Who repairs integrated circuit boards?

One possibility is the manufacturer of that particular board. Many have repair/exchange programs. If the board itself is physically broken and/or burned, it is probably not repairable. If components on the board are bad, it may be repaired. One possibility is the manufacturer of that particular board. Many have repair/exchange programs.
