Is there any reason IPC does not offer 4101 to designers at a
discount? I just called and they said I would have to pay the non-member
price.

Regards,

Ted

        I just received a call from our board manufacture regarding
IPC-2221. This is the note I added to the board in the drawings.
2. ALL MATERIAL SHALL BE IN ACCORDANCE WITH IPC-2221, PLASTIC SHEET TYPE
BASE MATERIAL, GLASS BASED PREIMPREGNATED WOVEN E-GLASS WITH A Tg RATING OF
150 DEG. C BASE MATERIAL SHALL MEET UL 94V-0
        I was told that I should have used IPC 4101, I am still new to the
IPC standards and I thought that 2221 called for the board standards of both
fabrication and assembly. Was I too general, is IPC 4101 more specific in
regards to the substraight material, or did I forget to add something to my
notes.

Thank you,
