I forgot to mention something about the local fiducial marks: In the "old days" where board stretch was a factor to count with; the use of local fid's around a fine pitch component was sometimes necessary; not to forget that the pick & place machines

Hi all, I agree with all the postings above, but I have a few ammendmets: (How is my english so far?) The purpose of the so called "local fiducials" was in the old days, when "board stretch" was a factor. At least people think that was a big matter..

| We are using .040" diameter fiducials (global and local) on our boards. They are solder covered and HASL. I get batches of boards where the p&p vision system has trouble reading the fiducial. The fiducial looks dark on the screen. The board ven

You don't say what kind of machine you are using but several just use the edge of fiducials to determine area (and centers). If you are teaching in binary and have the ability to select a decision level (threshold), use a level half way between loss

We have resorted to adding a ring (or donut) around our 0.040" round fiducials. The donut acts as a "plating thief" to minimize the thickness of the copper plating (in the case of HASL finish) and of the solder plating (in the case of solder-plated
