The COTSPnP pick-and-place machine (PnP) is used to place surface-mount devices (SMDs) onto a printed circuit board and was designed and built exclusively from off-the-shelf (COTS) components, predominantly sourced from OpenBuilds and Actobotics. Its intended use is prototyping and not high rate, high volume production and is capable of precisely placing parts as small as 0402 capacitors and resistors but more importantly, can precisely place components with lead spacing as small a 0.4mm.

    This looks amazing - nice work Joe! Can't wait to see it finished - do you have a targeted smallest package size ?

    Thanks for the feedback. The intention is to be able to do parts as small as 0402 resistors/caps. I've tested with 0603 resistors and believe 0402 will work just fine. The other goal is to be able to populate some leadless (QFN and DFN) packages that are as small as about 2mm x 2mm in size. The design uses two cameras -- one down-facing and the other up-facing with the ability to do fairly precise alignment before picking and before placing parts (when that level of precision is needed). I'll be testing some of this within the next two weeks or so.
