Step 1
Engraving
Answer
Engraving is a process of cutting designs or text into metal surfaces using sharp tools. Different types of sharp tools are used to create a variety of designs. Often, power tools are utilized for engraving letters and numbers on ornamental objects, allowing for precision and intricate patterns.
Step 2
Printed Circuit Board (PCB)
Answer
A printed circuit board (PCB) is usually a plastic board about 1.6mm thick with a thin layer of copper on one side. This copper layer is etched away to create pads and strips that form electrical connections between various components. The components are then soldered to the pads, enabling the current to flow smoothly from one component to another.
