We want to transition into metal squeegees. What are the considerations during this transition?

The obvious is size. Besides that, it depends on your screen printer. Some "smart heads" need to be retaught with the metal blades for each board. Some need to have the set-up programmed changed too. Angle of attack is something to double check as well.

If a rubber squeege is bumped on the edge, no biggee. But you have to be carefull the metal ones don't get dinged. All it takes is a little extra care but if your operators are used to handling the rubber one they might not increase the amount of care handling them.

in addition, your prints may have a larger volume from the reduction of scooping from the rubber blades.

Stephen reminded me of another issue - be careful when handling or wiping new metal blades. They can cut you (oh the pain).

Holders and blades can be spendy. "JNJ" is good place to get aftermarket stuff (I have no affiliation with them). I've also found laser cut metal blades work fairly good and are cheap. Your stencil supplier might be able to cut them for you if you have a drawing for them. JNJ sells blades that have a plating on them. They work a lot better than laser cut stainless blades but are much more costly (cost ratio is about 1:10 for us). You'll want to have new blades installed periodically on a maintenance schedule as they will get sort of a rainbow/bowed effect going after a while. Try to use blades that closely match the width of the print job to minimize this effect.

Hi, Thanks for the answers.

I have a few others:

How often you replace metal squeegees? Do they shorten the life of the stencil?
