About Light Cure Encapsulants for Electronic and PCB Assembly

Dymax 9000 Series Encapsulants are tough, flexible UV curing electronics-grade encapsulants which are single part and cure in seconds; they cut costs and processing times associated with electronic assembly. These encapsulating materials have high ionic purity, excellent adhesion and resistance to humidity and thermal stock to effectively protect components. They contain no sharp, abrasive mineral or glass fillers to abrade fine wires, and their combination of low Tg and low modulus means low stress. Ultraviolet light-curing resins are ideal for glob top and chip on board (COB) applications and are especially suited for encapsulating IC´s on flex circuits. Clear and black grades are available along with a wide range of viscosities, from thin wicking to non-flowing gels for dam and fill.

Encapsulants – Dual Cure Systems

Dymax 9100 Series are designed with a UV/visible light and secondary ambient moisture-cure system, making them ideal for applications where shadowed areas are present. The materials produce a tough, flexible encapsulant for bare die, wire bonds or integrated circuits. They cure tack free after UV cure, so pcb assemblies can be handled sooner with less potential damage. Moisture cure is obtained after two days compared to the typical seven days with other systems, shortening the time for further handling as well as final testing and assembly. These materials are available in varying viscosities, allowing for performance and dispensing to be optimised. They are jet dispensable for more accurate placement and more efficient material usage. The cured encapsulants have high CTE and low Tg, giving flexibility and low stress.

Dymax LED protection encapsulants are also available to enhance LED performance.
