摘要： A photosensitive resin composition comprising a pre-imidized aromatic polyimide, which when coated on a silicon wafer, has a light transmittance at a wavelength of 365 nm of at least 1% and imparts low residual stress after cure. The composition can be patterned through I-line exposure followed by development with organic or alkaline solutions, and can be cured at relatively mild temperature to yield low-stress polyimide patterns. Electronic components having the polyimide patterns have high reliability.

摘要： The low modulus polyimide adhesive compositions of the present invention contain a low modulus polyimidosiloxane polymer, a thermosetting substantially-non-halogenated epoxy (optionally including an epoxy catalyst), a plasticizer, an insoluble halogen-free flame-retardant filler, and optionally an adhesion promoter.

The adhesive is generally resistant to unwanted curl even in cases where the adhesive polyimide and the base film polyimide have a coefficient of linear thermal expansions (measured between 50° C. and 250° C.) that differ by more than 10, 15, 20 25, or 30 ppm/° C.

摘要： The present invention is directed to coverlay compositions derived from two-layer polyamic acid-based composites having a cover layer and adjacent thereto an adhesive layer wherein the cover layer comprises polyamic acid and other additives allowing the composition to be photosensitive and aqueous base developable, and where the adhesive layer can form a polyimide having a glass transition temperature between 170 and 250° C. The two-layer coverlay compositions of the present invention are used to encapsulate metal circuit traces formed on a flexible printed circuit base substrate. These two-layer compositions are particularity useful due to having an overall in-plane CTE between 10 and 40 ppm/° C. a range that is useful in avoiding unwanted curling of a flexible printed circuit when used as a polyimide-based coverlay material.

摘要： Water absorption resistant polyimide/epoxy-based compositions, like pastes (or solutions), are particularly useful to make electronic screen-printable materials and electronic components. A group of hydrophobic epoxies (and soluble polyimides) was discovered to be particularly resistant to moisture absorption. The polyimide/epoxy pastes made with these epoxies (and these polyimides) may optionally contain thermal crosslinking agents, adhesion promoting agents, blocked isocyanates, and other inorganic fillers. The polyimide/epoxy pastes of the present invention can have a glass transition temperature greater than 250° C., a water absorption factor of less than 2%, and a positive solubility measurement.
