One thing to try : Pull the Cognex card out and physically re-seat the memory sticks. Then take a kimwipe or something comprable and wipe the card fingers off with alcohol. We have seen this before. You don't even want to know what MPM will charge

there is always risk in rework, multiple heat cycles, overall temp, physical damage, etc... As far as I know the risks are the same with a programmed part as with any other part. If there is great concern or multiple rework actions you may want to

Hi Do you know about some kind of database (library) with physical specifications of the most widely distributed SMD Components. Something like BGA, QFP, SOP, etc. and for each corpus width, length, pins, etc. JEDEC has something similar, but t

Nope, no hour meters on Electrovert OmniFlo series ovens. I concur with Fastek's comments. Never buy a machine without performing a physical inspection. Post question like: What should I look for in an inspection of an OmniFlo oven? First off, it mus

Soldering PTH in reflow makes the process a lot more dependent on the physical forces in soldering (capillary force vs. gravity). Reducing the topheat in your oven will help the capillary forces (opening the hood solved the problem). Heat rises so if

I just noticed that you mention 2-5mm off, that is huge! It would seem to me that there is an external force here to move a part that far. Things such as a heavy air stream that for some reason is really hitting this part, something on the PCB unde

An equipment vendor that is serious about penetrating a market with the physical size of the US will not have a single support/service location. A large infrastructure in my mind means support offices on both coasts as well as something in the middle

Hi Mariss, "water soluable flux residue to somehow damage the X7R capacitors" I think you are looking into the wrong area. Yes flux is aggressive and can lead to problems, however it would not single out X7R capacitors above capacitors of other di

I had the same exact problem recently. I did exactly as the gentlemen said, and reduced the B/S zones 20 or so degrees, AND changed to medium convection. I'd like to point out that the B/S components still go liquidous (such is the Physics of convec

Just wondering if anyone knows this off the top of there head. I might be able to figure out the math based on surface tension (this is 63/37 so the data is out there) but I REALLY do not want to put that kind of effort into this. :/ Editing to clar
