Graphite is an allotroph of carbon, gray black, opaque solid, melting point of 3652℃, boiling point of 4827℃. Solid carbon graphite block, a stable chemical property, is corrosion resistance, and is hard to react with acid, alkali and other agents. Carbon graphite block burns in oxygen at 687℃ to form carbon dioxide. It can be oxidized by strong oxidants such as concentrated nitric acid and potassium permanganate. The graphite carbon block also can be used as an antiwear agent or lubricant. High purity graphite as a neutron decelerating agent in the atomic reactor, can be used to manufacture graphite crucible, electrode, brush, dry cell, graphite fiber, heat exchanger, cooler, arc furnace, arc lamp, pencil core, and so on.

Graphite blocks for sale / graphite block for sale are generally divided into natural graphite blocks and artificial graphite blocks. The most widely used ones are artificial graphite blocks. As one of the biggest graphite blocks suppliers/manufacturers in China, WH Graphite can provide you with all kinds of OEM graphite blocks as you need.

Ball Grid Array (BGA) assembly is a crucial process in the manufacturing of electronic devices. With the increasing demand for compact, high-performance electronics, understanding BGA assembly is essential for anyone involved in electronics design and production.

Graphite crucible for melting gold/silver/aluminium/copper/metal uses graphite as the main raw material and plastic refractory clay or carbon as binder processing. This kind of graphite crucible for melting copper is mainly used for gold, silver, copper, aluminum, brass and other non-ferrous metal and alloy smelting. Graphite crucible's wall is smooth and the melting loss of precious metals is small.

A ball grid array (BGA) is a type of surface-mount packaging (a chip carrier) used for integrated circuits. BGA packages are used to permanently mount devices such as microprocessors. A BGA can provide more interconnection pins than can be put on a dual in-line or flat package. The whole bottom surface of the device can be used, instead of just the perimeter. The traces connecting the package's leads to the wires or balls which connect the die to package are also on average shorter than with a perimeter-only type, leading to better performance at high speeds.

PCBs with a copper thickness of more than 70um are called thick copper PCBs, sometimes also called thick copper PCBs. Copper thickness typically varies from 105 to 400 µm. The thicker the copper, the higher the power dissipation of the board. These thick copper plates are used for high current output and improved thermal management. Thick copper makes it possible to create boards with cross-sections for high current loads, which also facilitates heat dissipation. Greenstone is one of the China heavy copper pcb manufacturers which can provide the most professional products and services.
