PL Contactor Electrical Performance

• µHPC/PL contactors provide optimum electrical performance in applications such as wireless communications, low-noise analog, and ultra high-speed logic.
• Two components make up the electrical path through the contactor: a single contact lead of the leadframe, and a portion of the SMM.
• The path length is very short — about 3.5mm (0.140").
• Using the largest-width lead that will operate effectively with the DUT’s lead pitch minimizes inductance.
• Contact resistance is minimized by having all of the components of the electrical path gold plated, and by maximizing the contact area between the contact lead and the DUT lead.
• The density of the SMM wire matrix ensures that the SMM touches the contactor lead and the interface board pad with a large number of conductors, reducing the contact resistance at these points.
• In summary, the ECT µHPC/PL contactor provides yield optimizing electrical performance for a broad range of device types, as well as a robust mechanical design offering long life and ease of maintenance.
