AS&R manufactures Single-sided, Double-sided and Multilayer circuit boards with metal cladding for improved thermal management and grounding. We manufacture high frequency PCBs with metal heatsinks for the telecommunication and aerospace industries. The heat sinks and PCBs are typically connected thermally and electrically. The metal heat sinks help with thermal dissipation and grounding of circuits.
AS&R uses commercially available pre-bonded and post-bonded materials. Pre-bonded laminates are typically supplied by Rogers or Taconic. Post-bonding is done via commercially available sheet film adhesive materials, AS&R’s patented sheet film adhesives or sweat solder. Some of the applications are RF Power Amplifiers, Splitters & Combiners, Complex Filters and RF Power Distribution. Some of the suppliers of laminate / dielectric materials we utilize are: Isola, Nelco, Rogers & Taconic. Metals include Aluminum, Copper, and Brass Composites.

Aluminum Composites
AS&R makes PCBs with unique aluminum composite materials to match the coefficient of thermal expansion (CTE) for various heat generating devices. These materials can match the CTE of ceramics, transistor packages and PCBs. This gives greater flexibility in designs to use lightweight materials and meet challenging environmental requirements.
