Steve, The 4 things I would do, and in this order: 1. Clean your stencil with stencil cleaner wipes after it comes out of the stencil cleaner. I like MicroCare ProClean (MCC-PROWR). I will even saturate the wipe with a bit of isopropal just till

Stop!!! Whoa!!! Time-aut You have equipment like "Siemens 80S & 80F, Sanyo TCM 3000 and GSM" and you're not going to convince people to clean the ever lovin' bejuice out of your stencils? You're thinking handy-wipes are going to get it done? Wha

Hmmm.... When I clean my stencils after I run a job, it is to clean the paste off the stencil so it doesn't dry out in the apertures and on the stencil surface while it is being stored. Wiping the stencils during production is to clear the paste of

So, why can't you clean misprints on Entek boards? Entek: Cheap, flat, OK shelf life, not without process and fabrication issues. Your Entek organic solderability protection is probably Entek Plus [CU106A] made by Ethone OMI. Consider getting a co

Sr. Tech, Just think about it. How do you clean your stencil after you finish the job? Dry wipe and put it on the shelf? Dry wipe will work to some extent for simple boards, but your stencil will never be perfectly clean like if you use solvent. You

I would not call them rags but would call them lint free wipes. They are 100% cotton twill wipes. That means they won't leave a residue even when wiping thruhole components, you would think they would tear but they don't. Most high quality jeans are

800 degrees? Ouch! I find that every company that I do training for has at least one person that likes to go through one tip a day. The solution is tip tinning. Tell your operators to wipe the tip on a damp sponge often. Do not buy your sponges

Russ makes good points. Your printer supplier can give good advice on machine setup also. We know we're printing well when: * Paste at least as big in diameter as your thumb is rolling across the stencil * Paste is filling the apertures * Squeegee
