Abstract:
The hermetic seal of the backside of a substrate of an integrated circuit module is provided by a composition containing about 51.4 to about 60.6% by weight of an epoxy polymer; about 39 to about 48% by weight of a hardener and flexibilizing portion; and up to about 0.6% by weight of a coloring agent.
Abstract:
A protective layer composition, suitable for protecting metal electrodes on components and other microelectronic circuitry, comprises an organic thermoplastic polymeric material, an organic solvent or solvents, and a non-ionic fluorocarbon surfactant as a wetting/leveling/flow control agent. A typical formulation comprises an aromatic polymer which cures to form a polyamide-imide polymer, an organic solvent or a mixture of orangic solvents and a non-ionic fluorocarbon surfactant.
Abstract:
A film-forming composition comprising an organic flux base material; and a carboxylic acid anhydride and/or aldehyde; and a process for using are provided.
Abstract:
Cured epoxy compositions are removed from substrates by employing compositions containing an organic cyclic alcohol and a surface-active agent.
