New Printed Circuit Boards from GETec available for fast surface measurements with ultra-long cantilevers

Ultra-long cantilevers of up to 5 mm were adapted via a newly designed PCB to the high performance AFSEM system developed by GETec Microscopy (www.getec-afm.com) (see Fig. 1). The electrical and mechanical connection is achieved with a simple yet robust plug connector, enabling an exchange of the cantilever with its compact PCB within seconds. This cantilever concept is especially useful for non-conventional AFM sensor applications like industrial on-machine quality control.

A second, improved design (Fig. 2) with optimized trace placing and a thinner and thus lighter PCB substrate has been produced and tested.
