Nov 23, 2019· Wire electric discharge machining (WEDM) has become a widely accepted electrothermal process for electrically conductive materials. Still, it puts a certain restriction that the limiting criteria of electrical conductivity should be 0.01 S/cm. To overcome this limiting criterion, a copper foil is applied over the workpiece surface.

While silicon has high resistivity at room temperature, wireless infrastructure generally operates “hot.” At high temperatures, silicon is conductive, and RF coupling to the substrate can occur. When it is cooled, the GaN will shrink more than the silicon substrate. With this, some RF power to the substrate is lost, decreasing efficiency.
Syalon 501 is a composite grade silicon nitride based sialon ceramic developed to provide an electrically conducting advanced ceramic with the traditional silicon nitride properties of high strength, toughness and hardness.
