June 2017 • The PCB Magazine 45 processes, is used very successfully in this appli- cation. Opportunities for standard car applica- tion are under evaluation. As these are mainly cost-driven functions, time will tell when high- end cars will install embedded devices for more robustness and higher functionality. Gold coins are one of the traditional meth- ods to save money and to avoid devaluation of any currency. Gold coins are also traded when cash is needed. However, it is not easy to de- fine whether the gold content is according to the book value of the coin. Many traditional test methods are taking the gold coins in wa- ter to define the volume. The volume of water and then multiplied with the specific gravity of gold. Although this is a traditional process, it takes time and experience of applying it. A company in Germany has developed an electronic unit (Figure 18) to define the pure gold content of a coin. An inductive test meth- EMBEDDING ACTIVE AND PASSIVE COMPONENTS IN ORGANIC PCBS Figure 16: Integrated connector inside a PCB with embedded devices. Figure 18: Testing the real gold in a coin.
