Hi, I would be interested in the data, and I after our experience with batch convection I am quite skeptical. I would be very interested in temperature plots. What I would like to see before I ever considered a batch convection oven is how the oven

Hi, It sounds like your vision is not setup right for this component, and it's rejecting some of them because they would be failing the test. This brings up a point we discovered. Don't use auto teach for the component if your using HYDRA or vision

Thank you Davef, If I am not wrong in understanding, your answer is mainly related to the Legal point of view according to several different Countries who adopted Rohs or equivalent. My question, sorry for my poor English, is mainly related to the

Steve, You are correct in that X-Ray image of a BGA will not show flux residue. So what? If you are using no clean flux then I would think it doesn't matter if there is some flux residue. Sure if you are reworking a BGA and the operator dumps t

OK, I feel the need to jump in here. Bright Tin has the tendency to easily whisker, and is almost never used, except on some through-hole connectors, I believe. Matte Tin is much less susceptible to whiskering, although under the right stress cond

Hi, A second hand TP9-2U MYDATA could be picked up very low cost, however it will only load a single component at a time, which could be ok for your jobs. However if your running 0402, I am not sure if that model will do it accurately. Your machin
