Dear Leeg, Generally the faster your print speed the more down pressure you need on the blade to roll the paste and wipe the stencil surface clean. Pastes with higher viscosity need more pressure at slow and high print speeds. Too much pressure cause

Here are some: Printing Speed : 2.5 ips (inch per sec) Stencil Thickness: 10 - 12 mil but the latter is the best. Dots sizes: u can get that from the Forum Archive...I used Dave F's dot sizes recommendation...they are good! Squeegee Blade : use met

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

| Anyone knows what is the optimum squeegee angle for screen printers. | | 45 Degrees. The forward velocity creates a downward pressure equal to the vector pressure (equalibrium). This is commonly known as paste "rolling action". Too obtuse an an

You'll struggle to find low end machines that accurately and reliably place 0201's (despite some of the manufacturers claims). You'll also obviously need to place the larger components on the same platform, accurately which will really cost you.

Hello Since we have a few years experience with these printers we might be able to help. Is these problems always with the same components? Is this a new type of paste for you? Is there tape on the bottom of the stencil? And how much pressure do

So, if 45� is theoretically optimal for aperture fill, but 60� is better for defining fine pitch bricks, is 52.5� the best compromise for an all around design, or does it not work that way? I see blades with either one angle or the other but with th

Oh sh*t, we have the same "problem". But it's not really a problem. Depending on how thick your stencil is, and at what speed you run your squeegee blades at, you will get this deflection of the stencil. Age of the stencil is also a factor. You c

That's my main concern, the patchy/splotchy appearance doesn't look as pretty, especially under a microscope. When it was mentioned that my oven may be too hot in the ramp-to-faux-soak it was the first thing I tried adjusting. As far as our blade pre
