Dan, I did a job last year in the Boston area doing some DC and RF board combinations on the same structure. Two of the boards had "designed in" inductors. We too had the concern. Worked with the folks at the old Hadco, now Sanmina, and found we had to pay a bit more at first. What really did it for us was negotiating a contract saying that whatever acceptable inductor was found, we would only order production quantities if the same process was used. 600 said/says something to the effect that trace width reductions below 20%, including pits, scratches, dents, etc., shall not be acceptable. No matter, that number or half of it won't do it for printed inductors. Anyway we worked with the supplier and a very good process engineer (Ara Kharajian - Sanmina Tech East Haverhill (978-556-6327)/([log in to unmask])and worked out the requirements.
