Hi, Check to make sure your paste is not dried up, and it should roll across the stencil, not slide. Also, if your running in a cold environment, then that can stiffen up the paste, and it will still to the blades, and not roll over the stencil corr

no there is lot of difference between both the alloys.. SN100C works better than SAC305... gives little more time to remove and replace the unit without completely loosing the Cu... but there are customers who still prefer sticking to SAC305... so th
