Oddly enough, I find it more often than not that the supply type is not mentioned in the data sheets. And if the original author was saying 0603 in a metric package, then it would be in 8x2 tape. Even in the US, some companies use the metric names

Hello Hoss, try with the flux again. I would first change the flux. Alcohol based for me is always better. But you can try water based too. 1. Change the flux 2. Go with more pressure on your atomizer(or whatever they call it on your machine). Just

I have just carried out an evaluation project including Mirtec, MVP, Landrex and Viscom. If you are interested in my findings you can contact me offline. In short though, we found that each had plus points to them. If you could join together the outs
