Spark in printed circuit board spark and spark in pcb perfected

摘要

A printed circuit board (PCB) sparkgap utilizing one or more surface mount devices (SMDs) (210;310) wherein the conductive ends (230;320) and solder fillets (220;320) of the SMDs form one or more conductive electrodes of the spark gap (400) and the SMDs help absorb electrical and thermal energy during an arc-over.
