Hello, I am having a problem with a large amount of solder balls surrounding mostly the legs of fine pitch ics. There seems to be a large collection in gap between the pad and the solder resist. They do not easily wash out. Our profile seems to be

OK. You used a thermometer to to check your recipe. How do know that the temperatures that you selected are correct? Your solder balls indicates that it's possible that the temperatures that you selected might not be correct. Without belaboring an

I concur with Mr. KaHrpr and Mr. Dave. Just because your measured profile falls in the middle of a process window doesn’t mean that you won’t ever have to analyze it. You may be 9/10ths of the way there, but running 25 miles won't win you a marathon

Thanks for all the input guys! After trying to figure this out in our smt process, we have discovered that the board house did not meet the required pad width for the fine pitched ICs when making the bare boards. Our stencil was cut out to fit the p

There should be a "Tracking" button at the bottom of the screen that you can just tab over to, then press the green start button. I have not worked with the 730, but it is that way on our 740, 750, and 760 machines. Alternatively, you can move the cu

Seika make a solder paste recycling unit that will melt solder paste and separate the solder from the flux. You end-up with liquid flux in a jar and a block of solid solder, which you could re-use in a solder wave if the type is the same.
