    摘要: A method and structure for conductively coupling a metallic stiffener to a chip carrier. A substrate has a conductive pad on its surface and an adhesive layer is formed on the substrate surface. The metallic stiffener is placed on the adhesive layer, wherein the adhesive layer mechanically couples the stiffener to the substrate surface and electrically couples the stiffener to the pad. The adhesive layer is then cured such as by pressurization at elevated temperature. Embodiments of the present invention form the adhesive layer by forming an electrically conductive contact on the pad and setting a dry adhesive on the substrate, such that the electrically conductive contact is within a hole in the dry adhesive. The electrically conductive contact electrically couples the stiffener to the pad. The curing step includes curing both the dry adhesive and the electrically conductive contact, resulting in the dry adhesive adhesively coupling the stiffener to the substrate. The electrically conductive contact may include an electrically conductive adhesive or a metallic solder. Additional embodiments of the present invention form the adhesive layer by applying an electrically conductive adhesive on the substrate, wherein after the stiffener is placed on the adhesive layer, the electrically conductive adhesive mechanically and electrically couples the stiffener to the surface of the substrate.

    摘要: A method for aligning a plurality of thin film transistor tiles for constructing a flat panel display. A coverplate is arranged on a coverplate support. A first layer of a bonding material is applied to at least one of a first side of each of the tiles and a surface of the coverplate on which the tiles are to be secured. The tiles are arranged on the coverplate, such that the first layer of bonding material is arranged between the tiles and the coverplate. The tiles are connected to an alignment apparatus. The tiles are aligned relative to each other and the coverplate. The tiles are at least partially secured to the coverplate.

    摘要: A method of making an electrically conductive contact on a substrate by applying a layer of solder paste to a circuitized feature on a substrate and selectively heating and melting the solder paste over the feature to form a solder bump. The excess solder paste is removed. A focused energy heat source such as a laser beam or focused Infrared heats the solder paste. In another embodiment, a reflective mask with apertures may be used to allow focused heating source to selectively melt areas of the solder paste layer applied to a circuitized feature. In yet another embodiment, a reflective mask with apertures filled with solder paste is applied onto a substrate and then heated to cause localized solder melting. The mask and excess solder paste are removed.

    摘要: A stiffener (34 or 52 or 72) includes a pathway which allows gases and fluids, such as air, to be vented from the interface between surface bonding regions (35 or 60 or 74) of the stiffener and an adhesive (38 or 56 or 80) on a flexible substrate (36 or 54 or 78). The pathway may take the form of a porous material used for the stiffener or one or more bore holes (58 or 59 or 70) formed in the stiffener. The stiffener may also include an internal cavity (76) for promoting venting of fluids and gases. By venting fluid and gases from the adhesive/stiffener interface, better adhesion between the stiffener and flexible substrate is achieved.
