A technique is described whereby slot windows are incorporated into circuit card edge connector artwork to provide a means of locating and inspecting critical alignment of keyslots relative to the contact tab locations. Because of the critical alignment requirements, the concept is particularly adaptable to circuit card edge connectors which utilize contact tab centerline spacing of less than 100 mils. Circuit cards, as used in personal systems, typically use extremely narrow centerline tab edge connectors, less than 100 mils, to interface with Micro-Channel* busses. The edge connector generally incorporates a key molded into the connector, to minimize the total contact-to-tab tolerance accumulation.
