We manufacturer cleaning equipment (full disclosure) so, our answer may seem self-serving. The facts however are accurate and relevant so here I go� Changing from an OA (water soluble) flux to a no-clean flux makes sense. After all, even die-hard

Batch vs. In-Line for straight aqueous cleaning applications tends to be all about production. You'll have to see what cycle times you get from the various batch systems out there vs. the in-lines. In-Lines come in various sizes. Some of the leading

Cleaning RMA fluxes simply requires selecting a washing chemistry (either Solvent, Semi-aqueous or Aqueous) and an appropriate cleaning sytem. Your lot size would be easily handled with a batch system. visit http://www.aat-corp.com/Technical/Def

Additionally, increases in temperature can increase the water's rate of reaction with the flux. Sometimes, only a 5 degree change can make the cleaning difference. If the flux inconsistently presents itself, then the likely cause is something in

Because the HASL process most deal with bare metals, HASL flux residues are generally more active than solder paste residues. Typically a Rosin Active (RA) flux is used in the HASL process. These flux residues should be removed from the bare board

Hi John, A primary consideration is the type of flux you are using. If it's water soluble (organic acid) then cleaning is highly recommended. Any other flux that fails the copper mirror test, we'd strongly recommend cleaning. Passing the copper m

Thanks for providing the pictures. We evaluated what we could see and have the following idea's. 1) Because of different thermal charatoristics between the topline and your product, your Motorola BGA solder joints may have experienced a higher refl

There are several manufacturers of batch-format de-fluxing systems. Here is a list of them: Aqueous Technologies http://www.aqueoustech.com (909) 944-7771 Batch and Inline UnitDesign http://www.unitdesign.com (714) 672-9944 Batch Austin American T

First, I should state that my company manufacturers batch and inline de-fluxing systems. Because we manufacture both formats, we remain unbiased. In fact, it is in our best interest to recommend inline cleaners since they sell for considerably more

Hi Sandy B, You certainly can clean the BGA's using an inline or batch process. The correct method to hold them during this process, is the method that provides the desired outcome. I'm familiar with the desired outcome for cleaning singulated BGA
