What 'board-level' actually means
Most repair = part replacement (battery, screen, keyboard). Board-level repair = fixing individual components ON the logic board itself: capacitors, resistors, ICs, power management chips.
Specialized work requiring microscope, hot-air rework station, soldering at micron precision. Apple itself rarely does board-level — they replace whole logic boards. Independent specialists like AppleForce extend Mac lifespan by repairing what Apple would swap.
When board-level is needed
Liquid damage with shorted components.
GPU artifacts on Radeon Macs (chip reflow or replacement).
T2 chip failures.
Power management chip failures (Mac won't power on, won't charge).
USB-C / Thunderbolt port controller failures (port unreliable).
Audio chip failures (no sound, distorted sound).
Typical diagnostic process (1–3 hours)
Visual inspection under microscope — looking for burned components, liquid residue, corrosion, lifted pads.
Power-on test with current measurements — does board draw correct standby current? Higher draw = shorted component somewhere.
Apple Diagnostics + bootup test — what does the Mac report? Specific error codes.
Schematic-guided probing — using Apple's leaked board schematics + our diagnostic tools to identify failed component.
Typical repair steps
Affected area cleaned (alcohol + ultrasonic if liquid damage).
Damaged component identified via electrical testing.
Component removed (hot air station + tweezers + precision technique).
Replacement component soldered (BGA reflow for chips, hand-solder for SMD components).
Test under bench power supply — verify board boots safely.
Reassemble + full Mac test cycle 24+ hours.
Realistic success rates (AppleForce 2024–2025 data)
Liquid damage cleanup + minor component rework: 90%+ success.
GPU reflow (Radeon Macs): 85% lasting 6–18 months.
Full GPU chip replacement: 70% permanent success.
T2 chip firmware restore: 80%+ success.
T2 chip physical replacement: 50–60% — challenging, high-precision work.
Major liquid damage with extensive corrosion: 40–60% success — sometimes unrecoverable.
Cost ranges
Component-level rework (1–3 small components): PKR 25k–55k.
BGA chip replacement (GPU, T2, major IC): PKR 45k–80k.
Multiple components + extensive cleanup: PKR 60k–150k.
When board can't be saved: PKR 0 (we don't charge for failed attempts) — but recommendation moves to logic board replacement (PKR 100k–250k) or trade-in.
Timeline
Diagnosis: 1–3 days from receipt.
Quote + customer approval: same day.
Repair work itself: 2–5 days depending on complexity.
Post-repair testing: 24–72 hours.
Total: 5–10 days typical for board-level work. Longer than standard repairs because precision can't be rushed.
Why this work isn't always offered
Skill ceiling: most shops don't have board-level capability. AppleForce invested in equipment + training because the demand exists in Pakistan.
Economic threshold: only worth it if the Mac saves significant cost vs replacement. For older Intel Macs at end of macOS support, sometimes we'll honestly say 'trade-in beats fixing.'
