ⅰ) Environmental and market trends continue to discourage the use of cadmium plating. ⅱ) No sacrificial alternative environmentally acceptable plating protection has been identified for aluminium electrical interconnect products satisfying all of the recognised performance requirements: 1. Corrosion-salt spray and aerospace fluids 2. Good electrical conductivity 3. Good temperature performance 4. High abrasion and mechanically damage resistant 5. Good plating adhesion 6. Low friction durable surface ⅲ) This report demonstrates compliance of TTH plated aluminium with the recognised interconnect aerospace performance requirements. ⅳ) TTH offers a proven barrier system protection system for aluminium electrical interconnect products for harsh corrosive aerospace environments. ⅴ) TTH plated 38999 connectors satisfy the requirements of the connector 'bench mark' 38999 qualification standard.
