High Density Interconnect Rigid-Flex allows designers to fold circuits in a 3-dimensional configuration to take advantage of the vertical space within a device. 

Minco’s precision flex circuit technology allows us to specialize in fine  lines, fine pitch, tight tolerances, small holes, lamination, and handling of fine diameter wire.

  • Flexible 3-dimensional packaging – Flex circuits offer unlimited freedom of packing geometry while retaining the precision, density and repeatability of printed circuits.
  • Compact and low mass – Reduce space and weight for optimal packaging and efficiency.
  • Improved reliability – Compliant flex circuit materials minimize stress at solder joints and reduce the number of connection interfaces.
medical device inductive coils


Wire telemetry coil is integrated into a flexible circuit to enable external communications for programming and serves as a secondary dielectric barrier.

  • Inductive coils enable communications telemetry and recharging in medical implants.
  • Flex-CoilsTM and their connections are typically encapsulated inside the laminated flex circuit body, making them less prone to breakage than discrete coils.  No matter the design challenges, Minco engineers bring best practices from hundreds of similar projects worldwide to help our partners plan and design the best solutions for their medical systems.

Flexible Heaters for Medical Equipment

Minco uses a proprietary trimming method for the thin, flexible 384-hole Heater to achieve a tight hole-to-hole tolerance. This allows for almost perfect registration to the microtiter plate.

Thin, flexible heaters consist of an etched-foil (ThermofoilTM) or wire-wound resistive element laminated between layers of insulation material such as polyimide, silicone rubber, mica, polyester or PTFE.

  • Superior thermal performance – Thermally efficient foil elements  transfer heat for greater accuracy, faster warm-up, and increased throughput.
  • Temperature uniformity – Heating elements can be profiled to offset variations in heat loss, ensuring a precise and consistent thermal  system which achieves maximum yield. 
  • Compact and low mass – Thin profile reduces heater space requirements to improve medical device portability while optimizing efficiency. 
  • Flexible geometry – A wide variety of shape, termination and sensor options offer countless design alternatives for any application.
  • Maximum reliability – Minco’s industry leading use of thin, high  temperature materials maximize heater capability and device reliability.

A medical device company was looking to create a highly differentiated solution to quickly cauterize exit wounds in femoral arteries. Using existing technology, wounds caused by the removal of catheters during heart procedures were taking hours to heal. To speed up the cauterization process, Minco integrated a flex circuit with a heater and sensor to create a highly reliable device that was able to reach a target temperature of 100 degree Celsius in less than six minutes. The new configuration not only improves cauterization speed, but it also improves reliability by reducing the number of failure points.
