I need some feedback on aqueous cleaners. We currently use a Unit Design batch cleaner. We will be looking to upgrade our board washing process and batch sizes in the near future. I am looking for user info. on the advantages/disadvantages to using b

Hi Rick, Cleaning No Cleans is becoming more of a norm. It is true that changing to a OA flux/paste would be a easier process to control from a cleaning standpoint. A water soluble process will cost a great deal less as well. However, if your pro

Tim, try and incorporate an inline wash system. We use one with a surfactant and it cleans the "NO CLEAN" fluxes well. If you dont have an inline system, you can manual clean the boards with an surfactant and IPA. You can also do an ionic contamin

From part documentation: CLEANING INSTRUCTIONS A no clean solder system is recommended for IHLP's. If cleaning must be performed, an Isopropyl alcohol is recommended. If de-ionized Water Wash is used insure it is followed by a thorough warm air dry c

If the batch cleaner is truly closed loop, then 100% of all of the process fluid (water) is captured, filtered (particulate, carbon, resin) and reused. This answer is based on a traditional closed-loop batch cleaning system with an integrated water

Dear Dreamsniper, A big hidden cost in any cleaning system is the cost of diminished production and rework. I assume you are cleaning the adhesive stencils manually since there is no equipment cost in your formula. Manual cleaning of adhesive sten

Hello JB, Based on the double sided assemblies, the misprint cleaning process can demand the cleaning system to remove both raw solder paste from the misprinted side of the board, and, reflowed flux residues from the assembled side. Recognizing and

Hi Wade As Steve says - are you sure that the lead is in solution? Particulate lead like solder balls is much easier to remove. The answers are going to depend on total output in gallons, maximum flow required and what has to be removed. If you're

There are a few good de-fluxing chemicals and many more �not-so-good� de-fluxing chemicals. As a manufacturer of cleaning equipment, it is imperative that our customers use a de-fluxing chemical that: #1: Removes flux #2: Is environmentally safe

Hi all I have a question about DI water for cleaning system. What water quality should ionic exchanger produce for assembly cleaning (SMD and THT components with BGA and microwave application). What is recommend water conduction and minimal level (0.
