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.

No-clean flux residues can be either cleanable or not cleanable. The not cleanable type leave a milky white residue on the solder connection after suitable soaking in water. Your flux supplier will have suggestions on the appropriate flux.

I agree, the flux will probably burn off before it gets to do its job. Def not a good idea....

X-RAY, X-RAY and X-RAY.. to optimize your reflow process when using BGA's you have to use your reflow profile hand to hand with your x-ray process.

??? Two assemblies assembled under the same conditions with identical x-ray results can have dramatically different life expectencies. Operating environments will have a direct affect on the product ie. hunidity, temperature swing, temp. duration, v

Hey, this is something that I've looked at and published a paper on back in 2003 at Apex, actually pert of one, the other part was lookign at how effective X-ray systems (lamanography systems) were at detecting & measuring BGA void size accuratly (co

For reflow, low soak time and low peak temperatures will help reduce the number of components skewing Search the fine SMTnet Archives. For instance: http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=6071&mc=15

Thank's Pete, I know is an old product but I would know its reflow thermal profile because I'm not sure about it. It's a linear melting or an melting with soak zone ? I haven't data on alphametals.com ...
