![]() ![]() This gives greater flexibility in designs to use lightweight materials and meet challenging environmental requirements.PTFE Teflon PCB has excellent comprehensive performance: high temperature resistance (-192☌-260☌), corrosion resistance (strong acid, strong alkali, aqua regia, etc.), weather resistance, high insulation, high lubrication, no adhesion, Non-toxic and other excellent characteristics.Īt present, various types of PTFE products have played a pivotal role in the national economy such as chemical, machinery, electronics, electrical appliances, military, aerospace, environmental protection and bridges. These materials can match the CTE of ceramics, transistor packages and PCBs. Discrete PCB to Pre-bond or Post-bond assembly conversionĪS&R makes PCBs with unique aluminum composite materials to match the coefficient of thermal expansion (CTE) for various heat generating devices.Pre-bonded to Post-bonded assembly conversion.Thermally and electrically conductive and non-conductive proprietary and commercially available adhesive bonded laminates.In-house plating and precision machining for finished assemblies.Plated through-hole capability metal carrier to PTFE.Thermally and electrically conductive and non-conductive proprietary adhesive bonded laminates.Metals include Aluminum, Copper, and Brass Composites. Some of the suppliers of laminate / dielectric materials we utilize are: Isola, Nelco, Rogers & Taconic. Some of the applications are RF Power Amplifiers, Splitters & Combiners, Complex Filters and RF Power Distribution. Post-bonding is done via commercially available sheet film adhesive materials, AS&R’s patented sheet film adhesives or sweat solder. Pre-bonded laminates are typically supplied by Rogers or Taconic. The metal heat sinks help with thermal dissipation and grounding of circuits.ĪS&R uses commercially available pre-bonded and post-bonded materials. The heat sinks and PCBs are typically connected thermally and electrically. We manufacture high frequency PCBs with metal heatsinks for the telecommunication and aerospace industries. AS&R manufactures Single-sided, Double-sided and Multilayer circuit boards with metal cladding for improved thermal management and grounding. ![]()
