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

Boy, I step out for a bit and everybody picks on me (just joking). I believe I may have been off base a bit. Checking every bit of your stencil design is very good - I do that too. I calculate LXWXH and reduce or over print where needed, depending

| | Bernie, Steve Gregory approach is the simplest solution. But,If you ever get yourself into a real bind and need an array of holes added and the cost of a new stencil is astronomical. Approach Hamlet at BeamOn. I have seen him add and enlarge hole

Hi Steve-O, Good question(s). This process was set-up by an engineer that had a PhD in statistics, took him a year to develop and then thru it over the wall at us. The biggest problem we saw was SPC to measure solder volume. SPC is good for measu

What's important in stencil printing (which differs from screen printing) is providing a consistant volume of paste at each interconnect. The process window varies in proportion to the pitch. More than 60% of all defects are related to solder depos

Simple differences. Both processes require a very similar machine platform, controlled motion, vision fiducial recognition and alignment of a substrate (PCB or hybrid ceramic) to the "image", the image being either a stencil (hence stencil printing)
