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

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 have been trying to eliminate the troublesome tubed parts in our SMT process but because we are a high mix/low-medium volume we still have to deal with it sometimes. However, the ones I can fix I'm working on. The next step in my war against tubes

So the only difference between the "regular solderers" and the BGA people is trace repair? If that is it than you should put the pay in range with your PCB repair people. We do not pay any extra for BGA rework since all they do is wick pads (common

Assuming you want to run 8 hours a day and 5 days a week, you need a sustained throughput of 2.5k components per hour. With fine pitch, futzing around, setup, etc you should really look for machines rated in the 4k to 5k per hour range. That's not sc

Hi Brandon There are at least two reasons to calculate down time on each machine. One is to know if the individual machine is having ongoing problems and either needs to be serviced or replaced. I doubt this is much of a problem for most machines.

How many operator/technician/engineer do you recommend for following SMT assembly line to achieve good uptime and smoothly running quality inspection, NPI process, tehcnical support and maintenance at the same time: - Single shift, 8 hours/day - Pri
