Abstract: An LTCC carrier composed of thermosetting polymer, woven glass fiber and ceramic has gold over nickel contact pads on top and bottom surfaces and conductive vias therethrough between aligned pairs of top and bottom pads. The vias prevent undesirable inductive paths from limiting high frequency operation of the circuitry. Solder deposits on the top pads attach the LTCC component, which is further secured to the carrier by epoxy, thus improving resistance to thermal stress and mechanical shock. A slot through the carrier body between top and bottom surfaces further reduces thermal stress and mechanical shock. Metallized castellations on opposite carrier sides provide additional surface area for reflow solder joints with the PCB, and a means for visually inspecting the solder joint quality. A gap in the metallization on the top layer of the carrier prevents solder spreading during multiple soldering cycles, which may result in poor solder joints.

Abstract: The wrench adaptor of this invention provides an easy and convenient tool for connection and disconnection of the SMA connections in constrained spaces while allowing use of a standard torque wrench or just fingers. The channel design of the wrench adaptor, accommodating the cable and the protective sleeve therefor, allows access to SMA connectors without bending or disturbing semi-rigid or rigid cables. The wrench adaptor is shown in two embodiments—a single-ended and a double-ended form. The adaptor facilitates access to the hexagonal nut at the panel of an RF device which is mounted to a threaded stud and offsets the wrench application to a location away from the panel. As many of the RF cables have crimped or soldered portions adjacent or within the connector, provision is made in the adaptor by way of a hollow semicylindrical form to cradle the semi-rigid or rigid cable.
