The PCB (Printed Circuit Board) is the physical substrate — the layered fibreglass and copper board — that everything in a phone is mounted on and connected through. Modern smartphone PCBs are multi-layer boards with up to 12 or more internal copper trace layers compressed into a board less than 1mm thick. Physical damage to the PCB itself — cracked board, lifted traces, broken vias — is separate from component failure and requires a different category of repair: micro-soldering jumper wire repairs that bridge damaged trace pathways.
When Is PCB-Level Trace Repair Needed?
- A drop cracked the motherboard, causing multiple functions to fail
- A specific circuit pathway has been identified as open (broken) on a working board
- A component pad was torn off the board during a previous repair attempt
- Water damage has corroded through a trace rather than just a component
- A specific function (e.g., touch, charging, sound) failed after impact with no component fault found
Estimated PCB Trace Repair Costs in Nairobi (2024–2025)
| Repair Type | Labour (KES) | Materials (KES) | Total Estimate (KES) |
|---|---|---|---|
| Single trace jumper wire repair | 2,000 – 4,500 | 200 – 500 | 2,200 – 5,000 |
| Multiple trace repairs (2–5 jumpers) | 4,000 – 9,000 | 500 – 1,500 | 4,500 – 10,500 |
| Torn pad repair + jumper | 3,000 – 7,000 | 500 – 1,200 | 3,500 – 8,200 |
| Cracked board section — partial repair | 6,000 – 15,000 | 1,000 – 3,000 | 7,000 – 18,000 |
| Severe board damage — full board replacement | 10,000 – 55,000 | Included | 10,000 – 55,000 |
Jumper wire repairs on smartphone PCBs use wire thinner than a human hair and are performed under high-magnification microscopes. Success depends on whether the damaged trace is accessible on an outer layer or buried in an inner layer.
When PCB Repair Is Not Viable
Inner-layer trace damage is often irreparable without specialised equipment. A technician will assess the location of the break and advise honestly on whether a jumper repair is feasible or whether board replacement is the only path forward.
Pro-Logic Technologies at Kangari Building, Nairobi is equipped for micro-soldering PCB trace repairs under magnification for a wide range of phone models.
