| I would like to hear from anyone producing high mix (~200 modules) with low volumes (5-2000 per year) using an automatic line running lot sizes in the 5-50 range. We are engaged in an investigation to invest in this capability. A view into the or

It depends on your application. Are you going for high volume low mix, or low mix high volume? What is your expense budget? What are your factory space requirements? I have worked with Fuji, Siemens, Universal, Panasonic, and Mydata. My pref

Maybe we should better define the type of line and the expected utlization? Are you a contract mfg. or is this your own product line? Are you hi/low mix - hi/low volume? I have a hi-mix/low volume Siemens line (S23/F5) that I am able to get 40-60% u

Low air flow huh. This is interesting, I have a low end machine that has adjustable air flow and I was having some shorting problems awhile back (corners mostly) and my first attempt was to preheat the board up to 170C and then use lower temp to put

72 different part numbers, 53 being 8mm, remainder being 12-44mm and 3 tray. It may be low but anymore than 100 and you give up throughput because of feeder locations. And thinking about it, 70-90 is low for a low volume high mix line. I guess if I w

It all depends on what type of board you need to solder. If your boards are small in size and low thermal mass and your conveyor speed requirments are normal, then I'd say the OmniFlo 7 will do the job. It has a max zone temp setting of 280C. The cur

Comments are: * Sounds like it's necessary to clean "heareous F381, F352 no clean solder paste" in your application. Consider a paste that may be better suited to your application. * If you're cleaning "low residue flux", consider using an organic ac

Hi Piet, We looked into this too at some length (we do a lot of FPGA and 16 & 32 bit micro designs) and every semi auto machine we checked out was to be fair, crap. Especially on the number & type of devices you could sucessfully handle, set up & a

TAL Too Long - dull solder joints, dewetting. TAL Too Short - cold solder, insufficient wetting. You want TAL to be as short as possible (but not lower than 30 seconds), but long enough for every solder joint to be above TAL for at least 30 seconds.
