Hi Steve, Both NAS Electronics [718-961-6757] and North Penn Technology [215-997-3200] have a wide variety of add-on leads. Be careful, however; from your query I assume that you are talking about ceramic LCCs on FR-4 PCBs and therefore a large global thermal expansion mismatch. If this is the case, make sure the lead design gives a low enough lead stiffness to meet your reliability requirements. While neither NAS nor North Penn supply the lead stiffness value on their data sheets (at least the last time I looked), I do know that they have them and supply them on request. Also make sure that you are comfortable with the lead material and any overplates on them. Werner Engelmaier Engelmaier Associates, L.C.
