The general experience of Alpha technical support experts is that 10-20% of all printing squeegees are used longer than advisable and therefore are used when worn out. That means that the printing results and the soldering quality will be affected negatively. In the offering of Alpha squeegee blades are available that are more robust than usual and give smooth prints through their long lifetimes. When thinking about the printing process besides the machine dependent factors like board support always consider that good quality squeegees with an optimised design stencil can save You a lot of headaches.
