This type of capacitor consists of tantalum powder pressed into a pellet shape as one “plate” of the capacitor, with the oxide as a dielectric, and an electrolytic solution or conductive solid as the other “plate”. Tantalum does not work harden as quickly as most metals. The clearance between the punch and die should be close to 6% of the thickness of the metal being worked. Tantalum is a metallic element with a bluish tint and excellent ductility. Using the physical vapor deposition (PVD) process, tantalum is “sputtered” onto semiconductor substrates to form a thin film diffusion barrier to protect the copper interconnects. Tantalum is a very dense, malleable metal making it easy to work with similar to gold. The instructions given here apply to metal in this thickness range.
