With some effort, I think you can do better (@marcan42 has used this method with reasonable results which is what gave me the idea in the first place).<\/p>\n\n\n\n<p>They were imaged under the same inspection microscope (Amscope) that I use for soldering. While the images are not great, the feature sizes are huge so it doesn&#8217;t matter so much.<\/p>\n\n\n\n<p>I also purchased some OP177s from Digikey&#8230; turns out that while the packages look kind of fake, the dies appear to be identical!<br><\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1415\" height=\"1752\"
