New SMD practice boards have come, along with some lower temp paste.
I've updated my oven const to run the different heat profile for this paste, I also programmed a slower pre-heat ramp so the solder could de-gas a bit more calmly.
Overall I think the new result is good. There was some bridging on the SOP package, but was easily fixed with an iron + flux. The 0603's are pretty ropey, but I think there was far too much paste for these parts. I think if I had a stencil for these boards, the result would be much better.
