Define the contact pattern before platingContact geometry, keying and wipe region belong to the connector interface. Equal spacing in this diagram is illustrative.Define the contact pattern before platingTop view · Equal-width contacts shown for explanationPattern span = (N − 1) × pitch + widthPitchConnector drawing controls:• contact width and spacing• first / last contact location• keying slot and insertion stop• wipe zone and board thickness• mating cycle requirementKeep plating leads, mask and markings outside the agreed contact zone.³Ô¹Ïtv · Engineering illustration · Conceptual, not to scale
