A ball grid array device includes a substrate having a first major surface and a second major surface. The first major surface includes leads for electrical connections. The second major surface is devoid of leads. The ball grid array device also includes a first land having a solder mask opening at the first major surface of the substrate, and a second, buried land near the first major surface of the substrate. A method for forming an electronic device includes forming an electronic circuit in a substrate, placing an input pad for an input to the electronic circuit on at least one major surface of the substrate, placing an output pad for an output from the electronic circuit on the at least one major surface of the substrate, and placing an electrically isolated pad near the at least one major surface of the substrate.

A surface mountable pin connector has a substrate or a circuit board carrier, which has a number of through holes or vias formed therein, and a number of connector pins, each of which is soldered into a respective one of the through holes with high melt temperature solder. A damming device or protrusion is located on each pin nearer to the shoulder than typical interference fit protrusions. The damming device is sized and shaped to completely block the through hole or via.

An integrated circuit cartridge and method has been described. The cartridge includes a heat pipe that comes in thermal contact with at least one integrated circuit die. A spring clip is utilized to provide a compressive force to maintain a substantially even bond line thickness in the presence of opposing forces, such as forces caused by thermal cycling, power cycling, shocks, and vibration. The spring clip can modulate the compressive force applied as a function of parameters on the spring clip. Parameters include load arm width, load arm thickness, load arm curvature, and the location of tabs relative to load arms. A cartridge cover supplies physical protection for pins that protrude from the cartridge. The cartridge cover also supplies key features that aid in alignment of the pins and a socket.

A method for transferring heat away from an ultrasonic medical transducer having a face wherein heat is generated. The method is accomplished by positioning a heat sink behind the transducer face, securing the heat sink to a braided power cable, applying a heat conductive epoxy to the heat sink, and assembling a plastic housing around the heat sink. The transducer face is cooled by conductive heat transfer by transferring the heat into the heat sink, then transferring the heat into the epoxy, then transferring the heat into the power cable and the plastic housing before finally dissipating into the surrounding air.
