Hey folks, What's considered Best Practices for TO-92 packages?
I'm working on a project that involves a lot of discrete transistors in TO-92 packages -- the regular style, 3 in-line, no fancy triangular pinouts or lead forming or anything.
The TO92 package in pcblib-newlib seems to be larger than necessary, in pin spacing, pad size, and hole size.
Pin spacing: The actual package has the pins 50 mils apart. Is this used in practice? Or is it too problematic, and maybe it's more practical to just spread the leads a little by hand? Are there machine insertion issues? (Not that I care right now, but I'd like to be as uptown about it as possible.)
The TO-92 leads are 20 mils diameter. Would a 24 mil hole be fine then? And maybe a 35 mil pad?
Anybody have success (or failure) stories or advice? -- Don -- Don Tillman Palo Alto, California d...@till.com http://www.till.com _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
