I am trying to teach a class and the question came up about loss of metalization of the Earth pad on a chip filter. This pad is on the side of the component. I can not find a IPC call out for this type of side termination other than 3 or 5 sided 9.1.

I have a project to evaluate solderability of various metals or plated finish. I'd like to tap in to get some advise. The project is to evaluate solderability of various metals or plated finishes for RF shield application with reflow. Due to the hig

Have you considered a different solderpaste ? A different flux chemistry may help. The metals content wouldn't have to change. Just go after a slightly more aggressive flux.

Hi. I am familiar with the Transition blades. Normally, when there is metal to metal contact, as in the squeegee-stencil situation, there will be scratches, or a "brush pattern". Sometimes it takes the pattern of the high profile surface elements u

It depends on how much paste you put on the pads. Assuming your stencil is 1:1 to the pad and the solderability protection on the board is something other than HASL, we'd guess that your solder height is approximately 50% of your stencil thickness,

Some of you smart people might have seen this already. Although, since I don't live in Siberia I don't think I have to worry about it much either. http://technology.newscientist.com/article/dn14175-jekyll-and-hyde-metals-crumbling-trick-caught-on-fil

You've posed a very broad question, I'm not sure what you're asking. As a starting point ... Kester reported “The Effect Of Metallic Impurities On The Wetting Properties Of Solder“ [http://www.smtnet.com/library/index.cfm?fuseaction=view_article&art
