1) Is it possible that there is another program for the board w/o without the block conversion? Renaming instead of copying the file to a new name is one mistake I won't make again! 2) Are there "notes" in the last column of the placement data? If t

Hi All! I remember reading and seeing some (maybe Loctite) product which could be used to fill stencil apertures, but now when I need one, I cannot find it. Or anything like. Can some one please guide me? And with filling I mean permanent filling, n

Yup, just read that in the link Patrick sent. Thanks again... Im going to have everyone screen the boards for this carefully before processing. I have also sent the board manufacturer an email to get their comment on the matter. No PCB vendor thinks

Josh, You can not check the bare boards for black pad unless you remove the gold plating. Like Robin said black pad is nickel oxidation/corrosion and a result from bad electroless nickel plating bath control. The only preventative action you take is

I have to agree with Patrick here. This image appears to show a board that is NOT HASL as there is what appears to be a copper pad in the upper portion of the image. But then again the arrow tip appears to be white and I woudl expect that to be red s

Need your opinion guys.. The old timers at the plant here feel that we should clean our board after Misprints withe the solvent cleaner over water wash. This is so they don't have to rebake the pcb for 24 hours before smt again. I don't believe th

thk you very much for your fast answers. And yes, I am suspecting the same things also. The problem is to convince the PCB supplier that is his fault. A big fight all the time. SO, i will double check everything you said, and I willl come back with r

I would take the board in question and run it through again with your profiler to verify that no one has messed with your oven recipe, or your oven isn't malfunctioning. Also, a before and after pic attached to the post would probably be helpful to a
