Hi Donovan, I guess it really depends on the product, how it's built and how you'd stress test it. Many arguments can be made about how far to test, then when one fails in the field was it due to manufacturing or test? But the bottom line is most

Yes, pre-loaded feeders is the best way. If you do not have that option as you are high mix or do work for different companies that have many different part numbers, I would guess that your printer will take about 15 minutes to get ready, each HSP f

AOI should not a be a filter at which you throw a mix of good and bad parts to hope it filters out all the bad parts. It shouldn't be seen as a "fix" to the problem of shipping bad parts to your customer. It should be a tool to help you identify wh

It always surprises me how many variations there are for profiling and controlling your ovens, and the thing is most of them are fairly valid. Here's yet another option: Your board profile needs to be specific, 2 boards can look identical but have ve

Well... Some are worse than others... How can you identify that it is caused by uncured mask and not flux residues? The flux is from indium, 3592. Some research in their tech library revealed that either Kyzen or Zestron would work, which is the re

I do want to run a profile, but they won't give up the machine long enough for me to run one. The boards that we are running through the wave are large boards, with large caps, and large transformers on it. We're building highend power amps that

Well, everyone has provided good advice, but if you are looking for a wave flux that can provide much better dwell times and consistent wetting throughout the hole fill, without making adjustments to your production process, I suggest going with Senj

They have been having a lot of fallout and they believe it is one of the BGAs that is causing it. I tell all my customers that it is better to stay away from baking if possible and to practice proper storage techniques. But the thing is they insist o

Dave, Realized I didn't respond to one of your questions. We pasted and reflowed one board, with no components. This board exhibited extreme dewetting on all pads. The board was LF-HASL, and the paste was Qualitek (which we've used for approximat
