Micro SIM Card Connector: prevailing and a widely used SIM solution

The Micro SIM card connector has superseded its predecessors the Mini SIM card connector, and even though we have now a smaller Nano SIM card connector, this 3FF size is still considered a practical solution to many smart devices. The remaining border outside the Chip has enable the Micro SIM card to equip itself with the necessary keying pattern that still assures correct positioning into the device. With backward compatibility with earlier SIM card sizes by SIM adapters, it keeps older devices in operation until it last. While to adapt to Small-Form-Factor design, various adjustments are offered to make the Micro SIM card connector fit product designs.

  • Card Presence Detection Switch

    The Card detection switch is a feature ensuring SIM cards are inserted correctly into the device. This helps to avoid damaging the SIM card which contains the information and other data needed to make a call or identify the user.
  • Robust Design for Manufacturing

    Mounting Posts and Tabs are added to align the SMT solder tails on to their proper positions, these features protect the soldered tails of the MicroSIM card connector from vibration or shock during operation. While high temperature material is chosen for the design of the plastic parts to support soldering processes.
  • Design Customization

    Height, Stand-off dimensions, Pin lay-out and termination arrangement, mounting Posts positions, Shielding coverage, Selective Gold plating thickness and other requests can be evaluated as a Customized feature to fit your Design-in requirements.
