from my experience, no clean mean "difficult and cannot clean" Normally, you will observe white residue when cleaning it. You should study the flux in the no-clean solder cream before cleaning it. Or change no clean solder to clean type solder

You need to use speial cleaning solution to clean the residues from no clean pastes. Alpha has a solution,(I think Alpha 2010)that can clean no-clean residues. Zestron is another company which specializes in cleaning no clean residues. contact Alpha

we are using heareous F381, F352 no clean solder paste. specially in qfp for high frequency board we observe that cleaing / removing of ' no clean flux 'is require. if we do not clean same most of time after all test & envioumental test it shows pin

Water will not remove no clean flux residues because they are not water soluble. Solder paste with no clean flux should only be used when the assemblies do not need to be cleaned. That said, you can buy special cleaning solvents specifically for re

When switching from cleaning RMA to a no-clean flux, one area that is commonly overlooked is the stencil cleaning operation. Stencil cleaners that are effective in cleaning RMA often fail when cleaning no-clean (especially alcohol cleaners). Pallet

We recently got a batch wash machine that can use a chemical cleaner. (not a saponifier). NOW I feel confident cleaning no clean boards. Without a machine that can heat water and use a proper cleaning agent, I would not trust cleaning no clean boards

Does anyone know of a reason, other than visual, contact, or testability, for cleaning a no-clean residue off a board? Are there any SIR or long term reliability advantages to cleaning a no-clean residue?

Here are some cleaning chemistry companies that have products to clean no-clean flux residues: www.zestron.com www.kyzen.com www.petroferm.com They all have engineers on staff that can assist with setting up a custom cleaning process.

definitely don't mix clean and No clean. Run No Clean as you decided, but have your flux and paste manufacturers advice, how this flux can be cleaned(if you decide or required to clean). I know for a fact that some of these NC flux residues are almos

We have been populating lot of BGA boards and for all these boards we have been using No clean solderpaste. We are under the impression that aqueous cleaning is not recommended for BGA boards as the residue cannot be cleaned properly. However we are
