Atomic force microscopy (AFM) is increasingly being used as a nanoindentation tool to measure local elastic properties of surfaces. In this article, a method based on AFM in force volume (force curve mapping) mode is employed to measure the elastic modulus distribution at the interface of a glass flake-reinforced polypropylene sample and at a lead-free Cu-solder joint. Indentation arrays are performed using a diamond AFM tip. The processing of experimental AFM indentation data is automated by customized software that can analyse and calibrate multiple force curves. The analysis algorithm corrects the obtained force curves by selecting the contact point, discarding the non-contact region and subtracting the cantilever deflection from the measured force curve in order to obtain true indentation curves. A Hertzian model is then applied to the resulting AFM indentation data. Reference materials are used to estimate the tip radius needed to extract the elastic modulus values. With the proposed AFM measurement method, we are able to obtain high-resolution maps showing elastic modulus variations around a composite interface and a Cu-solder joint. No distinct interphase region is detected in the composite case, whereas a separate intermetallic layer (1-2 mu m thick) of much higher Young's modulus (similar to 131 GPa) than Cu and solder material is identified in the Cu-solder joint. Elastic modulus results obtained for the Cu (similar to 72 GPa), solder (similar to 50 GPa) and glass (similar to 65 GPa) materials are comparable to the results obtained by instrumented indentation [similar to 73, similar to 46 and similar to 61 GPa], which accentuates the potential of this method for applications requiring high lateral resolution.
