Abstract:
The invention provides fluoropolymer compositions containing silylether-blocked compounds, fluorine-containing polymer, and an organo-onium compound. The invention also provides silylether-blocked compounds, articles made from said fluoropolymer compositions, and methods of making said articles.
Abstract:
Mold compounds for encapsulating semiconductors are disclosed. The compounds achieve high levels of adhesion to uncleaned printed wiring board substrates by minimizing the level of silicone fluid in the compound. Methods for encapsulating semiconductor dies and processes for encapsulating the dies also are disclosed.
