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

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

Dear members, Recently we have found that solder mask thickness variation could lead to solder balling under QFN packages for a high reliability device. Is there any industry proven method for solder mask thickness checking? Any equipment or any me

Hi Dave, Thank you for the input. We have completely checked the whole process and solder mask thickness is the only thing that might impact. I wonder whether you might know chemical solutions capable to dissolve solder mask? Regards, Pavel

Hi all, We plan to buy solder paste height measurement machine. However, not sure which is the better one..2D or 3D? As far as I know,3D is quite slow and but more accurate in term of measurement result. Pls share with me if anyone who has this e
