BGA
Ball Grid Array — how chips connect to the Samsung logic board
BGA (Ball Grid Array) is a chip packaging method where all electrical connections are made through an array of tiny solder balls on the underside of the chip. Used for CPUs, RAM chips, Power ICs, and all major controller chips on Samsung logic boards. BGA chips cannot be replaced with a standard soldering iron — removal and installation requires specialist hot air rework equipment and a stereo microscope.
Why It Matters For Your Repair
When a Samsung chip fails, it is almost certainly a BGA component. This is why board-level repair requires a specialist — not just any technician with a soldering iron. BGA work requires proper hot air stations, stencils, and microscope capability. Always confirm your technician has BGA capability before agreeing to a chip-level repair.
