I am looking for images of solder paste defects like Past stringing, paste gorging and dog ears. I would also like to have the avi file to show how tombstoning happens in the reflow oven. Thanks Bob

Hello, I need to convert setup files to an xml-string for Traceability. Therefore I need a description of the fileformat, as it is used internally from the Software.

No dome needed. You should check what type probe you have. You can look here and consult with them: http://www.qualmaxamerica.com/qualmax/leeno/semi.asp?string=ICT

During initial profiling we shoot for 15% or less voiding on our BGAs. During production runs we consider voids under 15% to be ok. Voiding between 15%-25% we string tag and pay more attention to during test. Over 25% we consider a reject.

Like many other circuit assemblers we cross reference an incoming reel of components Manufacturers PN (MPN) to our company’s Internal Part number (IPN). For years I've been scanning the MPN & Qty on the manufacturers label and using a simple database

That's fine for Toshiba but what do you do for other Mfg's with different formats? And how do you resolve the 255 character input limit in Access for Mfg's with more characters in the barcode string like Vishay?

Thanks for your response, I changed the attachment to a PDF. It will be easy enough to set up if we need to do this. I was hoping the test was a little more formal and documented but quick and dirty evaluation have their place as well.

Yes if you adjust the thickness to be thin than the machine raise the PCB more to the stencil - than the foil have better tension but it string out faster.
