  • Suggestion: add a grounding wrist strap with alligator clip to the kit, or at least carry one in general inventory. It would simplify the ground path, especially for littler kids. Just put the strap on, and go play.

  • It has the thermal vias and a copper pad, but it’s definitely not as big as the TI recommendation.

    • Add a second row of vias in the exposed pad.
    • Don’t use thermals between the exposed pad and the rest of the topside ground pour.
    • Push a few of the nearby traces out (on top and bottom side) to provide a little more copper for the thermal relief.

    Quick mockup in Eagle:

  • They don’t specifically address it in the web site, but the MSDS says “Materials to avoid: Acids, bases, and oxidising agents”. http://sugru.com/pdfs/FORMEROLsugru_MSDS_Oct09.pdf

  • Original manufacturer data here: http://www.teko.it/en/prodotti/famiglia/PO/serie/68
    Includes their drawing datasheet, a DWG and an eDrawing. Their drawing includes maximum PCB dimensions. The site also has a material datasheet in Italian (spoiler, it’s made of UL 94 rated ABS).
