I had some PCBs made with 22 boards per panel (small boards). I\nwanted a single panel for prototypes, but it turned out I could get 6\npanels for only 0 more. This would get me through the first round\nof production if I didn't need any changes. The day the maker was\nsupposed to ship them, I got an email saying they had a poor yield and\nonly got 116 good boards out of 7 panels vs the 132 I ordered.\n\nSo now I have a concern about the quality of the boards. I was told\nthe failed boards had problems with the plating in the 10 mil holes I\nused for vias. They claim that the "good" boards have no quality\nissues. My concern is that the vias may be marginal and open once\nthey are temperature cycled a bit.\n\nI am not sure how to handle this with the vendor. I guess I could\njust flat out tell them that I am concerned with investing some\n,000 building up over 100 boards only to have my customer see\nfailures in the field. I don't feel like they have done 100% on this\nsince they did not provide the quantity I requested.\n\nThey have offered to rebuild the entire set of panels if I am not\nhappy with the result, but that would be a week delay. I also don't\nknow if they are willing to let me use one of the current panels and\nremake the rest.\n\nAnyone have experience with 10 mil via holes and reliability issues?\nIf you have a problem with an order like this, is it reasonable to use\none panel and reject the rest?
