Hi everybody!
Does anybody know how to print on top of the pcb.
(Like you see on electronic building kits, where the components are
marked on top of the pcb)

Great work on setting up one new group Steve :)

Best regards
Thor

Thanks!

You want to do the (usually) silkscreened component
outlines.

You could use toner transfer on the top of the board,
I don't know if it will stick to the fiberglass. Or
you could use a plotter, although that might be fun to
line up.

Try plotting just the board outline on the carrier
paper without the board, then disable the board
outline and plot just the component outlines. Make
sure none of your lines intersect any holes or edges.

If you have a plotter with more than one pen you can
do this in color.

Have a look in the Links section of the group
homepage, I've added some links for Toner Transfer and
using a Plotter.

Hi,
Don't you now any links to sites that explain this with pictures?
and do you know where to buy equipment to do this?

Thanks for the many replies :)

Thor: This is done by "silk-screening". A photographically-

made "screen"

(once made only of silk, but I think, nowadays, some tougher

polyester is

used?) is used as a stencil, and PAINT is "squeegied" onto the

board. The

screen is liquid-tight in areas where you do NOT want the paint,

and only the

"screen" (open weave of the "silk" cloth) is clear, allowing paint

to squeeze

through. This is an "art" which is used in more than just PCB

work! All

kinds of posters, signs, labels, etc., are made by the

familiar "silk-screen"

method.

HOWEVER! If you just MUST have some labelling on the "top" of a

PCB, but

wanna make only ONE, and NOT spend all that for the frame, silk-

screen stock,

developer, squeegie-tool, paint, etc., you can use IMPRESSION

lettering

and/or patterns. Good art-supply stores will have more than just

letters in

that stuff! You want white or maybe yellow, but NOT black, etc.,

as those

colors hardly show on a FR-4 board. Once you have "rubbed off"

your entire

pattern, words, labels, etc., then SPRAY the top with clear enamel

or

lacquer. AFTER you have etched! And be careful not to get any of

that on the

"copper side"! It will look as nice as your steady hand can do

that! I have

done this countless times! Also, for making "professional looking"

panels!

Dial-numbers, ON/OFF, etc. Just SPRAY it after all the rubbing-

off/on is

done!
