Abstract: A method and a structure with multiple implementations is provided that depends on the specific need, for placing (embedding) a serial loopback circuit of known design in a printed circuit board directly beneath the device under test. Micro-vias and traces connect components including transmitter components (TX) and receiver components (RX) that are formed into a loopback circuit for connection to a device under test (DUT). The connection is accomplished by a coupling capacitor with a shortest possible electrical length approximating a straight line between said components and said DUT and said distance is a length of said short straight line times a square root of 2 so that said receiver components are beneath the DUT.

Abstract: A method and an electrical interconnect mechanism in which elastomeric pins are printed onto metal retainer tabs having at least one protrusion or tab extending laterally therefrom to engage a catch or recess of the laminated housing so as to locate each of the elastomeric pins and secure them within the housing. In one embodiment a champher may be employed with a catch or recess to engagely secure a second protrusion or tab extending laterally from another side of said elastomeric pin. In another embodiment the elastomeric pin may have a solid metal ring or a slide collar around the center of the pin wherein the ring has one or two tabs for engaging the recess in the housing and if preferred also the recess of a champfer.

Abstract: Embedding a power modification component such as a capacitance inside of an adaptor board located to extend over and beyond the vias of the main circuit board so that a portion of the interposer board containing the embedded capacitance is located beyond where the vias or blinds are located. This permits that via to conduct through the opening. In this way, the capacitance and the resistance will have a closer contact point to the electrical component. A resistance can also be embedded in an opening in the adaptor board and be vertically aligned within the opening to make contact with a pad on top of the adaptor board and a pad at the bottom of the adaptor board so that electricity conducts through the embedded component.
