Hello Ok there is not much info here. What you have to mae sure of is several key factors. 1. Have you entered the correct stencil thickness. 2. Are you using the stencil gerber (not the paste layer) The paste layer is usually not adjusted for ap

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.

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

Hi All. I want to know what is the IPC/JEDEC standard for solder paste printing defects. From the brochures of SPI Machines, the recognized defects are excessive, insufficient, misalignment, no solder, bridging, and solder shape error. What document

There is no such standard, nor should there be. The important thing is to make good solder connections. That's IPC standardization focus, defining good results of manufacturing process. The approach that you take in developing the process of making g
