Crystalline flux if it is really clear should not be a problem. We were using Amtech paste before and we have the same results. Sometimes we mistakenly see it as a dry joint because of the reflections from the lighting of our Metcal inspection system

I am trying to optimise the use of our Automatic Optical Inspection Machines. As the data we collect from the machine is mainly of the attribute type (Pass/fail, Defect1, Defect2, etc), what advice can you provide to improve its use as well as using

Thanks for the reply Mike, I will look forward to see the end result of your investigation (e-mail people_1@fsmail.net). Regarding the test machines, I was trying to ask what are the suited/or recommended from your experience, set of test equipment

One important thing to look at, when buying an AOI is the False Calls Rate, along with tact time of machine to inspect the PCB. Obviously, many machines can do the the work....but it's also true that each machine differ from the way it do the work. S

1st law of Surface Mount. You WILL run out of parts on the last board going through before a long weekend. 2nd law of Surface Mount. Touchies WILL touch. I'm with Russ and Rob. Touch up is EVIL and should only be tolerated in exceptional circumst

Go inform the owner of your company that you are spending hours of labor dealing with these parts instead of spending the extra 4 dollars it takes to buy an entire reel. When we deal with strips we make sure that an extra amount is ordered to apply

The tendancy always has been "when in doubt, touch it up"... this is not the way to "verify the process" and is not the best strategy for multiple reasons (unessecary rework, additional labor costs, as well as making the solder joint more brittle, [i
