Can you make (modern) electronics with 1 conductor and 1 non-conductor on a ceramic printed circuit board? And what role does the computer play in making electronics?

Answer

Modern electronics still make extensive use of conductors and insulators (non-conductors), but crucial components such as diodes, transistors, chips, LEDs, and others are made from semiconductor materials. These are materials that only allow an electric current to pass under certain conditions – for example a sufficiently high temperature. Semiconductors contain a so-called forbidden energy zone that prevents electrons with insufficient energy from moving freely. Since this operating principle of semiconductors is so important to all modern electronic components, it is not possible to replace them with a combination of mere conductors and insulators. So the answer to the first question is ‘no’.

If by the second question you mean how computers are used in the production process of modern electronics, then the role is very large. After all, much electronics consists of microscopic components. These are first designed with the help of computers (including the design of printed circuit boards) and then created and assembled by means of (extremely precise) computer-controlled machines and robotics. Very specific software is therefore required for all steps in the process.
