SPOT (Solder Paste On Thru-Hole)

Planning to evaluate the above process... Can anyone can give me some tips/infos on the above.... e.g. stencil aperture design, aperture ratio, common problems and solutions they encountered on the above process, is the profile different from an ordinary SMT process....etc...

All suggestions are welcome.

How to search the archive in this forum for the above topic...

thanks and regards,

Depending on your entry you might get a lot of entries and it�s sometimes to search through all of them but now it�s my first step before asking the forum. I think there was already something about your topic so maybe you try.

Also, not having success with holes in boards over .093" thick.
