Well... I don't think that anyone noticed this before. (I only did after
reading line by line... slooooowly.)
Anyway - we just got one company to toss it back to us - saying that they
cannot do ENIG. (That should've been my first clue something was amiss.)
This is the only board in the 'box' that has this ENIG finish specified.
Another thing that should've been a 'red flag'.
We _will_ go back to the client and ask for clarification... they're just a
bit slow in getting back to us, is all.
I'll tell ya this. They've had us scrambling around here the last few days...
*sigh*
Thanks for yall's input on this.
Regards,
James Jackson
