Stencil and PCB Coplanarity measurement

What I mean is.... What Brand and Model should I buy to measure coplanarity between this 2 surfaces that could measure micrometers of difference I think that normal bubble levels are not precise enought for this use ^^

Are you doing actual measurements of the dummy parts placements? or are you just doing a visual go/no go check? If doing actual measurements, be sure to use mil inch units of measure rather than mm. Mil will give you more accurate readings. mm force

Hi Experts, I am interested in having a tool or process to measure coplanarity between the PCB pushed-up in the printing process and the Stencil. Therefore having a way to calibrate them.

Hi guys HELP!!!!!!!!!! I have been tasked with working out a chart to show calibration acCuracy and that my machines are in control I say to myself I know they are cause I have no misplacement of fine pitch but this is not good enough for my co

....and now you have the YIN and Yang of it. Of course, Dave's perspective is just as valid as mine. By the way, I prefer Hearts over Solitaire!

The easiest way to do without special tools is to use level. Check machine co-planarity on the conveyor rails in both directions(you can do that with rails down or rails up or both). Then check co-planarity on the stencil. If the level shows the sam

Of course, the more accurate the better. However, it might be a challenge to calibrate with really precise one - still better to take your time and do it right. Good luck!
