I forgot to add the tolearace reply to my previous post about pricing. Here at AIT, we typically quote a value +/- 10%. This gives the fab guys some room to work and keeps scrap rates down. However, the tolerance would be a function of a given fab house's abilities since the material could be tested and then the resistor size compensated prior to imaging/etching it. -- Robert Blomstrom, DWB Design Advanced Interconnection Technology, Inc. - Atlanta 3289 Montreal Industrial Way, Tucker, Ga. 30084 Phone: 404-938-9387 x226 fax: 404-934-9885 e-mail address: [log in to unmask] PS.
