Reflow vs reball
Both procedures involve high heat and risk permanently damaging the board. Practice on a dead motherboard first, and never rush the temperature curve.
Reflow vs Reball
Both repairs target the same problem: cracked solder joints under the CPU and GPU of a phat Xbox 360. They differ in how thoroughly they fix it.
- Diagnose. Confirm the fault is solder-related (three red lights, secondary error codes pointing at GPU/RAM) rather than a blown power supply or DVD drive.
- Choose the method. Reflow re-melts the existing solder to bridge cracks. Reball removes the chip, cleans off old solder, and applies fresh balls before re-seating it.
- Prepare. Remove the heatsinks, clean off old thermal compound, and apply flux. Reball additionally requires a stencil and fresh solder spheres.
- Heat. Use a hot-air rework station or reflow oven following a controlled temperature profile. Avoid a heat gun where possible.
- Finish. Re-seat the chip, apply fresh thermal paste, reassemble, and test to a stable boot.
Which should you pick?
Reflow is faster and cheaper but often temporary; the same joints can crack again within months. Reball takes more skill and equipment but is the lasting fix because it rebuilds the connection from scratch.
