@adonijr not a lot of information here.
The answer to your question could only be, that you repair it.
You need to be more specific as to what type of board damage. Missing or burned components, torn traces, physical damage to the board etc. all get fixed differently. For a specific answer on how to repair your board, you need to let us know what is damaged on it.
The most important part here is that you have the tools and the skills to do this type of repair.
