TYPE-C Power Extraction and Adapter Tool Tutorial Based on FPC Flexible Circuit Board

This project involves a TYPE-C interface adapter module with a 5.1kΩ identification resistor. When connected to a power-supported device, it can extract 5V from a C to C cable and provide a USB data line, enabling the conversion of USB 2.0 A-type devices to a TYPE-C interface.

1.Components : Specifications/Remarks

2.FPC soft board : needs to be cut according to the design drawing

3.Type-C interface : 16pin patch type (fixed column needs to be polished)

4 . 5.1k resistor 0603 package: 2 pieces

5. Welding tools soldering iron: solder paste, flux, etc.

Take a piece of FPC flexible circuit board and cut along the white line on the front of the board.

Take a 16-pin surface-mount TYPE-C connector and sand down the four mounting pillars on both sides to make soldering easier. I used 400-grit sandpaper for sanding. Be extra careful not to damage the pins while sanding.

The left side is before sanding, and the right side is after sanding.

Apply solder to the FPC board and proceed with soldering.Note: Using a soldering stencil is not mandatory. If your manual soldering skills are good, you can directly solder the TYPE-C connector, but this may require some expertise.

1. First, solder the sanded TYPE-C connector.

1. Pay special attention to the 16 pins and 4 mounting pillars to ensure proper soldering and avoid solder bridges or cold joints.
2. Finally the 16 pins and 4 mounting pillars to ensure proper soldering and avoid solder bridges or cold joints.
3. Finally, solder the two 5.1kΩ resistors.

After soldering, carefully check for any soldering defects to ensure the connections are secure. Then, clean the board, and the assembly is complete.

The image below shows the board extracting power normally and demonstrates the excellent flexibility of the FPC board. This FPC from jlcpcb . Now they also support transparnet pcb ,with the coupon only : $5.8 .
