Yes, the technology exists. The technique is SERA (Sequential Electrochemical Reduction Analysis). The instrument is manufactured by ECI technology, based on the work of Dr. Morgan Tench. It works by using an electrolyte and applied current to reduce oxides. By monitoring the potential (voltage), current and time, the amount and type of oxides can be deduced.
There are limitations on the size and configuration of surfaces that can be tested, and a knowledgeable analyst is required to interpret the results.
For production testing, a more functional test is often used, that is, an actual soldering test. Bear in mind that a functional test has the advantage of being a direct indication of the effect on soldering performance, but has the disadvantage that it does not point to root cause. The analytical technique (SERA) has the advantage of pointing to root cause, but at the cost of not providing any direct information on how actual production soldering will be impacted.
