Those are the most basic printed circuit boards; all parts are concentrated on one side, while the wires are concentrated on the other.
Double Sides PCBs
Double-sided PCBs(Double-sided Printed Circuit Boards) are another traditional PCB with higher complexity than single-side ones. Double Sides PCBs’ architecture needs plating through holes between the bottom and top pads to provide better anchoring for soldered components. Today double-sided printed circuit board technology remains the workhorse of the assembly industry. There are unlimited applications for double sides PCBs. Fine line surface mount, ultra-high copper build, high/ low temperature, solder coating, and silver and gold finishes are a few common double-sided board applications.
Multi-layer PCBs consist of at least three or more circuit layers bonded together by a thickness of insulating material called prepreg and core. Multi-layer printed circuit boards are the most complicated ones and are generally used on the most sophisticated electronic product with their complexity in architecture and construction methods.
Standard PCBs are everywhere in our lives, like home appliances, LED lighting, and audio-visual equipment to computers used at the office, office equipment; storage, cars on the way; and medical equipment that provide us with a living guarantee; basic electrical equipment in the infrastructure like internet; telecom; and power supply guarantee us to have a better life.
