So I found an early model samsung sm320 for under $20k BUT it needs a new motor and has 15,000 hours (not sure what life of one of these is but hardly seen a Samsung with 20,000 hours). The Juki 750 was highly recommended and its under $10k with fe

Any half meter conveyor should work for you. Any SMT equipment broker should be able to help you fine one too. Shouldn't cost more than a few thousand dollars (US) tops. Check with the seller of the package you are considering, I'd be surprised if h

Price guess is for used from a dealer. if you hunt around, or watch auctions, you can probably find something cheaper. A conveyor isn't needed, you can feed right from the printer to the P&P machine, however you will want to do some visual inspecti

Hi experts, I have some multiple and randomly missing components after reflow. PADs are seen in AOI as if the component was never there. I have seen no evidence of the chipmounters missing any components at all while populating the board. We don't ha

Normally some random components of size 0604 or below and may be due to a thermal mass being close like a transformer or AC electrolytic caps. We tried changing fan speed, but this will change the thermal profile and avoid the thermal mass from bein

Minami vacuum reflow is easy to maintain air tightness, and oxygen can be reduced to 50ppm or less by filling N2 gas. And generation of oxide film can be suppressed, and production in low oxygen environment is possible. In addition to the air tightne

A few times I have had success limiting movement in the oven by splitting up the paste apertures. In this case it might work if you had three bricks perpendicular to the leads.(maybe more) The trick would be making the gap between them big enough to

http://www.aoisystems.com/ I was at the SMTA show and saw this company's booth. It looked like a good product at a good price but it doesn't do 3D AOI. The sales person was saying that 3D AOI is only useful in cases where a lead pin is hanging in
