Look at electronic goldmine webs site - I forget the URL right now -----Original Message----- From: Michael Coop (pjm) To: PICLIST@MITVMA.MIT.EDU Date: Saturday, October 25, 1997 3:17 AM Subject: PCB drill sizes... Can any of you let me know the 'typical' drill sizes you are using for your PCB designs. The last time I drilled any boards was about 10 years ago, and I haven't the faintest idea what size the bits were after all these years... The holes that I'm most interested in are - 'Standard' DIL IC pins (no socket) Axial components e.g. 1/8 watt resistors 0.1" male IDC (Berg) headers The application will eventually be on double-sided plated-through fibreglass. I would also be interested to know the pad sizes you are 'normally' using with these drill sizes for 'easy' hand assembly and soldering... Many thanks MC
