The carrier bottom has an opening extending partially through the carrier bottom from a top surface thereof and the opening is configured such that when a piezoelectric device to be mounted in the carrier is inserted into the carrier bottom, the piezoelectric device is at least partially recessed within the carrier bottom. The metal contacts include a cantilevered end configured for electrical connection to a piezoelectric device. The carrier lid is configured to retain a piezoelectric device within the carrier bottom and to apply substantially even pressure across a top surface of a piezoelectric device.

  • Publication number: 20140176176
    Abstract: A high bandwidth solder-less lead may be connected to an electrical device having land patterns so that signals on the device may be more easily measured through the lead. The lead includes an attachment mechanism to mount the lead on the device, a microspring housing and at least one microspring. The microspring connects one of the particular land patterns on the device to the lead where it may be easier to couple to a measurement device than to the electrical device itself The lead may be coupled to a flexible electrical conduit to make attaching to the testing device even easier. In other versions, a uniform connector may be temporarily attached to the solder-less lead to test the device. Then the connector may be disconnected from the first lead and connected to another lead to test another area of the device.

  • Patent number: 8737089
    Abstract: A Ferritic stainless steel, non Ferritic stainless steel or carbon steel based lead frame and method for producing same is provided. The lead frame is preferably used for TantalumNiobium capacitors but could possibly be applicable to other integrated circuits with the same operating parameters. Any reference to Tantalum capacitors in this application applies equally to Niobium capacitors unless otherwise noted. The lead frame is prepared by choosing one of Ferritic stainless steel, non Ferritic stainless steel or carbon steel as a base metal and rolling it to a final required thickness. The base metal is then preferably plated with a nickel strike or other conventional barrier layer and then with final outer plating layers(s). The exact thickness and choice of layering varies and can be tailored to meet the requirements of each lead attach process.
