I need to side mount a standard HC-49/U crystal on a board using double sided foam tape. I am looking for a source for pre-cut foam tape. In prototype runs I have used 3M #4950 foam tape cut to size one at a time. But for production I want it pre-

That size should have been .375 X .25 X .050 thick.

Eldon: From you description, I think 3M makes the stuff you�re talking about. They can give you a source to kiss-cut it to your requirements. Good luck. Dave F

You bought quartz (at DigiKey), which should have 10 pF capacitors, and mounted on a demo board is from JFR - "(..) Load capacitance (CL): Series, 16pF, 20pF, 30pF, or specify (..)" - try changing the quartz capacitors, or check with an oscilloscope
