Can anyone recommend software for work instructions? I am using the software with gerbers for through hole and SMT. I have tried Unisoft's software and found it to be difficult to use with gerbers. Is there software that will color code the location

Thanks for your input. Where do I get information about fiducial dimension? Also is there any IPC standard for SMT process?

What is an acceptable mismatch for smt components and pcb. We are having cracked solder joints from fatigue after repeated thermal cycling 25 deg. c to 125 deg.c.

You're correct. So, you're thinking about putting the PTH parts on the same side as the SOIC LED, making the top into the bottom, right?

No, 50 parts on one side and 4 SOIC leds on the other. The LEDs cannot go through the wave so I need to mask them off or cover them up to protect them during the wave.

Don't count out a wave pallet. if the led's are not an extremely tall part a pallet might be just the thing for running something like this at a higher volume.

Rohm make them & call them Backfires: http://www.rohm.com/products/databook/led/pdf/sml-812.pdf The only problem is on some applications you may have to use light pipes.
