S9 ORIGINAL CHARGING RIBBON

What is the “charging ribbon” (charging flex) for S9

• It’s a small flex / ribbon cable assembly inside the phone that includes the USB‑C charging port (female socket), sometimes with microphone, coax lines / antennas, and small passive components (resistors, capacitors, ESD diodes, etc.).

• It connects to the mainboard via a flex connector, carrying power (5V, higher voltages under fast charge), ground, data (USB D+/D–), and other signals.

• In many repair/dismantling parts listings, it’s called “charging PCB flex / charging board / charging port flex cable / lower flex board / USB‑C dock flex.”

Sample Replacement Parts

Here are a few sample listings of replacement charging flex parts (not guaranteed original, but representative):

• Charging Port with Flex Cable for Samsung Galaxy S9 (for fast charging & data) smartmobileparts.com

• Original Charging PCB Complete Flex for Samsung Galaxy S9 Plus (USB‑C port + mic + flex) mobicarenepal.com

What to Check / Verify When Buying a Replacement

1. Model variant match — Ensure the flex is for the exact S9 variant (for example SM‑G960F, G960U, etc.), because flex layout and connector keyed positions differ.

2. Quality / OEM vs aftermarket — Ask for OEM / original marking or compare with the original board flex (e.g. serial codes, part numbers).

3. Components included — Some flex ribbons omit microphone or ESD parts; others include them fully.

4. Port durability — Good replacements use higher quality metal shell, better soldering, support for repeated plug cycles.

5. Test before full reassembly — After solder / connection, test that charging, data sync, and audio (if mic included) work before final sealing.

6. Fast charging support — Ensure the replacement can carry the required current and voltage without excessive voltage drop.
