What the Service Includes
The service includes diagnostics of the specific port (continuity/short check, oxidation, mechanical damage), desoldering of the old jack (hot air or controlled soldering iron), pad cleaning from solder residue and oxidation, selection of a compatible replacement (USB 2.0/3.0 Type-A, USB Type-C 3.1/3.2/Thunderbolt, combo 3.5 mm CTIA/OMTP audio), professional soldering with flux and quality solder, short-circuit verification, load testing (flash drives, chargers, headphones, microphones), and repeated connect/disconnect stability check. Often combined with laptop repair or liquid damage cleaning.
When the Service is Needed
Replacement is needed for unstable flash drive/mouse/external drive connections (intermittent dropouts, slow speeds), complete USB port failure (no phone charging, no device recognition), inability to use headphones or microphone (no audio output, mic not working or crackling), physical port damage (loose/wobbly/stuck plug), oxidation after liquid exposure, sparking or heating during charging. Issues typically arise after 2–5 years of heavy use, frequent plugging/unplugging, dust/liquid ingress, or mechanical stress. In Khmelnytskyi we advise prompt jack replacement to prevent further motherboard trace or USB/audio controller damage.
Work Stages
- Diagnostics: Multimeter check of each port (open/short, oxidation), testing with various devices (flash drive, charger, headphones, mic), visual inspection for mechanical damage and oxidation.
- Disassembly: Full or partial teardown for motherboard access (bottom cover removal, battery disconnect, keyboard/touchpad removal if needed), step documentation.
- Old jack removal: Desoldering with temperature-controlled hot air or iron, pad cleaning with isopropyl alcohol to remove solder residue and oxidation.
- New jack installation: Selection of matching port (USB Type-A 2.0/3.0, Type-C with PD/Thunderbolt support, combo 4-pin/3-pin audio), precise soldering with flux, contact verification with multimeter.
- Reassembly: Component reinstallation, cable reconnection, short-circuit check, screw tightening.
- Testing: Multi-hour port load testing (charging, data transfer, headphone audio, microphone recording), repeated connect/disconnect stability verification.
