What is TTW soldering

Electronics Forum | Tue Nov 30 13:58:57 EST 2010 | flipit

Reading some spec sheets and am seeing profiles for reflow and TTW soldering. A Google search tells me that TTW means "through the wave". Am seeing this acronym on LEDs mostly. I have never seen this acronym before. Why not just wave or reflow so

What is the issue?

ASM machines have great algorithms for BGA and I am positive it will detect missing ball. Still, on your pictures it seems like you are severely starving solder in the locations shown on X-ray. Part seem too small to bend that much in reflow to form

What I'm seeing is an occasional pattern of tear drop shaped features in a sea of nice shiny solder. The little islands don't really have any relief.....it's more of a surface finish feature than a 3-dimensional feature. The wetting angles are good,

how clean is clean?
