Thanks to everybody for giving me some manufacturing #'s. > You should use a manufacturer that requests test procedures and will test > the cards for you too, as lost of the faults to be found will be process > orientated. hmm.. the economics of testing and who pays for rejects seems intimately related. Obviously I don't want an assembler with the attitude "we don't know - we put everything in the right place, if it don't work it's you r problem" but I wonder just how much testing I can justify on a little 3-4 chip board, especially since it's not likely to fit easily into digital test equipment, since it's a half analog/half digital board. -- Anniepoo Need loco motors? http://www.idiom.com/~anniepoo/depot/motors.html
