As I mentioned earlier, copper traces are created by removing copper from the solid sheet that sits on top of the base material.
This means that the traces on your board are in fact just thin layers of copper. I don’t know about you, but when I discovered that it came as a bit of a surprise (relax I didn’t just find this out). For the longest time I assumed that PCBs were manufactured by pouring copper into a mold, letting it cool, and then somehow melting an insulator around the copper.
The thin sheet nature of these traces mean that there are some constraints to consider when routing your traces, most importantly, size considerations. All of these nuances will be discussed in detail in part 2.
Following will be continued in next chapter.
