Micro-USB to Type-C Upgrade: Official Procedure

This comprehensive guide presents an official procedure for transforming the Micro-USB charging port of a wide range of electronic devices into the modern Type-C interface. This modification ensures that your device remains relevant in an ever-evolving tech landscape, eliminating concerns about outdated charging ports when acquiring new electronic equipment. Below, we provide a detailed and accessible step-by-step process for this essential upgrade.

Procedure:

Required Tools:

· Multimeter

· Soldering iron, leaded solder, flux paste (preferably with lead)

· AB glue (modified polypropylene resin adhesive)

· Tweezers, screwdriver, double-sided adhesive, small knife

Materials Needed:

· Type-C female connector (surface-mounted, 6 pins), available for around 30 cents

· 0603 SMD resistors, 5.1kΩ

· Fine wires

Procedure:

1. Prepare the Type-C Connector:

· Obtain a 6-pin Type-C surface-mounted female connector.

· Retrieve two 0603 SMD resistors, each rated at 5.1kΩ.

2. Understand Pin Definitions:

· Familiarize yourself with the six pins on the Type-C connector: two ground pins, two positive pins, and two CC (Configuration Channel) pins for Power Delivery (PD) handshake and orientation detection.

· Ensure the two CC pins are connected to ground with a 5.1kΩ resistor to prevent issues with PD chargers.

3. Soldering the Resistors:

· Use flux for smoother soldering. Leaded solder is recommended for better handling.

· Set the soldering iron temperature between 330 and 350 degrees Celsius.

· Connect one CC pin to ground using the SMD resistor.

· Add the second CC pull-down resistor.

· Test the voltage using a C-to-C data cable from a PD charger.

4. Working on the Charging Case:

· Carefully open the charging case with a small knife, exposing the circuit board.

· For some devices, take pictures of the circuit board, disconnect the battery and cables, and remove the mainboard to prevent short circuits.

5. Replacing the Old Connector:

· Apply flux to the old female connector and build up solder.

· Use double-sided adhesive to secure the housing.

· Remove the Micro-USB female connector using the "solder pile" method.

· Clean up excess solder with desoldering wick.

6. Wiring and Insulation:

· Connect fine wires to the ground and positive terminals.

· Clean any remaining flux with alcohol and tissue.

· Apply AB glue to insulate the fixed area and wait for it to cure for five minutes.

· Clean off any remaining flux with alcohol for better adhesion.

7. Fixing the New Connector:

· Apply a thick layer of AB glue to secure the connector.

· Trim the flying wires and expose the copper strands.

· Connect the positive wire to the positive pin and the negative wire to the shell of the connector.

· Insert a data cable and test for power.

8. Final Assembly and Testing:

· Adjust the housing as necessary.

· Reassemble the device.

Conclusion:

In summary, this procedure offers a reliable and officially endorsed method to upgrade the power supply of Micro-USB devices to the versatile Type-C interface. This modification ensures efficient charging (up to 5V 2A) and future-proofs your device for ongoing technological advancements.
