Abstract
Terminating resistances are provided to at least some pins of an ASIC or other multi-pin component mounted on a surface of a circuit board, by positioning a second circuit board on the surface of the main circuit board substantially opposite, and preferably aligned with or overlapping, the multi-pin component. The second circuit board accommodates a resistor such as a printed resistor, surface mount resistor or buried resistor. Preferably, vias in the main circuit board connect pins of the ASIC to terminating resistors. Preferably one or both of the ASIC and the second circuit board are coupled to the main circuit board by a ball grid array.
