I have had luck at art supply stores. OR you could contact someone like MPM or another printer manufacturer (that way you can pay 5 times what they're worth!!)Sometimes even places like Wal-Mart and such will have this stuff. Russ

K&J Marketing sells a KEPOCH stencil made of polyimide that is cut with a laser. * We have never used them. [We have no relationship nor receive benefit K&J Marketing.] * SMTnet Archives contain threads on them.

I have about 9 Super Bright LED's in my car. I use a 560 ohm Resistor 1/2 watt soldered in-line to the longer lead of the LED. Works fine. http://www.superbrightleds.com

PTH DIP that have been prepped to become SM can be very unreliable, depending on how the part is prepped. Consider asking your customer to do a failure analysis of those solder connections.
