Hi, anyone know when Universal stopped making & supporting stand alone sequencers? We don't have the space for a 120 module 6241F or similar. Thanks, Rob.

I worked with Axial-5 and Radial-5 machines and there are no alone sequencers.

Hi Alexey, I've used Combi machines too, but Universal were still selling new 2596D sequencers in 2003, way after the 6241D,E & F: http://www3.uic.com/wcms/Images.nsf/(GraphicLib)/366-00B.pdf/$File/366-00B.pdf

I know that OA is water soluable. But what exactly does the acronym "OA" stand for? "Organic something-or-other". I've checked the archive and can only find reference to oa, not what it actually stands for. thanks, spanky

I will second the previous answer that it stands for Organic Acid. "Acid" being the key word as to why it must be thoroughly cleaned.

OA stands for Organic Activated. In the good old fo SMT processes, a lot of different fluxes are being considered. RA, RMA, OA, etc. If you look at the present no-clean paste, it is actually RMA.

Could you provide the specific alloy info (percentage od each) OR provide the melting point of this alloy? Please also provide the component specs (pitch, ball diam.) And the pad size and design used on the board. Russ
