Material Notes:
COB/DCA Encapsulants are essential to the reliability of flip chip assemblies because they minimize the thermal mismatch between the flip chip and substrate.Loctite® Underfills and Encapsulants improve assembly operations by providing superior reliability and faster throughput. Improved reliability is achieved through products that have a high Tg, low CTE, high throughput and excellent adhesion. Faster throughput and higher yields are achieved through faster flow characteristics and increased cure speeds.Loctite® 3534 Glob Top EncapsulantA glob top encapsulant for transistors, smart cards, diodes and ICs in Chip-On-Board (COB) applications where potting wells/indentations are not provided.
