Cycle time is one thing, "operating factor" is another. Set-up and tear-down should be seperate from cycle time as well.

orientation is also a factor here, So what is the pitch of these connectors? the lead length? the hole dimensions? surface finish? and what type of wave and flux are you running? Shorts are pretty easy to eliminate if everything is of adequate des

Hi Jack, I've seen around 7 degrees diff in max temp. The real factor here is time to reach peak and time at peak.

Has anyone experienced deformed balls on BGAs - especially very low volume build to order devices? I'm looking into a possible hidden pillow defect and think I have eliminated most of the other factors I believe could cause it. Cheers, Rob.

No kidding...and if you can guarantee the prostitution rate would increase by a factor of 10% instead of 2%......more equipment brokers would attend.

What pitch IC? Perhaps a nickel stencil will work. Are your board FR4? Warping the board could play a major factor in solder shorting.

High mix low volume I would say Mydata would be a good choice, If set up time isn't a big factor I would choose Siemens F4 for reliably, serviceability and OEM support.

Hi Roy, Depends onmany factors. Your plants environment, the ype of paste, the size of the syringe, your smallest aperture you want to release too, type of screen printer, etc... Your best bet is to perform a DOE and see for yourself.

Thank you! And I agree with you. The temperature is an important factor. I will check our supplier's control system.
