I am in the same boat.
I have about 10 boards with smt parts that I would like to get done.
The next bunch will hopefully be 100 boards and then after that,
1,000 boards.
I did a little checking and found one guy who will do boards for
something about 25 cents per SMT part and 75 cents per thru-hole
part. yup, a resistor is a thru-hole and yes, I pay 2 cents for them
too.
did more checking...
Outsource to China and the price structure changed to $200 set-up,
$250 engineering charge and two cents per part. that is much better
for the 1,000 board project than the 10 board or 100 board ones.
I also just started looking into silkscreen or template for screening
on solder paste for toaster oven soldering. That starts at about
$75.00 for a metal, laser cut stencil, or I can cut the solder pads
our of plastic with an exacto knife.
Anyone know the thickness for solder paste ?
Alternately, a solder paste dispenser would be a great addition to
the shop.
