Bonjour Christophe,

Oui, c'est vrai,
Yes the 2220 series replaces 275.
It is updated, refined and expanded, but you will recognise many familiar
elements from 275.

2221 is a generic standard, covering the common issues on all types of boards.
2222 is for Rigid boards.
2223 is for Flex boards
2224 is for PCMCIA
2225 is for MCM-L
2226 is for Discrete Wiring

You will need 2221 as well as the appropriate standard for the type of
boards that you are designing.

regards,
Phil.
(please excuse my high school french)
