- | | + | **Be sure you actually NEED to electroplate before starting this!** The plating process usually takes in excess of three hours (depending on how closely you're watching it), and is historically unreliable. Further, even if it looks like the plating quality is good, the micron-scale variability across the sheet may doom any etching attempts. //There is an alternative!// |

+ | //Quick Plating Tips//: | ||
+ | * Adjusting the plating time can be done if you need a different thickness of copper rather than the standard 18um. If you would like to adjust the plating time, contact the MPIs at < | ||
+ | * Do not let your substrate sit in the bath (any bath) for very long after the timer runs out. | ||
+ | * If the machine throws an error on startup, it’s likely a bath needs to be topped off. Get a PI to help. | ||
+ | * Don't forget to stir bath 3 prior to use! At least 3 minutes, about 200 end-to-end strokes. | ||
+ | * When rinsing after drying (after “bath 4”), scrub the copper surface with a sponge to remove as much of the dried activator off the copper as possible. | ||
+ | * Scour around your fiducials after plating. It makes a noticeable difference to the laser. | ||
