Abstract: The present disclosure provides for attaching and embedding a capacitance or a resistance directly in an adaptor board or an interposer board that is then connected to the main circuit board. The adaptor board can be connected to the main circuit board by soldering, electrically connecting it by a conductive elastomer connection, spring pins or by any other way that is known in the art.

Abstract: The present disclosure relates to embedding a power modification component such as a capacitance or a resistance inside of pads that are located to extend over and beyond the vias of the PCB so that a portion of the pad containing the embedded capacitance or resistance is located beyond where the vias or blinds are located. Each of the pads will include an opening that is located over a given one of the vias or blinds to permit that via to conduct through the opening. In this way the capacitance and the resistance will have a closer contact point the electrical component.

Abstract: A method for detecting failed back-drills in PCBs in the process of fabricating a PCB so that the failed back-drill can be screened out or repaired. short to ground connection is added for every back-drill via that will be cut when the back-drill removes the via stub. If the back-drill is bad or failed the short to ground will fail the subsequent electrical tests. The PCB can be repaired by re-drilling the hole or via. Failed back-drills may be detected in the manufacturing stage using standard equipment and test procedures. This process creates a simple pass-fail measurement that uses an existing common test process to catch failed back drills in the PCB fabrication facility. This allows for easy and cost-effective repair and guarantees back-drill failures do not pass into the field.

Abstract: The present invention provides for a structure and a mechanism by which by utilizing additive manufacturing processes electrical connections are created that connect the top and bottom of a block in a customizable pattern. Specifically connection points can be created on the surface of the block and route them to alternate locations transforming the original pattern to a smaller, larger, or alternate pattern.

Abstract: The present invention provides a method for detecting and adjusting failed back-drills in PCBs in the process of fabricating a PCB so that the failed back-drill can be screened out or repaired. This is accomplished, by after detecting poor back drills in a PCB, measuring the actual thickness of each PCB board. Next, the measured actual thickness of each PCB board is compared with .the theoretical thickness of each PCB board. The back drill depth for each area of the PCB board is then adjusted for its theoretical thickness and percent variation from the measured thickness to adjust the poor back drill.

Abstract: The present invention provides a novel method of constructing a coax spring-pin socket that furnishes better performance and is easier to manufacture in volume using common dielectrics and copper plating. This is accomplished by, in application, a lamination of PCB dielectric layers. This dielectric block is then drilled, plated, etched, and drilled in steps for the construction of a coaxial structure for the signal pins, and a ground structure for ground pins. This design process that can be quickly adjusted and customized for each design.
