Hi MLC, did you profiled the BGA itself? I mean detect Temperatures on middle/central ball vs external ball and see how much is the delta Temperature. Best practice is to keep the delta T at minimum as possible especially on a so large BGA. Sure

I've never had this problem on an Omniflo oven, but have seen it on others. It has always turned out to be mechanical. A bearing going bad or FOD in the rails. I would pull the chains and carefully check each link of both chains, all of the bearin

Using the 120,121,122 series is what you should try first frontlighting. The P Pattern will probably be "4". If this does not work, blacken the background disk (paint) and then use vision type 124. This will give you a great image if the 120 series d
