Is it possible to have a no-clean flux that could be removed with water. I would like to use a single flux at wave solder that could satisfy both no-clean and water soluble customers, within a contract manufacturing environment. Thanks, Tim A.

Chemistries are limited for WS Mask. Try looking/changing other components, trying different flux types is easy, identify water cleanliness, is it ionic/no-ionic...probably is benign. Could be a plating reaction which is tough to investigate. Call

Have been playing with VOC free water based fluxes, so far they appear to come clean in an aqueous cleaner, I went to perform Ionagraph testing but our machine was down so I will let you know if they pass ionics.

Change pastes, although insufficient heating may leave excessive residues. Is this on one board or all products? No Clean or water soluble? Do you profile accurately or "guesstimate" your settings?

All things are possible Grasshopper. You have two choices: 1 Some no-cleans are cleanable. Talk to your sales rep. 2 Rosin based fluxes are cleaned in hi-rel aps, but not cleaned in many less than hi-rel aps. Be aware that in both instances, you

I agree but, are there really heavy metals in this water? Our process is as follows. Print Paste Reflow Board (no components, water soluble paste only) Wash Board Same reflow profile for almost every order so no solder balling issues etc. Carbon an

No-clean is definitely a cheaper process. It will eliminte cleaning. Some issues associated with no-clean are: -- the flux stain left behind on the PCB will create a cosmetic issue. You may want to seek advice from your customers. -- next, the flux

We are purchasing an ultrasonic cleaner to clean pcb asseblies that have been produced with water soluble flux based solder. After cleaning a batch of assemblies, the water in the cleaner will need to be disposed of. My question is: Do we need to

Hello Greg, there are several things to be considered: I will start this investigation in the oven. Look in your cooling zones. Many ovens build up a lot of flux there(especially the ones with water cooling) and should be cleaned every so often.
