The low solids flux that is commonly called no-clean can affect some circuits. We are building a PCB that measures pico amps. The customer required that it be cleaned. We would rather used the low solids and eliminate a step. The customer had

Yer not making this easy. What kind of flux? If no-clean flux, what controls are you using to assure you are: * Applying the correct amount of flux? * Properly activating the flux? If water washable flux, talk to us about your cleaning methods and

I should have mentioned... the only flux we use for the hand soldering is wire-core, no bottle flux. I think it should be a non-issue to leave the activated wire core flux residue. I'm just looking for some way to prove it to the designer.

Grant, Why don't you try a water-base flux which is No-clean, VOC-free also? I have tried the 270WR flux from AIM with good results even on lead-free process. My $0.02, George

If the hand soldering is done right and you use little to no extra flux (other than whats in the solder wire) you should be ok. You should still verify with some testing however... You need to make sure any flux used is activated, thus rendered benig

Short of buying a closed look wash system, what other machines/processes are available for localized removal of flux that is not operator intensive. already familiar with Branson ultrasonics and just washing in alcohol but what else is out there?

Because our boards are heavily heatsinked with dow 340 which never hardens and I am afraid I will not only wash off the flux but the heatsink compound as well.

Just curious� Why only localized cleaning? Why not clean the entire board? Localized cleaning by nature is labor intensive. Mike Konrad Aqueous Technologies (909) 944-7771 ext 29 www.aqueoustech.com konrad@aqueoustech.com

I agree with dave here's an example of a previous thread on the subject. http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=6947&#Top

Mike, I totally understand your position. We find ourselves in two opposite camps. If no-residue was impossible my company would not be in business today. Lets focus on the topics so we can help people with their problems. Patrick
