| Does anyone have any recommendations on spray fluxers? Are there major differences between the high priced ultrasonic machines to the low priced flux/air spraying machines? We are going to be spraying an OA flux with 11% solids content. Are there a

If the flux is already eating thru Cu it must have been some time since the boards were soldered with the OA flux. Ionic contamination testing (with OmegaMeter or IonoGraph)can be done to find contaminated boards and cleaning the boards can be done

Typical conveyor speeds on leaded alloys and OA flux is 2 FPM. Typical conveyor speeds on lead-free alloys and OS flux is 0.5 FPM. Temperature should be 140 F. Most polypropylene inlines cleaners should not exceed 140 F. -Mike Konrad Aqueous Technol

I am looking for data / info on how flux may contaminate the solder in a Wave. I have a customer who requires a no clean process. Our wave is equipped with 2 separate fluxing systems and I would like to use OA in one and the No Clean in the other. Th

| Very shortly I will be evaluating OA flux and aqueous cleaning to replace our RMA and solvent cleaning process. I am primarily interested in batch aqueous cleaners for reasons of budget, floor space, etc. I am concerned about the ability of H2O t

Hey Dreamy, Dave is correct. If you attempt to clean your water soluble (OA) flux with water only, you will turn the no-clean flux white. No inspector or end-user will accept this. If a proper cleaning system is not available to you, then I would

All Y'll How do you clean components that must be added to an assembled board after water wash? BACKGROUND Our basic process goes like this: 1 Print paste with OA flux, place, reflow, wash 2 Repeat 1 3 Insert PTH, OA flux, wave, wash 4 Insert
