Make a PCB

pcb_firsttry_web.jpg

After the burdensome trip to Mr. Mathis lab we could start to bulid our first PCB. Draw some conducting paths on a self-adhesive foil and cut them out. Put the stencil on a nonconducting surface and spray it with Mr. Mathis paint. Remove the stencil carfuly and add some LED’s to it to make sure that it works. More pictures after the jump.

    Im very interested in your projects and especially the “Mr. Mathis paint”.
    Could you please tell me the product name for this or the recipe to make it myself?
    Any assistance will be most appreciated.
    Thanks.

    Unfortunately I don’t know the exact product name. We got a bucket from a local company that does EMF shielding. You just have to search for a conductive paint.
    Have a look at this instructable: http://www.instructables.com/id/Electro-Graf/
    There is also a spray called EMV 35 from Kontakt Chemie that should work too.
    Good luck.

    Very cool! How are the LEDs mounted? Some sort of conductive adhesive?

    Hi Jason

    I just soldered them to the paint. It worked.
    It was also possible to use the paint as glue.
    This workes well for SMD parts.

    I wonder if you could etch the glass and the use a sqeegy to squeeze the paint into the gooves, then sand the surface to take off any residual paint. Probably work better on a not so shiny surface unless you have extremely fine sand paper.

    There’s my random thought of the day. 🙂
