Abstract: A raised solder-mask-defined (SMD) pad configured for receiving a solder ball on a laminate electronic circuit board and a method of creating the raised SMD pad on a laminate electronic circuit board. The method may comprise forming a base bump, covering the base bump with a conductive bump layer and layering a surrounding material over an extended edge of the conductive bump layer. The surrounding material is patterned to expose a pad face and of a portion of the sides of the conductive bump layer, such that the pad face is disposed above the surface of the surrounding material. The surrounding material may be patterned by a photolithography operation or alternatively, a laser-drill operation.

Abstract: In a semiconductor flip-chip package having a semiconductor die as part of a substrate assembly, a lid (or lid assembly) and substrate are supported to prevent tilting and teetering of the lid. The lid and substrate do not adhere, so as to reduce cracking of solder joints due to thermal cycling induced by repeated system power on-off. An adhesion prohibitor may be applied so that a support does not adhere to both lid and substrate; the support may be prevented from adhering to both lid and substrate by a separate curing step. The arrangements and fabrication methods may be applied to many package types, including ball grid array (BGA) and land grid array (LGA) packages.

Abstract: Disclosed are integrated circuit assemblies with increased stand-off height and methods and systems for their manufacture. Methods of the invention provide for assembling a semiconductor device by aligning a die with a substrate and interposing solder between corresponding substrate and die bond pads. A lifting force is applied to the die during heating of the solder to a liquescent state, thereby increasing the stand-off height of the die above the substrate. The lifting force is maintained during cooling of the solder to a solid state, thereby forming increased stand-off height solder connections.

Abstract: A system (100) for manufacturing product, in which a first work station (101) is operable to perform a first manufacturing action on the product parts; this first station has a first entrance (101a) and a first exit 101b). A second work station (102) is operable to perform a second manufacturing action on the product parts; this second station has a second entrance (102a) and a second exit (102b). A transport line (103) between the first exit and the second entrance is operable to move the product parts under computer control. A chamber (104) encloses a portion of the line and is constructed so that the transport achieves a balanced throughput from the first station to the second station, while the product parts are exposed to computer-controlled environmental conditions (110) during transport through the chamber. The balanced throughput in the chamber is achieved by waiting lines for the product with computer-controlled monitors (105a) for product parts' positions and times in the chamber.

Abstract: System and method for a polymer encapsulated solder lid attach. A preferred embodiment comprises one or more metallic islands distributed throughout the combination attach, wherein each metallic island overlays one or more heat producing portions of the integrated circuit die, and a polymer encapsulant to encircle each metallic island and to bind the one or more metallic islands in place. The one or more metallic islands, with their high thermal conductivity, can effectively dissipate large amounts of heat, while the polymer encapsulant binds the one or more metallic islands in place, preventing (or reducing) movement occurring during thermal cycles that can lead to delamination and separation.
