I have a customer who runs A-D applications with 5GHz analog and it is 100% no clean. The only answer that will be acceptable is what works for your circuit design.

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

Dear Ing, Have you analyzed why some RF device aren't operational after washing? An assumption is that failures are related to the ultrasonic energy applied. Other possibilities are for poor rinsing, poor drying, inadequate washing on those failed

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 �

Graham STOP!!! You can not be totally serious. A five year old cost model counts bean, and beans are beans. I have to know more about the calculation. If this bores some of your gear-heads, click on "return." � Help me with the terms: - "Ops cos

Well first off I wouldn't evaluate paste for a wave process. I would use solder bar instead. Flux - top side fillets and no shorting on the solder side, does it clean well after processing if using water soluble flux. How wide is the process win

Hi, I curently have an interesting challenge. But I don't have all the knowledge to solve it. One of our boards is used in RF applications. We noticed that the No-Clean flux residue makes interferences in the RF signal. Removing the flux residue so

Brian: SMTnet has a "Terms & Definitions" section in the "Library." OA Flux. Flux, Organic Acid. A water soluble flux. Good luck Dave F

Graham, Please describe the term OA? I have never heard of that acronym. Thanks, Brian E. Steelglove
