Abstract
Apparatus (16) for cleaning or lubricating inaccessible pin arrays of an electrical interconnection backplane (10). A connector block (18) with contacts removed is mounted on the end of a dummy circuit board (17). The connector block (18) is slotted across the contact chambers (20), the slot (21) having an absorbent element (24) fitted therein. The element (24), which may be of a polyurethane foam, is saturated with a cleaning or lubricating agent. To clean or lubricate the pins (11), the dummy board (17) is fitted between the guide frames until the backplane pins (11) pierce the absorbent element (24), the latter being 'selfhealing' when the appartus is withdrawn.
