We are currently in a Clean solder process (SMT+Wave Solder+Washing). Now our management is planning to convert to a No-Clean process in SMT due to limitations of solder availability and reduction of washing process. Question1: Is it possible to was

We are re-thinking our clean vs no clean asembly process' and would like some information from users of both process'. Currently, we use no-clean, but our assemblies display residue and other contaminates and this raises questions at our customer si

I agree with Rob. Why use NC if the board is going to be cleaned anyway? Water soluable is much easier to get off if the board needs to be cleaned. Why else would they call it "no-clean"? Steve

See Daves Answer above and change it to "paste mfgr." Also most all of the cleaning companies have chemistries. Are you cleaning noclean or W.S.? IPA works if you clean them manually, Or the chemicals that the Ultra sonics mfgrs recommend. Search

my 2 cents here --- Even though the boards need not be cleaned after SMT when using no clean flux, you will still have to clean them before conformal coating.....and most solvents used to clean boards before coating will take out the no clean flux re

Your product may not no-clean compatible. "No Clean" must not be confused with "no need to clean". Your end application, operating environment and circuit operation (form-for-function) will dictate your cleaning requirements.

Remember, even if you are successful in your justification of not cleaning your final product, there will always be a need for cleaning. Screens, stencils, misprinted PCBs, wave solder pallets, squeegees, tooling, etc. New cleaning applications can

Hi Dave, No-clean paste is more difficult to remove in post-reflow cleaning applications. In stencil, misprint and tool cleaning applications however, no-clean paste poses no extra degree of cleaning difficulty. There are few special requirement
