Before assembly, the part is surface mounted to the PCB then using the mass termination tools a range of stranded (14 to 20 AWG) wires can be inserted into the contact slot. This process displaces the insulation and enables the individual conductors of the wire to form a homogeneous joint (IDC termination). The shape of the moulding forms a restraint to the wires insulation when fully inserted in the contact thus strengthening the joint. This process can eliminate the need for hand soldering, cable preparation and lidding. Contact material is phosphor bronze and offers potential for re-termination under certain conditions.
Comments Malcolm Ankers, (Marketing Development Engineer) at AVX: “The 9177 series offers customers the ability to terminate individual wires to a single row of contacts using discrete wire IDC technology.”
