Dear All, I'm looking for the complete SMT equiment line (solder printer, P&P, Reflow) uses for the small volume production line. I happen to know that Manncorp and APSGold can provide the complete ST line, but I haven't hear and use these machine be

TBH I think perhaps the OP deserved it, there is perfectly good explanation of Reflow and Process Window Index on Wikipedia for starters and if you want more all sorts of FREE specialist papers on things like reflowing flex circuit, lead/lead free et

| I have a severe problem with flux residue being drawn up the vent ducts of my reflow oven. This residue reaches a critical mass then begins to flow down the ducts and becomes very messy. I run a no-clean process and use IR oven. Has anyone else o

You did not tell us where your boards fit on the thermal mass range. That is key. I've run Pb Free low to medium thermal mass boards with good results on a 5 zone oven (5 top/5 bottom). You should not have a problem running a medium thermal mass boa
