ECM Intros New Dam and Fill Chip Encapsulants for COB
Delaware, OH — Engineered Con - duc tive Materials, LLC, a subsidiary of Engineered Material Systems, is
Encapsulants for chip-on-board (COB) applications. Because of the new material’s
low expansion coefficient, these filled encapsulants protect wire bonds and reduce stresses associated with ther- mal cycling. In addition, the materi- als are engineered to withstand cir- cuit board reliability test criteria. DE-7826 and CE-7826 have
thermal expansion coefficients in the 20 ppm range when measured by
Dam and fill encapsulating material.

Fancort: Adjustable Two-Sided Tooling for Flatpacks
West Caldwell, NJ — The SMT Tool Division of Fancort has introduced another of the company’s “universal” form and trim systems to add to the family of “universal” systems includ- ing the FLEX and one-sided F-1B/3A. The new system processes two
sides at one time on flatpacks only, not quadpacks. The new tool has a customer-specified fixed foot, typical- ly 1 to 1.25mm (0.040 to 0.050-in.); adjustable standoff height using dig- ital inch/metric vernier; adjustable
Thermal Mechanical Analysis (TMA). Both products have high glass transition temperatures (Tg) and modulus to retain their low expansion properties throughout the operating temperature range of the circuit board. The encapsulants meet circuit
assembly and semiconductor stan- dards for ionic cleanliness (extractable ions) to prevent corro- sion in high temperature and humid-
ity environments. DE-7826 and CE- 7826 are the latest additions to the company’s extensive line of electron- ic materials for semiconductor, cir- cuit assembly, photovoltaic, printer head, camera module, disk drive and
photonic applications. Contact: Engineered Conductive Materials, LLC, 132 Johnson Dr.,
