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

Cleaning no-clean is the pitts. If cleaning required migrate to water soluble. Can IPC help here? No cleans only need to be removed per IPC if the joint inspection is inhibited...and in general if form-fit-funciton is not achievable. But then th

I recently finished analysis of no-clean fluxes and Ionic contamination and cleaning processes. The results were eye opening. Summary: If you clean a no-clean you better do a good job. Many no-cleans produce a "waxy binder" to encapsulate the tro

Really, if you start out from the beginning planning to clean the boards, then DON'T use the no-clean flux! The way that stuff is made, it leaves a hard, low-solubility residue that takes a LOT of effort to get clean. If you plan to clean, use a wa

I am going to open the flood gates of comments. The purpose of no clean is so you do not have to clean it. Yes I am aware of no cleans that you can clean. If you need to clean the boards use a water soluble paste. If you do not clean, no clean prop

150º de-ionized water, however, if you're doing hobby work at home, regular hot water will be fine. Just be sure to allow the water to dry sufficiently before powering up the board. You can also use IPA or a custom flux cleaning solvent available o
