Abstract

It is often desirable to have circuit card contact tabs of unequal length so as to permit one contact to always make contact first and break contact last as the card is inserted or removed. When plating such variable length contact tabs, it is not pos- sible to use the prior art continuous electrical bus at the edge of the card which is later cut off as part of final production. This disclosure places plating bus conductor in an area away from the edge of the card. The bus connections are then removed by drilling or milling.
