Circuit Board Wood Bowtie: 

Prior to the emergence of the printed circuit board (PCB), engineers often used point-to-point construction to create these hardware pieces. However, beginning in the early 1900s, printed circuit boards became the norm. In printed circuit board design, manufacturers use a variety of methods, including milling, to manipulate copper and other material layers to create sophisticated circuits on a circuit board. Chemical etching and manipulating material layers with precise laser technologies are other ways in which modern circuit boards are designed.
