I have a problem with fiducials missing on our FAB's when we receive them from the vendor. It is random and not specific to any one assembly.
The boards are being HASL and this is where they are coming off during fabrication. The fiducial size is 0.040" circle ½ oz. Copper. We have other board shops that we use and I haven't had this problem.
Getting to the Question:
The board shop in question asked if we to increase fiducial size or increase copper around fiducial. I feel that this isn't the source of the problem I don't feel that we are asking anything out of the ordinary using 0.040" fiducial. I would appreciate any suggestions in this matter.
Thank you,
ADC
