To answer your question it was mentioned that allowing the boards to cool slightly between reflow and wash may help this case to eliminate thermal shock from immediately going into colder water straight out of the oven with no cooling. In looking at

In-Circuit Test is the best method for ensuring solder joint connections. It is a much more reliable than AOI. An ICT machine can ensure solder connections are made for array package devices such as BGA, PGA, etc... AOI is best for component I.D.- is

I have used all of test and inspection techniques available out there: AOI, AXI, Flying Probe, ICT, and FCT. The reality is that they all have a place in manufacturing based on the type and complexity of product you bild, the industry it is intended

Sorry, I am jumping into this late - I'm a new user. Our company is looking to perform an evaluation for a new paste. We are looking at a 63/37 no clean - type 3 or 4. Our technology is currently at 0201s, .4mm pitch ICs & .5mm uBGAs. I have

Look at: http://thor.inemi.org/webdownload/newsroom/Presentations/09.pdf Page 47 shows both alloys to be similar in reliability although its a little troublesome that the particular defects are not isolated as I feel there is a big difference betwee

Yes, doing the DoEs on your wave to achieve optimum settings that deliver the best results on your worst board is correct method. If not clear on the process, there are still wave solder process classes out there you can attend or hire in-house. If y

Bingo! In my career, I've used Wave Solder optimizer and the WaveRIDER. Pro's and Con's to both. I did a GR&R on both as well, and WaveRIDER came out on top. The main challenge is to get the operators to use it. I've found that the operators wer

I agree with Steve and would hate to have Ken audit me. "Mrs. Chunks, sure your profile looks like the manufacturers recommended spec, your oven is calibrated to the best you can do or afford, your profiler is also calibrated to the best of your cap
