All - I'm looking for supporting documentation for; the typical tooling hole to tooling hole tolerance. I've gone thru IPC-222, 2615, 610 and even defunct D-275 with no luck. Typically I specify +/- 0.003in (or 0.076mm) and sometimes +/-0.002in Any help would be appreciated. SIEMENS Michael Kuczynski Healthcare Diagnostics Inc. Product Eng.
