven days typical with other systems – shortens the time for further handling as well as final testing and assembly.



These three new materials have varying viscosities of 7,000, 17,000, and 25,000 cP, allowing for performance and dispensing to be optimized, and are jet dispensable for more accurate placement and more efficient material usage.  The cured materials are flexible and expand with heat, reducing stress on board components.  No refrigeration is required for transporting the uncured material, so no additional associated costs are incurred.



The 9100 series of new Light/Moisture-cure encapsulants is a significant addition to the Dymax portfolio of printed circuit board assembly materials, which include conformal coatings and encapsulants, as well as edgebonding and masking materials, and other related products.
