Another use for a CNC drill or mill. Goodbye to hand soldering, syringes and $100 - $150 laser templates. Some after "pasting" and after "baking" shots are at the link below. Click on slideshow in the upper right hand corner. http://www.pbase.com/eldata/stencils&page=all

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,

Did you do anything special to flatten the stencil after drilling? (or do you just use sharp drill bits?) Steve

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?

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.
