View source for PCB Component Footprint Validation Procedure

=Preparations=

# Install Eagle Freeware edition 7.0.0 (dont use the latest version): http://www.cadsoftusa.com/download-eagle/ and choose "Freeware license" when running it for the first time.
# Download *.brd,*.sch and library archive of a project PCB
# Open the *.brd or *.sch file in Eagle and go to File -> Export -> Partlist
# Save the partlist as text file

=Verification=

==Footprint validation==
# Google for the datasheet of the component with entire partnumber
# Most of the time either the manufacturers website or the distributors (farnell, RS, digikey, mouser) will offer them for download.
# In Eagle go to Library -> Open and select the first library from the archive
# Once the library window opened go to Library -> Package and choose the one matching the one in the partlist
# Now the actual checks begin:
## Check the pitch, position of all pads matches the specifications in the datasheet
## check if all pins are fully surrounded by pads
## check if the pin numbering/naming is matching the datasheet


* for parts that have no value defined check the recommendations and research matching parts
* search for best price offer for this or alternative equivalent parts
