STOCKO shows zero tolerance

If you think that this is a negative characteristic here, you are wrong. Take a closer look and you will see that STOCKO's zero tolerance attitude is an essential condition for precise work. In this regard, the words zero tolerance can be taken quite literally. STOCKO recently acquired a state-of-the-art scanning electron microscope.

Small components, such as plug connectors and contacts, as manufactured by STOCKO do not tolerate any fluctuations in quality. Even the most minute manufacturing tolerances can subsequently result in the failure of entire assemblies. Because the requirements imposed on quality, service life, and the precision of STOCKO products are increasing over the entire cycle, continuous adaptation of our laboratory equipment is necessary to assure our high standards.

Consequently, as another step in expanding the development of our analysis methods STOCKO has placed a ZEISS EVO MA10 scanning electron microscope (SEM) with EDX system in service.

SEMs enable microscopic examination with magnification that is approximately 100x greater than that achieved with light-optical microscopes. Now 3-dimensional presentations of the most delicate surface structures possible, and it is also possible to measure and display elements that are embedded in the surfaces.

At STOCKO the SEM is typically used for the following applications:

With the SEM, new analysis possibilities are now available to STOCKO that contribute in improving the quality of STOCKO products, starting with product development and product qualification, in production monitoring and quality control, and extending to troubleshooting.
