The logic board (motherboard) is the heart of your MacBook. When it fails, your device may stop powering on, behave unpredictably, or lose important functions. At CTF Repairs, we specialise in advanced component-level logic board repairs, restoring your MacBook without the high cost of a full board replacement.
We diagnose and repair faults down to the chip level using professional tools, microsoldering equipment, and industry-standard testing procedures.

🛠️ Our Logic Board Repair Process

We follow a professional, proven workflow:

1. Full Diagnostic

We test all board circuits:
power rails, voltage lines, I/O controllers, SSD modules, sensors, backlight system, and charging chips.
This identifies the exact faulty component.

2. Microsoldering Repair

Using hot-air rework stations, microscopes, and micro-soldering tools, we:
Replace burnt or corroded chips
Rebuild shorted circuits
Replace power ICs and charging controllers
Repair or replace oxidised connectors
Fix broken traces and backlight drivers

 

3. Deep Cleaning & Reassembly

After the repair, we ultrasonic clean the board to remove residue, corrosion, or liquid deposits.

4. Full Functional Testing

We test:
Power on sequence
Display output
Battery charging
USB ports / Wi-Fi / keyboard / trackpad
Thermals and system stability

5. Quality Assurance

Before handing it back, the machine is tested under stress to confirm stability.
