Silicone caulk can be used as a basic sealant against water and air penetration. In organosilicon and polymer chemistry, a silicone or polysiloxane is a polymer composed of repeating units of siloxane (−O−R 2 Si−O−SiR 2 −, where R = organic group). They are typically colorless oils or rubber-like substances. Silicones are used in ...
Silicone rubber is an elastomer composed of silicone—itself a polymer—containing silicon together with carbon, hydrogen, and oxygen. Silicone rubbers are widely used in industry, and there are multiple formulations. Silicone rubbers are often one- or two-part polymers, and may contain fillers to improve properties or reduce cost.
RTV silicone rubber can be used to cast materials including wax, gypsum, low-melt alloys/metals, and urethane, epoxy, or polyester resins (without using a release agent). A more recent innovation is the ability to 3D print RTV silicones.
Many-wire ribbon cable was invented in 1956 by Cicoil Corporation, a company based in Chatsworth, California. The company's engineers figured out how to use a new material, silicone rubber, to 'mold' a flat cable containing multiple conductors of the same size. Since the cable looked like a flat ribbon or duct tape, it was named a ribbon cable.
When potting a circuit board that uses surface-mount technology, low glass transition temperature (T g) potting compounds such as polyurethane or silicone may be used. High T g potting compounds may break solder bonds through solder fatigue by hardening at a higher temperature because the coating then shrinks as a rigid solid over a larger part ...
For example, in a chip-on-board assembly process, a silicon die is mounted on the board with an adhesive or soldering process, and then it is electrically connected by wire bonding, typically with 25.4 μm diameter gold or aluminum wire. The chip and the wire are delicate, so they are encapsulated in a version of the conformal coating called a ...
