Hi Bill, Gasketing between the board and stencil may leak alittle, giving you a fuzzy print. If not, you should be OK. Another variable may be you need to perform an understencil wipe more often, adding to your cycle time. So why ya wanna double

The biggest problem with double printing is that if the squeegee pressure and speed are correct, the stencil apertures are already filled with paste. Printing again can force paste between the bottom of the stencil and the top of the board creating

If you MUST double print, probably to get good aperture fill near board edges, I would recommend letting off on pressure (maybe 20%) to minimize the bleed. Alot depends on your board (gasket) quality.

WHERE DO WE LOSE MOST COMPONENTS? MACHINE? OR DURING SETUP (INTO FEEDERS)? IS IT POSSIBLE TO REDUCE MACHINE ATTRITION(THROWOUT)FOR SMALLER COMPONENTS SUCH AS 0402'S AND 0603'S? THE MACHINES INVOLVED ARE MSR'S AND MV2F'S(PANASERT).

I'm using an MCS30 controller and started running the scan disk two days ago and it's still not finished, anyone have any idea on how long it should take or what could be wrong with it? Any help would be appreciated, Best Regards ~Nick

Every time I had a disk utility take that long, the hard drive was pretty much not usable. Could be write errors or bad sectors on the drive.

Yes, but you can expect a 20%+ pickup failure rate. Chuck-based alignment was so 1990's.... :)

Pls advise me how to calculation of smt cost / shot, key performance point of smt production.

Cost per placement = [Equipment cost/5 years/components placed per year] + [Working capital/ components placed per year] + [Expenses/components placed per year]
