discovered that heat made copper more malle-able. Casting and smelting of copper began around 4000-3500 B.C. (see figure 6-2). About 2500 B. C., copper was combined with tin to make bronze—an alloy that allowed stronger weapons and tools. Brass, an alloy of copper and zinc, probably was not developed until 300 A.D.
The search for copper during this early period led to the discovery and working of deposits of native copper. Sometime after 6000 bce the discovery was made that the metal could be melted in the campfire and cast into the desired shape. Then followed the discovery of the relation of metallic copper to copper-bearing rock and the possibility of reducing ores to …

Double-sided PCB is the most used and preferred type of PCB because it is neither complex like a multilayer PCB nor simple like a single-layer PCB.It lies in between these two categories and is used in a wide range of applications. Double-sided PCBs have two layers, one on each side. The stack-up is quite simple as there are no inner layers. The …
The design of a PCB is an important step in the PCB production process and it is usually referred to as PCB design or PCB layout.
