Can anyone suggest me if it is necessary to measure the paste thickness after contact Screen printing.Is it a very vital parameter for the production process?

I have dealt with it before and usually it's consistent, so you use some simple math to work around the issues. Now, if you have so much variability between different locations on your board for resist thickness, HASL thickness, etc., that it fouls

Yes it is vital for process control.

We have an AUREL CS1222 machine to measure the thickness of the solder paste deposited on a bare board by a stencil printer. This device has a laser beam that has to be put on the pad where you want to measure the solder paste thickness. The measure

Hi Dhanashekar, I'm with Chris on this one, unless you are carrying out 0201 or ultra fine pitch placement it's a helpful but not critical tool. We found most print errors were avoided using the 2D vision on the printer, combined with plenty of aut

I'm in a similar situation. We have a pre-historic semi-automatic printer that does a decent job, but would like to get an automatic printer. I've only just begun looking into the different options available, but would like one that could inspect t

Dhanashekar, Yes this is an important proces control tool. This will show if you printer setup is correct however, I put more importance on coverage. If your paste height is 1 mil shorter than it should be, you may need to look at your printer setup

Hi Chris, We use MPM's, where you can set the paste inspection to look at whatever you want it to (remember this does slow cycle time down) and we swear by them. However I have also met many happy DEK users who believe their machines are equally as

I am currently looking at the volume of paste being deposited on a PWB 2.4mm thick with a 0.25mm tolerance. I am looking for information on PWB variation and a MPM AP25 series printer, and can the volume of paste be controlled on varing PWB thickness
