Logic Board Microsoldering
The Logic Board is the brain of your Mac. When it fails, most shops say 'it's dead'. We say 'let's look closer'. Using schematics and boardviews, we diagnose and replace individual failed micro-chips, resistors, and capacitors to restore your board to life.
Component Level Repair
Electronics harvesting is an art. A MacBook logic board has thousands of components. Usually, only one or two have failed. Throwing away the whole board because of a 10-pence capacitor is wasteful and expensive.
We Save You Money: A replacement board for a 2019 MacBook Pro can cost £500+. Repairing that board costs £150-£250.
We use professional equipment: Soldering stations, Hot Air rework stations, and Fluke multimeters to troubleshoot complex issues like 'No Power', 'Not Charging', or 'Boot Loops'.
Our Logic Board Services
1. Backlight Repair
Screen dark but you can see the image with a torch? This is a backlight circuit failure (often up to 50 Volts). We replace the driver chip and blown fuse.
2. USB-C / Charging Ports
If your ports are loose or not negotiating fast charging (stuck at 5V instead of 20V), we replace the CD3215/CD3217 controllers.
3. Kernel Panics / Crashing
Random restarts? We analyze the 'Panic Logs'. It could be a failing sensor, bad RAM soldering, or a T2 Security Chip crash.
We Do What Apple Won't
Apple Store Geniuses are not trained in electronics; they are trained in 'swapping'. If a diagnostic tool fails, they swap the part.
We are technicians. We understand electricity. We trace the PPBUS_G3H power rail to find the short to ground.
- Environmentally Friendly: Repairing is recycling.
- Faster Turnaround: We do this in-house in Leeds, we don't ship it to a central depot.
Common Symptoms
Your Board might be failing if:
- Dead: Press power, nothing happens. No fan spin.
- Not Charging: Light on charger is off or green but not turning orange.
- Fan Max Speed: Fans running at 100% usually means a sensor failure.
Frequently Asked Questions
Expert answers.
Is it worth fixing an old Mac?
Usually yes, if it's 2015 or newer. For very old machines, we will advise you honestly if the repair cost exceeds the machine's value.
What is the success rate?
About 85-90%. Sometimes a board has internal layer damage (a hole burned through it) which is unfixable, but most electrical faults are repairable.
