Re: Through Hole PCB repairs with miniature eyelets:
Commercially available through pcb hole interconnects are available and known as "via's" and are ideal for the repairs as outlined by Argus25.
They are a neat way of linking double sided board tracks where through hole plating cannot be replicated for any reason.
I have previously transferred reclaimed sections of the old single side copper foil track onto a damaged board as suggested by Oldcodger but have used superglue gel in preference to Epoxy but being careful not to inhale the fumes or allow it into my eyes.
