Didn't think of tape. I can see it being a bit tedious, as you pointed out, how to apply it without either squeezing out the paste or just moving the part out of place. And while using glue might be a possibility, I'm still faced with the issue that I'm doing these with a skillet, which would means placing the parts right onto the hot plate. I'm thinking I'm going to need to get an oven with top and bottom elements that are individually controlled. If I only use one element the second time around, I can keep one side cooler, while reflowing the other ... I think.
