Hi all, Can anyone explain the main difference between using a 45 degree squeegee angle over a 60. thanks in advance d

Strange? Can u explain why magnetized squeegee be a factor, not to mention rusty squeegee?

Hi, I always thought 45 deg squeegee blades were the way to go for solder printing. What are everyones opinions? Does anyone think that 45 deg blades will help prevent solder paste from sticking on the squeegee blades since equal amounts of paste

You're correct 45� is preferred. 5 Paste sticking to squeegee: * Squeegee is heavily magnetized * Some pastes stick more than ... * Plastic squeegees stick more than metal * Old metal squeegees stick more than new * Paste needs to be worke

Sure, the rolling action of the paste creates a weak magnetic field surrounding the paste. This is similar the field created by electric current flowing through a wire, as first described by James Maxwell. After creation of the magnetic flux, the m

Tony Although I agree in principle with Dean that 45 Degrees would be ideal, most of the squeegees I have worked with have been 60 Degrees to the stencil surface. This seems to work best with metal squeegees when printing HASL boards, because the sl

"45* is a common angle of attack. Squeegee blades are commonly manufactured at 60*. The combination of the angle of attack and the blade angle results in an actual printing angle between the two due to down pressure and flex of the blade." Ahhhh, so

Hi all, We're starting up tests for pin-to-paste and, well, things could be better. We're testing different pastes and we're testing different apertures rules and, well, we're still testing. It's coming close and we're getting pretty good joint

I agree with others here who have questioned the amount of solder and reliability of the joint when using this aperture shape. I have had experience with these with MELFS, and the main issue I've seen comes when cleaning the stencil - all those littl
