Also I suggest you read through the Charity Report I produced on the specifi process of Double Sided Reflow Assembly which you can also get from the SMTA. All the money from the sale of the report goes to the Charles Hutchins Scholarship Fund which T

SMTRESEARCH.COM OR WPSALES are also options. There are lots of them out there who will supply just the discs, new nozzles, or do retips on your nozzles (cheaper) and all I've dealt with are cheaper than Fuji. As Kevin says your disc's need to be cons

I have found that if you have a custom carrier with support between pcbs on both SMT reflows (If you palletize) it will eliminate warping. Also Prebaking PCBS with wieght on the top of them helps too. Also look at the cooldown of your oven profile, y

dgrenier is on the right track. We are a volume shop and with a up back stencil you can keep CFM line going with no down time. DMPO also at our shop have inproved. We also use AOI equipemnt as a process indicator to monitor when stenicls need to be c

If your pad designs don't meet IPC recommendations, using home plate may have adversely affected the (possibly marginal) placement tolerances. This could also be caused by an incorrect home plate design, which IPC has also given recommendations for,

Interesting concept. Are the PCB's still coming off of the SM line one at a time, or are they being batched? It also seems as though you would need more duplicate tools since most stations are tool specific. It does make sense though because whether
