A friend in the electronics industry is having problems with residual solder flux giving rise to certain kinds of electrical noise in very high-impedance (G-ohm) circuits. Current manufacturing process is giving rise to unwanted product-to-product variation, and the company has no chemists on staff to address the problem. They've tried a variety of cleaning methods to remove residue, but they have not solved their problem. They are highly talented electrical engineers who have reached the limits of their expertise in this area, but help from a chemist familiar with the issues would be very welcome.
Contact me if interested. Thanks. - Josh
