Ahhhh, Dave, I'm glad I can still count on you for some real cutting edge info. yuck, yuck. Believe me, there's a lot more information available on how to resolve no-clean issues than there is on how to keep this stupid board wash/DI/Stencil wash/

Mikeh: You can't let that stuff get to your carbon bed. Literally, you can watch your bed die. The clay coats the carbon, entombing it. I've heard talk of using a RO filter as a front-end buffer to the recycling system, but know of no one who has

I cannot give references to papers, etc, but I can tell you from experience that High Impedance circuits and High Power RF circuits are not something to try no-clean on. For an aerospace customer, I had a circuit that any residue left between two pa

It realy depends on what no-clean you use, I had on that would get under IC's and not get fully activated it was fine here in the states but when it was shipped over seas the salt air and humidity gave us fits, another we used didnt have that problem

Chemistries are limited for WS Mask. Try looking/changing other components, trying different flux types is easy, identify water cleanliness, is it ionic/no-ionic...probably is benign. Could be a plating reaction which is tough to investigate. Call

Hi, We have solder reflow use with water soluble flux and Tin/lead process. There is special glass component which needs to mask during reflow soldering and wash flux+solder mask post soldering. The existing solder mask does washes off. But leaves

Have been playing with VOC free water based fluxes, so far they appear to come clean in an aqueous cleaner, I went to perform Ionagraph testing but our machine was down so I will let you know if they pass ionics.

The water soluble flux residue is staying there because the rinsing temperature it may be too low. The flux needs about 130-140 degrees celcius to become soft. If you are using water soluble flux, as per IPC A 610 standards it needs to be remove comp

Is there any harm in washing SMT soldered with NoClean paste? The PCA has some large thru-hole connectors that we would prefer to do as water soluble on out selective solder but the SMT consists of LGA's and other low parts that we would not be able
