“…Measurements at the microscale are challenging [29][30][31][32]: manual handling of the small objects may be difficult; the human eyesight is limited; contamination can easily impair tactile measurement results; objects at the microscale are often fragile. To assists the user during measurement setup, to protect and monitor the environment, and to feature cleaning and clamping systems, the developed microenvironment and tools are also here reviewed.…”

This paper describes the experimental verification of the novel IMT-PTB microprobe combined with a uniquely designed microenvironment. The microprobe consists of three silicon-based parallelograms stacked orthogonally, which leads to high isotropy. The probe tip deflections are detected in 3D with the help of piezoresistors placed in the parallelograms. The microenvironment facilitates and improves the measurement of workpieces with sub-millimeter features. The new microprobe and the microenvironment were integrated into a commercial coordinate measuring machine (CMM). To evaluate the microprobe performance, PTB produced and calibrated three reference objects: a cube, a sphere, and a microgear measurement standard. The differences between the calibration values and the measurement results obtained by the microprobe were in the sub-micrometer range. Furthermore, the microprobe was compared with the standard probing system of the gear measuring machine by measuring the reference objects with identical parameters. The results show the excellent performance of the micro probing system, thereby extending the capability of the CMM for high-precision measurements of complex workpieces at the microscale.

Compared with routine methods, dry ice cleaning is an innovative, inexpensive and green technology, which efficiently cleans printed circuit boards (PCBs) and decreases levels of ionic contamination. Due to its outstanding performance, dry ice cleaning is suitable for removing flux residues. In this study, boards that have been artificially contaminated by flux were blasted by dry ice with different parameters. The influence of dry ice cleaning on different surface finishes was comprehensively investigated. It was shown that the efficiency of dry ice cleaning is comparable with other methods and is quantifiable. Furthermore, dry ice cleaning can effectively remove pollution on PCB surfaces, yielding a noticeable and ideal cleaning effect without decreasing the solderability of different surface finishes.
