I have always gone with blade length equal to board width plus 2 inches - 1 inch either side. Is there any technical reason that I could not use a longer blade, say 2.5 inches on either side?

When you increase the blade length you have to use much solder paste. As a result, we will dry-out extra quantity of solder paste. If it's not a problem then you can use longer blades, just change/adjust the process parameters.

Important mainly for consistency of pressure across the entire board length... But also quite abusive of stencils to use longer blades. Especially since (most people) when using the longer blades will bump the pressure up even higher to minimise th

Yes, it is important to ensure blade pressure over stencil is uniformly distributed across the entire length of blade. Such is possible only if the stencil is firmly supported from below, which during printing is done by the presence of the PCB itsel

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
