Abstract Based on the requirements regarding target, reproducibility, and specimen surface quality, an automatic system for controlled material removal and target preparation has been developed. The tool is for metallographic failure analysis of electric and microelectronic components, and provides an accuracy of 5 micrometer. This article presents details of sample preparation and device evaluation methods. The images presented show typical objects of examination in the analysis of microstructures and materials in the electronics packaging industry with brief comments. For automatically controlled material removal and preparation, the tool offers alignment and measuring of the sample prior to the preparation. The desired preparation layers were achieved precisely and reproducibly with several specimens of the same kind. The automatic preparation system allowed the preparation of critical samples within a short time, with high precision and with excellent reproducibility.

An automated process for the production and purification of radiometals produced by irradiating liquid targets in a medical cyclotron, using a commercially available module, has been developed. The method is suitable for the production and purification of radiometals such as 68Ga, 64Cu and 61Cu through irradiation of liquid targets and is important for producing high specific activity radioisotopes with a substantial reduction in processing time and cost when compared with the solid target approach. The “liquid target” process also eliminates the need for pre- and post-irradiation target preparation and simplifies the transfer of irradiated material from target to hotcell. A 68GaCl3 solution can be obtained in about 35 min with an average yield of 73.9 ± 6.7% in less than 10 mL of volume. 64CuCl2 solutions can be obtained with an average yield of 81.2 ± 7.8% in about 1 h of processing time. A dedicated single-use disposable kit is used on a commercial IBA Synthera® extension module.
