A method and arrangement are disclosed for attaching one or more electrical bayonet-type blades to a circuit board with the bayonets being used to receive voltage and current signals from the electric circuit of an electrical meter. The arrangement includes a circuit board with at least one opening adapted to receive one blade. In addition, a sensor is coupled with the electric circuit to sense at least one electrical parameter from the circuit and generating a corresponding analog signal. A solder pad disposed on at least one surface of board surrounds the opening. Solder is applied around the electrically conducting bayonet on one surface of the circuit board and around the electrically conducting bayonet of the surface of the circuit board opposite to the solder pad.
