Engineered Material Systems introduces new dam and fill chip encapsulants for smart card assembly applications

Engineered Material Systems, a leading global supplier of electronic materials for circuit assembly applications, is pleased to debut its 640-35 (dam) and 640-46 (fill) dam and fill UV cured chip encapsulants for chip-on-board smart card applications.


These new encapsulants are designed to protect wire bonds and reduce the stresses associated with thermal cycling. These materials are engineered to withstand circuit board reliability test criteria.

The dam and fill UV cured chip encapsulants cure rapidly when exposed to intense UV light centered at 365nm. They have been developed for encapsulating small chips in smart card applications where fast processing is required. 640-35 and 640-46 are the latest additions to Engineered Material Systems’ extensive line of electronic materials for semiconductor, circuit assembly, photovoltaic, printer head, camera module, disk drive and photonic applications.
