PCB Repair Service in Nairobi
PCB — Printed Circuit Board — repair is another term for the board-level repair work carried out on a smartphone's motherboard. The printed circuit board is the physical substrate on which all electronic components are mounted and interconnected — the green, blue, or black multilayer board that forms the structural and electrical backbone of the device. PCB repair addresses faults in the board itself: broken traces, lifted pads, delaminated layers, and physical damage to the board substrate — as well as faults in the components mounted on it.
PCB damage in smartphones is most commonly caused by physical impact, moisture exposure, and electrical stress. Impact damage cracks trace copper on the board surface or on internal layers, breaking signal paths in ways that produce highly specific and repeatable functional failures. Moisture corrodes exposed copper, attacks solder joints, and in severe cases penetrates the board substrate itself. Electrical stress — from overcharging, use with incompatible chargers, or static discharge — can burn component pads and damage trace copper in the immediate vicinity of the affected circuit.
Prologic Technologies on Luthuli Avenue offers PCB repair as a core service within its board-level repair capability. The team is equipped with the tools required for both surface-level and sub-surface PCB fault diagnosis — including continuity testing, thermal imaging to locate abnormal current draw, and microscope-assisted visual inspection of board surface and component solder joints.
Surface trace repair involves scraping the solder mask from the damaged trace, cleaning the copper, and bridging the break with a micro-wire soldered at each end — restoring electrical continuity without affecting the surrounding board. Pad restoration uses specialised conductive compounds to rebuild missing pad metallisation before component replacement.
All PCB repair work is completed with a full functional test before the device is returned.
