PVA TePla Analytical Systems GmbH has been a ground-breaking expert in the field of acoustic microscopy for more than 30 years. With a range of leading solutions to suit all industries and fields of technology, we enable our customers to perform reliable non-destructive materials testing—from the inspection of solar and semiconductor systems all the way to failure analyses for ingots used in the production of wafers and MEMS systems.
To bring you all the advantages of acoustic microscopy at an outstanding price-performance ratio, we focus on creating a solid foundation. Every scanning acoustic microscope is based on a common component platform, which you can adapt and expand to the respective required system configuration at any time for specific applications. The long service life of our multi-channel systems guarantees you the best possible return on your investment.
Strict quality controls, highly-qualified engineers, and sales partners worldwide enable us to continuously further develop our technologies and processes. The focus in this case is on the resolution quality of our microscopes. Specially developed thin-film technology is used to create transducers with the world’s widest frequency ranges—from 3 to 2,000 MHz. Long-standing working relationships with leading research institutes (IMEC, Leti, Fraunhofer-Gesellschaften) contribute significantly to our shared success.
The foundation of acoustic microscopy
Development of “ELSAM,” the first ultra-high-resolution scanning acoustic microscope by Ernst Leitz, Wetzlar (subsequently Leica) with an operating frequency of 800 MHz.
The first SAM software
The first commercial V(z) module, a computer-based system for determining the velocity of surface waves (Rayleigh waves) using SAM, is unveiled.
The first acoustic microscope used in industry
Introduction of the SAM acoustic microscope with an operating frequency of 200 MHz for industrial applications.
These result in the creation of the first sapphire transducer for the detection of Rayleigh waves, based on ZnO-oxide technology.
Foundation of SAMTEC GmbH Aalen as a supplier of SAM systems in industrial SAM measurement and inspection technology.
