ABSTRACT:
The external lead from a critical circuit element in a circuit component of a larger apparatus is connected to a first terminal or connector pad on a printed circuit board and at a more distant point on the lead to a second connector pad. The connection to the next element of that component is made from the second pad. Any component output to the next circuit component is connected to the first pad. Thus, any high resistance in a poor solder joint appears on the safe side of the first pad connections, that is, in the circuit connections to the next element or in the output circuit.
