As the saying goes, “time is money.” Many companies take this to heart and are always seeking methods of expediting and improving various processes, to reduce the total time.
In terms of indentation testing, speed, efficiency and precision can be integrated into a quality control or R&D process when using one of the Nanovea Mechanical Testers. This article showcases an efficient way of saving time using the Nanovea Mechanical Tester and Broad View Map and Selection Tool software features.
Importance of Broad View Map/Selection Tool
It can be challenging to perform fast, precise and targeted indents on a surface(s) whilst also trying to obtain information from a sample with small patterned or random scattered features of interest. By using the Broad View Map and Selection Tool, the user can save time through the creation of a two-step macro recipe that maps a surface with targeted small and/or random features of interest that the user selects.
The map can then be used to perform all indents sequentially without any further user interfacing. The ability to target micro and nano-scale features could bring potential benefits to multiple industries such as jewelry, powder manufacturers, microelectronics, minerals, and MEM, as well as many others. Particles, small etched features, and grains can all be targeted using this method.
Multi Module Platform
3 Testing Modes in 1 (Scratch/Indent/Wear)
Loading Ranges from 0.8 uN to 400 N
XYZ Motion with 0.20 um Step Resolution
Fully Automated (Up to 100 indents in 15mins)
Integrated Imaging (Prolometer, AFM, Microscope)
In the study discussed in this article, the Nanovea PB1000 Mechanical Tester was used to target ink letters on a circuit board and micro-size patterned etched features to showcase its positioning precision.

About the Method
The Broadview Map Selection Tool requires the user to first locate the area of interest, map the area and then isolate the areas they want to target. The software saves each area in coordinate form in reference to your current location. The software will ask you to input the desired testing parameters for each selection, allowing the tests to be performed with recurring and/or different testing parameters.
This is particularly useful if the user needs to troubleshoot the indentation testing parameters of the application. For the circuit board shown below, Nanovea could easily target the central regions along the lettering without issue. The positioning versatility of the Broadview Map Selection Tool lets the user determine the mechanical properties of a sample at various locations of a component at random targeted locations.

The image below is of the first step in creating a macro recipe using the Broadview Map Selection Tool and the resulting indentations. The user selects all features/areas of interest in any order, which are then automatically indented by the instrument.

This study showcased the ability of the Nanovea Mechanical Tester and the Broadview Map Selection Tool to indent specific areas of interest with high-precision position control. This combination gives the user endless possibilities when targeting desired features. There is also the ability to target specific areas for quality control tests. The ease of use and reliability is clearly seen in Nanovea’s instrument.
