High Density Interconnects (HDI)

Reduce overall costs and increase design, layout and construction options

High Density Interconnect (HDI)

High Density Interconnect (HDI) flexible circuits offer increased design, layout and construction options over typical flexible circuits. Each High Density Interconnect incorporates microvias and fine features to achieve highly dense flex circuitry, smaller form factor and increased functionality. This technology offers better electrical performance, access to advanced integrated circuit (IC) package use and improved reliability through the use of microvias and thinner materials. 

Minco’s state-of-the-art facility and equipment can provide you with unmatched HDI features and performance, and our IPC-certified designers can assist you with improving reliability and help make your designs easier to build—without sacrificing performance.

Benefits of HDI

  • Lower cost and smaller size
  • Use advanced component packaging
  • More design options and flexibility
  • Improved electrical performance and signal integrity
  • Improved thermal performance and reliability
