If you require several changeovers per shift the quick connect closed loop pump option would be your best bet.You can change between pump and blades within minutes. Hoever if you have several different size pumps a simple pump switch over would be pe

You want to use a rubber squeegee with as high as a durometer as you can get away with, order two or three sets of blades starting with the softest and then progress up the the hardest, the reasoning behind this is the softer squeegees will wear out

Here are some: Printing Speed : 2.5 ips (inch per sec) Stencil Thickness: 10 - 12 mil but the latter is the best. Dots sizes: u can get that from the Forum Archive...I used Dave F's dot sizes recommendation...they are good! Squeegee Blade : use met

Total Force is the weight on the squeegee blades. Generally you should set this by the length of blade you use. A 12 sgeegee blade would require a Total Force setting of 12 pounds. So, if you have 8 inch long squeegees, you should be OK. Your b

We're in the high reliability market and build to IPC Class 3 standards. I honestly don't know much about ESD but our in-house expert measured an 8kV charge on the board after printing with a plastic stencil and rubber squeegees. He wasn't too plea
