Copper wire has become one of the preferred materials for wire bonding interconnects in many semiconductor and microelectronic applications. Copper is used for fine wire ball bonding in sizes from 10 micrometers (0.00039 in) up to 75 micrometers (0.003 in). [ 6 ]
Wire binding is a popular commercial book binding method, and is known by various names, including double loop wire, double-o, ring wire, twin loop wire, wire comb, wire-o, wirebind and wiro. With this binding method, users insert their punched pages onto a C-shaped spine , and then use a wire closer to squeeze the spine until it is round. [ 1 ]
Double wire, twin loop, or Wire-O binding is a type of binding that is used for books that will be viewed or read in an office or home type environment. The binding involves the use of a C-shaped wire spine that is squeezed into a round shape using a wire closing device.
In bulk applications, a paper drilling machine may be used. Then the user chooses a spine size that will match the document. Standard sizes are 4.8 mm ( 3 ⁄ 16 in) (for 16 sheets of 20# paper) up to 51 mm (2 in) (for 425 sheets).
Spiral Binding Company, started in 1932, was "the first mechanical binding company in the United States". [2] It created the original metal spiral-coil binding and later the Spiralastic, a popular plastic coil to replace wire during World War II. [ 3 ]
Next the wire is passed out through the capillary and the machine moves over a few millimeters to the location that the chip needs to be wired up to (usually called the leadframe [3]). The machine again descends to the surface, this time without making a ball so that the wire is crushed between the leadframe and the tip of the capillary.
Another type of manual wire stripper is very similar to the simple design previously mentioned, except this type has several notches of varying size. This allows the user to match the notch size to the wire size, thereby eliminating the need for twisting, but can only be used on wire sizes that approximately match one of the notches.
A cable tie (also known as a hose tie, panduit, [1] tie wrap, wire tie, zap-straps, or zip tie) is a type of fastener for holding items together, primarily electrical cables and wires. Because of their low cost, ease of use, and binding strength, cable ties are ubiquitous, finding use in a wide range of other applications.
