Foam fluxer maintenance, storage and cleaning

We've started off with Kester 951 'no-clean' so far which is alcohol based I believe. It seems to do very well with foaming, activation and low residue, but if we can move to water based and get good results that would be great. The 951 flux and thin

John: Three things: 1 You are correctamundo!!!! What's the difference between slopping alcohol on dirty boards and washing dirty boards? Clean boards!!!! By the time those very nice people get done with their alcohol cleaning (a nip for the boar

Hi Danial, Yes, you can use one cleaning chemistry for all paste types. There are many available chemistries from many manufacturers. The chemistries that I would recommend include: StencilWash Plus from Aqueous Technologies http://www.aqueouste

If No-Clean flux does not need to be cleaned, then why do I get readings of up to 27(ug NaCl/sq in) on boards that are not washed, up to 23.4(ug NaCl/sq in) on boards washed with DI water only and from 1.2 to 10.1(ug NaCl/sq in) on boards washed with

Casimir: Let me expand on something that I said in my response to your thread on ionic testing. Generally, no-clean people don�t use ROSE testing as part of their process control, because the ROSE test is essentially washing your board in DI/IPA �

Casimir This is not an easy subject. How did you process the test pieces? Was the flux used correctly at the required and recommended level? Did it see the wave properly? I am not an advocate of no-clean but we do have customers who coat over no-cl

Dave You are so right about that point. I still use some cost models we ran up some 5 years ago. I took one to a customer and showed them that they could make $400K more PROFIT PER YEAR running OA v No-Clean. Their response? Well, we don't believe
