Abstract: A heat block of a wire bonding machine including an inner lead heating part for bonding each one end of wires to each inner lead of a lead frame, a chip heating part for bonding the other ends of the wires to a semiconductor chip, and a differentially heating member for heating the inner lead heating part of the heat block at a relatively higher temperature than that of the chip heating part of the heat block. The heat block of this invention provides advantage in that the chip heating part is heated at a proper heating temperature, at which temperature the semiconductor chip is not injured, while the inner lead heating part is heated at a relatively higher temperature than that of the chip heating part, thereby considerably improving the bonding effect at the bonding portions between the wires and the inner leads of the lead frame owing to the relatively higher heating temperature of the inner lead heating part than that of the chip heating part.

Abstract: The tool is electrically heated and has a flat working surface, essentially horseshoe shaped. The working surface is heated to between 500.degree. F. and 900.degree. F. and pressed for from 3 to 10 seconds against the ground contact surface of a horse's hoof prepared for shoeing. The contact sears the insensitive part of the hoof, the horn, to dry out the horn, seal off the capillary tubes in the tubular of the hoof and flatten any irregularities left on the surface during the preparation for shoeing. This treatment reduces the potential for hoof damage caused by moisture. The working surface is on the horseshoe shaped part which encloses an electrical heating element. The heating element is attached to a handle for the tool. In the steady state heated condition the heat radiated by the tool equals the heat produced by the heating element and no thermostatic temperature control is required.

Abstract: An electrically heated thermode mounts to a support movable to position the thermode for multiple lead reflow soldering and includes a flat resistance element folded on its flat side in a U-shape structure in which the bight portion forms the pressing portion and the legs the terminal portions of the thermode. To overcome a problem arising where a group of joints to be soldered have varying height tops, the way in which the thermode is mounted to the movable support provides freedom of rotational movement of the thermode relative to the support while providing a low resistance electrical connection between support and the thermode terminal portions. To overcome a problem arising because opposite end joints sink more heat than interior joints, terminal plates are shaped and connected to the terminal portions so as to distribute a sheet of current in a way that more of the current flows along side edges than along the interior portion of the U-shaped structure.
