Neptune masters depths - non-destructive measurement of transparent coatings

Neptune masters depths - non-destructive measurement of transparent coatings

Many Mars missions might have been more successful if the coating on the electronic assemblies had been measured using a Neptune. But this is purely hypothetical. The fact is that under the extreme conditions of space some effects, such as Crystal growth, are favoured. Sealing the assembly is therefore particularly important here, because any dirt and moisture form the breeding ground for dendrite growth.

But electronics are also used on earth under extreme conditions. We don't even have to search hard to find locations like this: the engine compartment of our vehicles, offshore wind turbines, e-bikes and much more. The assemblies must be protected wherever it gets damp and dirty or where there is aggressive corrosion. But protection itself can become a problem.

On the unprotected assembly, dirt and moisture form a conductive mixture that shortens the insulation distances. The moisture also causes corrosion. The conformal coating is intended to protect the assembly from these dangers. However, if dirt and moisture are enclosed, the danger lies dormant under the supposed protection. Bubbles and air pockets are also predetermined breaking points in the protective layer.

These dangers can possibly be detected in a visual inspection, but not the invisible danger of incomplete curing of the coating layer. If the amount of coating applied is too high, there is a risk that the material will not cure completely. The remaining moisture creates the ideal conditions for dendrite growth and corrosion. It is therefore important to continuously measure the layer thickness so that the coating process is monitored. This is only possible with a non-destructive test with little expenditure of time - or better with an in-line test. Koh Young presents exactly these possibilities with his Neptune.

With the help of Laser Interferometry for Fluid Tomography, LIFT for short, the layer thickness of transparent media is determined within seconds. The webinar introduces the LIFT technology and shows the possible applications in the laboratory and in the in-line operation of a production facility.
