摘要: Structures and manufacturing processes of an ACF array and more particularly a non-random particles are transferred to the array of microcavities of predetermined configuration, shape and dimension. The manufacturing process includes fluidic filling of conductive particles surface-treated with a block copolymer composition onto a substrate or carrier web comprising a predetermined array of microcavities. The thus prepared filled conductive microcavity array is then over-coated or laminated with an adhesive film.

摘要: The disclosed invention relates to materials and processes for creating particle-enhanced bumps on electrical contact surfaces through stencil or screen printing processes. The materials are mixtures of conductive ink, conductive paste, or conductive adhesive and conductive hard particles (104). The process involves depositing the mixture (108) onto electrical contact surfaces by stencil printing, screen printing, or other dispensing techniques (110). In another embodiment, the ink, paste, or adhesive deposit. Once cured (114), the deposition provides a hard, electrical contact bump on the contact surface with a rough, conductive, sandpaper-like surface that can be easily connected to an opposing contact surface without any further surface preparation of either surface.

摘要: Methods for die attachment of multichip and single components including flip chips may involve printing a sintering paste on a substrate or on the back side of a die. Printing may involve stencil printing, screen printing, or a dispensing process. Paste may be printed on the back side of an entire wafer prior to dicing, or on the back side of an individual die. Sintering films may also be fabricated and transferred to a wafer, die or substrate. A post-sintering step may increase throughput.
