- | * **" | + | |
- | * //Potential issue:// Baths 1 and/or 2 are low.\\ | + | |
- | * Lift the lids to baths 1 and 2. If they are low, get a PI/ | + | |

- | * **Zero plating current error during plating step (Bath 5)** | + | |
- | * //Potential issue:// Too much copper buildup on the PCB holder.\\ | + | |
- | * Put on the chemical safety gear (apron, goggles, gloves, in that order) and remove the board from bath 5. Using the drip tray, go to the sink and rinse the drip tray, board, holder, and gloves well. Remove the board from the holder | + | |
- | * If the error continues to be triggered, the resistance remains high, or you are not comfortable doing this, please get a PI. | + | |
- | * //Potential issue:// Insufficient contact between the metal pegs in the tool and the metal underside of the tool holder. | + | |
- | * While wearing the chemical safety gear, make sure that the tool holder is completely screwed down onto the pegs. | + | |
- | * If the toolholder screws will not tighten further but is not in contact with the rail (i.e. there is a gap between the tool holder and the metal side railings), attempt to re-seat the holder onto the pegs While wearing the chemical safety gear. | + | |
- | * If that is unsuccessful in solving the issue, while wearing the chemical safety gear, remove the board+holder from Bath 5 and, using the drip tray, move to the sink to rinse the board, holder, gloves, and drip tray. Remove the board from the holder with the allen key. Using a wire brush, sandpaper, or other means, clean out the peg holes in the tool holder. This may require disassembly of the holder entirely. To test the connection, make sure to don the chemical safety gear again before slotting the holder (without the substrate) into Bath 5. Using a multimeter, measure the resistance between the posts on the holder to the metal rails; this should be below 1 ohm. Rinse the holder when you remove it from the Bath while wearing the chemical safety gear. | + |
