Hi, Thanks for the info. How clean can wave soldering get? We are looking at a carrier that masks off most of the board when we run it through the wave, so hopefully this works. Regards, Grant Blackmagic Design

Hi, Guys, Can anybody tell me what kind of reflow profile is best for a no clean solder paste: Ramp-Soak-Spike or Ramp-to Spike? The paste we are using is AIM 293DX2B. Thanks a lot.
