Anyone tried placing domed 1206 LEDs before:

Specialised tool? Some other way?
TIA, Alan
Used to place similarly domed PLCC4 LEDs, to get as reliable operation as possible I countersunk the tip of a Nozzle and then adjusted the device height and Z pick offsets to compensate. I do much the same with our Essemtec machine except it has a Nozzle that shape by default, plus I suspect if I tried it a std one would work anyway. I can't recall the ID of the typical nozzles on the RV, maybe one of them fits quite nicely already?
OK thanks, will report back.

OK ... I ran up a couple of designs - one with a hollow to fit the dome and one with an o-ring (see below). I used the hollow one and as that seemed to work OK-ish I didn't get to use the o-ring one. That worked OK although I had to reset the pick location a couple of times and nudge the finished result around quite a bit. In hindsight I should have locked the pick location as the "pick location adjusting logic" will have been unstable with this shape of nozzle and component. This was all slightly nerve-racking as there were £350 worth and nearly 1,000 of the special IR LEDs on a board :)
