Hi Craig, so how long is a piece of string? As a generalisation, non-ionic surfactants used are; nonyl phenyl alkoxylates polyprop/polyeth ABA co-polymers alkylenic ethoxylates fluorinated esters The latter two are commonly used. If you want to give me more info I can perhaps help you more specifically. Take this offline if you want.

At the worst, it could be shut down altogether. I am looking for another source to do the testing of PWB's and Backplanes for conformance to our specifications and reliability needs. This testing includes cross-sectioning with analysis, XRF, thermal shock, pull tests, solderability evaluation, SIR/EM, SEM/EDX, and also FMA of assembled boards. Ideally, I am looking for someone within driving distance so that I can easily foster the relationship. However, I am open to any viable suggestions. If this is a testimonial from users please respond via the TechNet. If this is a lab promoting its capabilities, please contact me directly at [log in to unmask] Thanks in advance for everyone's input. P.S. I am also looking for a lab to provide me the direction, insight, foresight, enthusiasm, and overall experience that George Wenger at our Princeton Lab has provided me.
