Micro and signal wire-to-board connector solutions

Initially designed for consumer handheld devices, Molex microminiature and wire-to-board connectors are now being used in applications across many industries. Companies are looking for new ways to use technology to reach and engage with customers. These new application features have translated into a need for more modularity and increased flexible printed assemblies to meet these requirements.

Key application trends across all industries are now increasing the need for micro connector solutions. Molex SlimStack Board-to-Board Connectors, Easy-On FFC/FPCs, and Wire-to-Board Connectors are designed to provide:

  • Increased user interface
  • Feature-rich options
  • Profile change flexibility

In turn, feature-rich options and increased user interfaces result in:

  • Increased flexible printed assemblies to board connection points
  • Modular design (multiple PCBs designs)


The functional sophistication and digitalisation of cars is reulting in increased data and power transfer requirements. With the advent of autonomous driving and newer infotainment technologies, board space in applications such as LiDAR and radar devices, and built-in LCD panels is at a premium. Molex's micro and signal connectors are an ideal solution to these challenges. Discover how they can improve your designs in this webinar with Molex's Brad Eissler, hosted by engineering community element14.

Ideal for compact applications in the automotive, industrial, medical and mobile device industries, SlimStack Board-to-Board Connectors offer a wide selection of low-profile, narrow width options in various mated heights and circuit sizes.
