Hi Steve Thanks for coming back to me, you are correct IPC class 3 is required. We are getting great wetting onto the device but not as per IPC 3 with the wetting rising about 0.25mm. I am questioning whether it is actually possible with such a (re

For those of you out there, like myself who are still using 2-d to measure paste ht, I have 2 questions. 1. Typically, what tolerance are you applying to your ht? +- 1 mil, or what? 2. Are you using metal squeegees, and if so, have you found that squ

Does any one know how to calculate BGA height change after reflow oven? I guess the calculation will be based on the component size, weight, ball diameter and ball count of the BGA, but how to get the actual height?

I'm new to SMT. Now, i'm making program for SPI machine to inscpect for solder paste of SP60-MU. I think this is a very good printer but some times, my program shows only 50-60% of volume transfer; and the average height is very high: nearly 200 pct.

Can paste height be measured by IR rays instead of Laser rays. Any tool available.

Is that accurate? If so, what are your aspect & area ratios? [Similar to the JerryS comment above.] * You say, � � and the average height is very high: nearly 200 pct.� => Our troop can make paste that height too. They snap the stencil-off a fast as

Dial indicator on a post/base. You might need a fine point tip to get between adjascent components and the BGA. Or... if you're real fance schmancy you could use a CMM if you have one.
