ABSTRACT:
A shield is provided that blocks high frequency EMI (electromagnetic interference) from reaching circuitry that is connected to pins of a filter connector. The filter connector includes a plurality of pins (12) that extend through holes (92) in first boards (26), with each pin joined by a solder joint (90) to a signal trace (32, 60) that surrounds the pin hole. Filter components such as capacitors (40), each have one terminal (44) joined to a signal trace and another terminal (42) joined to a ground trace (30), with a gap (62) between the traces. Second boards (75) are provided that each lies facewise adjacent to a first board and that each carries a shield trace (72) that covers the gap between signal and ground traces. The pin-receiving hole in each second board has a circular portion and has a notch (100) therein though which a solder dispenser (102) can fit to dispense solder directly into the space between and on the pin and the signal traces.
