Flex Circuits for Medical Applications

4-Layer Flex Circuit
Tech-Etch specializes in high reliability flexible circuits for Medical Device, Medical Implant, Diagnostic Ultrasound, Telecommunications and Patient Monitoring applications. Manufacturing capabilities include:

  • Adhesiveless construction for thinner and more flexible circuits.
  • Additive processing for higher density circuits. Trace and space capabilities down to .0015" in production.
  • Microvia sizes down to .001" diameter for high density, 2-layer flex circuits.
  • Selective plating of gold and tin lead enables multiple attachment methods on the same flexible circuit.
  • Selective polyimide removal permits cantilevered and windowed leads.
  • Alternate circuit layer materials such as beryllium copper, stainless steel and cupronickel can be used for optimum performance in unique applications.
  • SMT and thru hole assembly services. Package sizes down to 0201 & .4mm pitch.
