I would suggest getting a copy of IPC-SM-782A, Surface Mount Design and Land Pattern Standard, and IPC-7525 Stencil Design Guidelines. My experience is that reflow does not cause tombstoning very often. Pad and land design, paste volume, and placemen

Indeed, back in 2010 or so I had quotes for a MY100 with a Hydra head,as part of that I did get them to run a theoretical build time for one of our own boards. That came back @ just under 7k cph, it was a pretty sensible board with a nice range of th
