For very high currents in electrical apparatus, and for high currents distributed through a building, bus bars can be used. (The term "bus" is a contraction of the Latin omnibus – meaning "for all".) Each live ("hot") conductor of such a system is a rigid piece of copper or aluminium, usually in flat bars (but sometimes as tubing or other ...
An unassembled IKEA flat-pack stool. Ready-to-assemble furniture (RTA), also known as knock-down furniture (KD), flat-pack furniture, or kit furniture, is a form of furniture that requires customer assembly. The separate components are packed for sale in cartons which also contain assembly instructions and sometimes hardware.
Flat bars are the standard handlebars equipped on mountain bikes, hybrids, and recently on fixed-gear bicycles and flat bar road bikes. A flat bar is a nearly-straight tube, in most cases slightly bent toward the rider. Many penny-farthings and early safety bicycles had flat handlebars.
In applications where vibration or rotation may work a nut loose, various locking mechanisms may be employed: lock washers, jam nuts, eccentric double nuts, [1] specialist adhesive thread-locking fluid such as Loctite, safety pins or lockwire in conjunction with castellated nuts, nylon inserts , or slightly oval-shaped threads.
Nylon 66 (loosely written nylon 6-6, nylon 6/6, nylon 6,6, or nylon 6:6) is a type of polyamide or nylon. It, and nylon 6 , are the two most common for textile and plastic industries. Nylon 66 is made of two monomers each containing 6 carbon atoms, hexamethylenediamine and adipic acid , which give nylon 66 its name. [ 1 ]
The drivetrain of a flat bar bike often borrows features from multiple bike styles, pairing the trigger-shifting approach of mountain bikes with the taller cassette ratios of road bikes. The brakes of purpose-built flat-bar designs tend to be linear-pull, a mechanism nonexistent in road bikes and largely displaced by discs with mountain bikes.
Hot-bar reflow is a selective soldering process where two pre-fluxed, solder coated parts are heated with a heating element (called a thermode) to a temperature sufficient to melt the solder. Pressure is applied through the entire process (usually 15 seconds) to ensure that components stay in place during cooling.
Flat no-lead is a near chip scale plastic encapsulated package made with a planar copper lead frame substrate. Perimeter lands on the package bottom provide electrical connections to the PCB . [ 1 ] Flat no-lead packages usually, but not always, include an exposed thermally conductive pad to improve heat transfer out of the IC (into the PCB).
