According to exemplary embodiments, a tapered surface interconnect is formed on a printed circuit board (PCB). A compliant pin of an electrical connector may be coupled to the tapered surface interconnect and soldered thereto. The surface interconnect may be formed by drilling through one or more layers of the PCB. The depth of the surface interconnect may be shorter than a height or a thickness of the PCB. The surface interconnect may have a tapered side wall to allow for a better fit with a tapered compliant pin. The inclination of the side wall of the surface interconnect may be linear or concave. The intersection between the tapered sidewall and the bottom of the surface interconnect may be rounded to minimize pin insertion issues and may allow for easier solder flux evacuation. The compliant pin may be soldered into place upon being coupled to the tapered surface interconnect.

Soldered interconnect for a printed circuit board having an angular radial feature

According to exemplary embodiments, a controlled-depth slot extending into a circuit board is provided. The controlled depth slot may be milled, and may comprise &#xbd; radial plated through-holes to generate a solderable 'D' interconnect feature. The slot may include interconnect features on one to five sides. According to another exemplary embodiment, a circuit board having a depth-controlled interconnect slot is provided in conjunction with one or more solderable technology modules. The one or more solderable technology modules may include memory devices, power devices such as Point of Load Supplies (POLS), security devices and anti-tamper devices, capacitance devices, and other types of chips such as Field Programmable Gate Arrays (FPGAs). The solderable technology modules may be soldered into the slot to secure the modules in the slot and connect the modules to interconnects on the circuit board.
