Abstract

When terminating resistors having connections to two or more different potentials are soldered into a printed circuit board, some provision must be made to prevent the power planes from being shorted together through the resistors during electrical testing. This can be accomplished by connecting one or more of the terminating resistor power leads to its power source on the back (wiring) side of the board after testing. The signal leads and one power lead can be connected to the internal signal and/or power planes in the usual way by providing lands on the internal planes connected to the plated through holes.
