Hi, There are a couple of Omniflow 7 and 7E that are being used in the production. Recently we found a lot of flux clogging up the exhaust ducts. Anybody who uses the same type of tool who has seen this kind of problem? How can we fix this? Does

When we first started we had this problem, we eliminated by longer profile (less delta T) and then ultimately chnaged pad dimensioning for 0402 away from IPC standard. i would highly recommend that you check your placement accuracy and your prof

Thanks for the reply. We have carefully inspected the part and solder joint after depaneling and all looks good. What is weird is if you remove the part from the board and check continuity with a meter you have a dead short. If you put on a new part

I was trying to hide my shame on that one, but we have seen failures that we attributed to moisture issues as well. There was nothing to see with the x-ray, but the BGAs didn't work. Replaced the parts with some that had been properly stored/baked

How accurate is your placement machine? if it is accurate I would eval up to 25% off pad. the problem I might think you will have is errant paste or balls causing shorts if it doesn't coalesce completely. Bottom line is, if the board is good at th
