| 1. | Clean the area. Caution Surfaces to be coated must be thoroughly cleaned prior to coating to ensure adequate adhesion, minimized corrosion, and optimized electrical properties. |
| 2. | If needed, apply Kapton tape to outline the area where the soldermask will be applied. |
| 3. | Mix the epoxy or replacement coating. If desired, add color agent to the mixed epoxy to match the circuit board color. |
| 4. | Apply the replacement coating to the board surface as required. A brush or foam swab may be used to apply and spread the epoxy or replacement coating. (See Figure 1). |
| 5. | Cure the epoxy per Procedure 2.7 Epoxy Mixing and Handling. Caution Some components may be sensitive to high temperature. |
| Evaluation | |
| 1. | Visual examination for texture, color match, adhesion and coverage. |
| 2. | Electrical tests to conductors around the repaired area as applicable. |
