    Abstract: An apparatus to retain an assembled component on one side of a double-sided printed circuit board during reflow of other components subsequently positioned onto an opposite side of the double-sided printed circuit board and methods for manufacturing and using the same. Being formed from an epoxy material, the retainer is configured to be coupled with a component, which is then positioned onto a printed circuit board. During a subsequent solder reflow stage, an ambient temperature surrounding the printed circuit board increases, and the epoxy material is configured to enter a semi-liquid state, flowing onto, and adhering with, the printed circuit board. Upon reaching a typical solder reflow temperature, the liquefied epoxy material is configured to cure or harden, adhesively coupling the component with the printed circuit board. Thereby, the component is inhibited from separating from the printed circuit board when the printed circuit board is subsequently inverted, populated, and reflowed.

    Abstract: An anchoring mechanism and method are provided for securing a component to a printed circuit board. The anchoring mechanism may include a loop, a first leg extending from the loop, and a second leg extending from the loop. The first leg may mount through a first hole of the printed circuit board and include a compressible section to compress when inserted into the first hole and to expand after passing through the first hole. The compressible section of the first leg may support solder between the anchoring mechanism and the first hole. Likewise, the second leg may mount through a second hole of the printed circuit board and include a compressible section to compress when inserted into the second hole and to expand after passing through the second hole. The compressible section of the second leg may support solder between the anchoring mechanism and the second hole.

    Abstract: A method to retain an assembled component on one side of a double-sided printed circuit board. In one embodiment, an adhesive body, in a solid state, is coupled with a component by disposing a coupling member extending from said component within a channel formed in said adhesive body such that the coupling member is engaged with at least one engaging member, said at least one engaging member each extending into said channel from an internal surface defining said channel. The component is then assembled onto a printed circuit board and adhered onto the printed circuit board via the adhesive body when the adhesive body is in semi-liquid state.

    Abstract: An interposer to couple a microelectronic device package to a motherboard is formed from a PCB substrate. Multiple via holes are drilled through a copper-clad PCB substrate and then coated inside with copper. The copper surface coating is etched to form multiple traces. In one embodiment, the substrate is cut through each row of via holes and between each row of via holes to produce multiple individual beam-and-trace interposers. Two or more such interposers may be affixed together to form a beam-and-trace interposer array. Alternatively, the substrate is not cut into strips, and each via hole is filled completely with a conductive material to form an array of solid conductive columns through the substrate.
