Did you use the frame grabber software that is available for the LSM? I used one in the past and we also failed the GR&R we then installed this software and it became very consistant unfortubately I cannot remember who sells this software. Anyway,

1.67 always on the sample boards measured. This is very fast and pretty good measurement for a paste dispense control. Boards do not stand out-side for long times. Inspect the height for critical components only, in the initial stages. Once your Cpk

Like other things, the more you pay, the better the gage. I'm not sure which Cyberoptics unit you're considering, but LSM has a lousy gage [R&R ~25%]. We use a microscope with lousy gage that costs waaay less than some laser guided thing. Search t

Ok Guys, I really appreciate your answers. we are using the LSM 300, so I'm going to check about the software you mention in order to check if this could help.If you have any other idea, please let me know. By the way, I didn't think that somebody w

Juan, I believe in term of height vs volume, volume is much better control. By the way we used Cyber Sentry 2000 which allows us to measure volume, height and area. My plant normal practice is measuring the height. Last time I did the control limit

I agree with chuck, but would like to add. 2D is a great option and helps to keep your printing process in check, it will measure the x & y coverage on the pad. It will help you determin when your stencil aps become clogged or when the bottom of your

Are you using HASL PCB's? Try measuring a bare board and compare.

When you measure "solder paste heigth of 7 & 8 mils using a 5.0 mils stencil," are you measuring the top of a flat brick? Sometimes if you snap-off the stencil too fast, the paste touching the stencil walls form peaks along the edge of the brick that

Hi Jorge, Take a bare board and measure over the same pad. We have had similar issues with a higher deposition than the stencil thickness. In some cases, we have found that the top of the pad was higher than the solder mask. Our inspector uses the b
