• and
• (c) a power supply for sending an electrical current through the conductive solenoid.

A method of deflecting charged particles from striking an integrated circuit package that is located on a circuit board, comprising:

• (a) placing two conductive solenoids into the circuit board, each conductive solenoid having a longitudinal axis, the longitudinal axis of one of the two conductive solenoids forming a right angle with the longitudinal axis of the other of the two conductive solenoids;
• (b) detecting the arrival of charged particles at the circuit board;
• and
• (c) sending an electrical current through the two conductive solenoids to deflect further charged particles away from the circuit board.
