3.0 Base Board Repair Procedures

The guides in this section detail multiple base board related repairs. It includes delamination/blister correction using injection, bow and twist straightening, and various surface material repairs using epoxy for minor damage repairs and transplants for major repairs. These procedures target structural integrity, dimensional accuracy, and functional reliability, whether correcting warpage, restoring hole integrity, repairing board edges, or replacing damaged material areas. Each method specifies when to use minor versus major repair approaches to ensure proper restoration and long-term durability.
