I'm not sure I understand why the library of modules is in the state it is? I would expect to see module files like SO.mod, DO.mod, DIP.mod, PLC.mod, discreet_SM.mod, etc. Am I missing something?
Anyway, it appears that I should not trust what is in the library anyway. I got a copy of "LP Calculator" to work. should probably be three versions of the modules library for surface-mount work - General purpose - high reliability and very-high density. (There are settings to get these numbers out of LP-calculator). A = Most - reliable - but bigger B = Nominal - mid sized C = Least - very small For others that want to generate these pads - here are the clues From http://landpatterns.ipc.org/default.asp Download this link http://landpatterns.ipc.org/files/PCBM_LP_Calculator_V2009-0831.zip Get Winetricks from: http://winezeug.googlecode.com/svn/trunk/winetricks Save the script Then using a Terminal type in sh winetricks in script directory Select using the GUI dotnet20 and install There is one other detail that should get worked out - there are two ways that cap footprints are specified - and it generates confusion - metric and imperial - thus 0201 (02x01mils) = 0603 in metric (remind me to once again curse the creeps that stopped metrication back in the '60s). Complete list http://wiki.xtronics.com/index.php/Capacitor_Codes#Imperial_and_metric_case_size_codes There are two that overlap - there is are 0402 0603 in both imperial and metric. The library name ought to give a hint as to the units used.. The current lib lists these as SM0603 in imperial.. I'm thinking of creating a metric named lib with 0603M? -------------------------------------------------------------------------------- Karl Schmidt EMail k...@xtronics.com Transtronics, Inc.
