I am curious as to why you need to mix.... We use a 500g cartridge with air gun. Our process is remove the cartridge from the fridge, allow it to warm up to room temperature before inserting into air gun, then apply bead of paste to the stencil. N

Here is some thing that I wrote a while back on solder beading. First what is a Solder Bead? The term solder bead is used to differentiate it from solder balls. A solder bead is a solder ball but its location is normally constant unlike solder bal

I'am having a problem with 0805 component where right after placement, the component tend to move from the pad. I'am using 'horse shoe' aperture for 0805 component to resolve the solder beading issue. Does this 'horse shoe' contributing the skew/shif

Successful solder paste overprint is a function of the solder paste rheology, solder mask and through hole component stand off. * Solder mask with a high surface energy will permit a larger overprint than a solder mask with a lower surface energy. In

Ramon, I have had experience in the problems you are witnessing. The problem can relate to a number of factors. Obviously the printing process is the first place to start your investigations, try looking at the stencil apertures for bleed under the

I have observed solder balling for all aperture sizes tested. Solder balling levels appear to be better correlated against the amount of solder paste that is underneath the 0201 component terminations after placement rather than comparing this to th

Similarly, we have eliminated solder balls by using an aqueous washer.

We do not understand the question. Take a deep breath, remember not all of us are trained as geologists. The smallest solder ball we've seen is a little less than 5 nm.

Awwww, man. I was looking for something a little less on the anecdotal side for our local municipality's environmental stewards.
