We're in the high rel market and use a lot of 5 mil stencils. They give plenty of paste to meet IPC class 3 and survive over 1000 cycles of -40/+125C thermal cycle testing.

By changing paste and making a better profile, it seems like we have enough paste. The process was just not working very well with SN100. So far the 5mil looks good, so thanks for the input!

Look at the SJ Inno Tech equipment. Great machines with in-built 2D or 3D SPI. I have 5 printers under my control, first machine was installed in June 2008 - and I haven't any headache with it.

If you failed math like I did. A 0.005 inch stencil would work fine for those parts. Most stencils are 0.004in for fine pitch 1005s 201s. 0.005in is probably the most common generic stencil. 0.006in generally is if you need extra solder for big parts

A few years ago a lot of stencils were 6 mill and 7 mills and a lot of people still use them. these days with such a hi mix on the boards 5 mill seems to be a good compromise. if the 6 mills is working for you that's fine. One thing to note as you go

Thanks very much everyone. > > I'll try out a > 5mil and see how that goes. If you are using 6mil stencil and you are saying that you need more on the 0603 parts then you might want to look at your squeege pressure. What kind of squeege blades ar

I worked on MicroFlex. All axis move via electric motor drive. Carraige reapatability is +/- 0.0005" (12 micron). Cameras position more easily on linear bearings than the swivel type. The alignment accuracy and repeatability easily supports sub-20mil

= 0.66 aperture opening to the stencil wall has been shown to provide the best transfer efficiency and repeatability of the deposited paste. Values from 0.66 to 0.8 insure a good paste release from the stencil. The biggest impact on area ratio is the
