Impedance matching networks are electrical circuits which, when connected between two networks, match the output impedance of the source (the first network) to the input impedance of the load (the receiving or second network).

Thin film equipment uses vacuum processing for the modification of surfaces using CVD, PVD, plasma etching, and thermal oxidation or ion implantation.

Coating equipment is used to apply organic, inorganic or metal coatings onto part surfaces for industrial applications.
