Step 1: Cutting the FPC Board:

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

Step 2: Sanding the TYPE-C Interface:

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.

Step 3: Comparison Image:

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

Step 4: Soldering

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.

Step 5:

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.

Step 6: Power Extraction Test

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 .
