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

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

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

DEK wrote a paper that compared 45 degree blades vs 60 degree blades. This paper was presented at APEX 2000 by Jay Hinerman. Email me at jhingtgen@dek.com and I will ensure you get a copy.

We've actually seen best results with 60 degree blades (as measured from stencil surface to face of blade), and paste sticking has not been a problem since we switched to a higher quality metal blade. More expensive than the OEM stuff but worth it.

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

Has anybody adopted the method of stencil printing with the board at a 45 degree angle to the squeegee blade? What are the benefits and drawbacks? I've heard you get better fine pitch results. TX Mark

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
