Most glue suppliers recommend chemicals and methods for removing the product from stencils. What does yours suggest?

Further, search the fine SMTnet Archives for background discussion.

What I am really after is what is recommended to clean the paste from the stencil. What works best? What is really used in common practice?

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 the archives for "cleaning solvent"

Most metal stencils today are cleaned with a water based cleaning solution. 3 choices are most typical: (1) Water only for water-soluble paste (2) Water + Organic for rosin and no-clean (low residues. This affords lower temperatures and is easier to dispose. (3) Water + Alkaline Saponifier for rosin and no-clean (low residues). This affords greater aggressiveness on harder to clean "no-cleans" and needs to be rinsed thoroughly. This can be harder to dispose.

All of these choices are compatible with spray in air systems.

Hope this helps,
