Thin Film Processing

Cobham MAL Ltd. has retained a thin film processing capability at its Milton Keynes facility for over 25 years. This well developed and regularly used process has been exploited by Cobham in its microwave assemblies and has been qualified into a number of aerospace, defence, communications and space products.

The advanced processing capability enables processing of a large range of materials and Metallisation. Previous designs have seen circuits fabricated on a number of substrates including Alumina, high performance/high dielectric Ceramics, Glass, Silicon, Ceramic-Silicon-Carbide, and Synthetic CVD Diamond. Metallisation schemes include Titanium/Tungsten (TiW), Gold, Platinum, Silver, Nickel, Titanium and Chromium with Tantalum Nitride Resistors and plating of Gold, Nickel and Copper. Circuit features include track widths to 10µm, integrated resistors, plated and filled via, diced to the required final circuit size or laser profiled.

The processing capability in Milton Keynes has been developed to include processing of Glass Microwave Integrated Circuits (GMIC) unique in the UK to Cobham MAL Ltd. GMIC gives a proven, repeatable, higher frequency technology with the added benefit of improved thermal performance and the inclusion of integrated capacitors and inductors. To find out more, please view the GMIC data sheet.

From small quantity prototype production to full production quantities, Cobham MAL Ltd. will be happy to discuss your requirement.
