Instead engineering samples were used, which had been manufactured on the same processing line as the standard traction devices with traction rated packaging materials (fig. 1).
The DUTs feature an AlN substrate, a copper baseplate and were produced by Mitsubishi Electric Corp. as engineering samples.
Nevertheless, these conditions are the industry standard and provide a benchmark for any kind of advanced testing, in particular, to extend the data base with respect to the investigations in [2,12].
Nevertheless, the consecutive testing with engineering samples can influence the statistical result and therefore, the result might change if the testing is repeated with fully qualified products in higher number.
Overall, PCT could be performed successfully on this engineering package and the corresponding pre-conditioning was applied to the devices.

Research and development needs to be carried out to overcome ITO drawbacks such as its brittle nature [17] to meet the requirements for advanced application in flexible electronic devices such as flexible dye-sensitized solar cells (FDSSC) [19,20] and flexible gas sensor [21,22].
