Drilled solder paste stencils

Re: [Homebrew_PCBs] Drilled solder paste stencils

Hi, Derek

Can you give more details of the process ? Things like material used for
the stencil, drill sizes, how to fix the plate for drilling, how to fix the
plate for applying the solder paste, down to align the plate and the
PCB..... Those details will be very helpfull for anyone tryong to reproduce
your efforts.. I will surely try :-)

Best regards,
Alexandre Guimaraes

That's rather impressive. Did you do anything special to flatten the
stencil after drilling? (or do you just use sharp drill bits?)

Nice work! Looks like the template was sanded to deburr the holes. Must
be pretty tricky to keep sheet metal flat enough to keep it in contact
with the PCB. I assume you clamp them together and then scrape paste in
each hole with a putty knife of some sort?

Couple the CNC with some thin stainless and
an EDM unit and square holes are on the cards.

Well, yes, you could - but round holes seem to do the job nicely without
the extra pain...

WONDERFULL!
How thick is the brass material?
Did you have the brass clamped between sheets of something? What?

"Sweet" would just about sum up my thoughts on that. Nice work.
