You are right, they are very fiddly to get seated properly. I went for this pitch so I could fit everything onto the more tightly packed boards (RGB Matrix for example). In hindsight, I should have added a few mm, especially to the boards with plenty of space.

I will post a video showing how I do it, as I don’t seem to have a problem with them anymore (having built a bucket load of them). I will post that soonish…
