These copper circuits will be the conductors or electrical wiring on the board’s internal and outer layers. After the circuits have been etched and imaged on the laminate layers, they can be laminated using the prepreg described earlier. Soldermask, a green epoxy coating, covers the circuits ...
Affordability- Ceramic is a reasonably priced material. However, with all things considered, it is still more expensive than other materials used to make a traditional circuit board. It is a bit more costly in that case as its production requires special equipment. ...
