1. 8 Layers Prototype Printed Circuit Board further expands the density and complexity of PCB design by adding additional layers beyond the top and bottom layers seen in the two-sided configuration. Multi-layer printed circuit board configurations can cover multiple layers, and multilayer PCBs allow designers to design very thick and highly composite.
2. The extra layer it uses in the design is the power plane. The power plane both supplies power to the circuit and reduces the level of electromagnetic interference emitted by the design. 8 Layers Prototype Printed Circuit Board achieves lower EMI levels by placing the signal level in the middle of the power plane.
3. Its surface is made of copper to ensure efficient current flow. These metals require proper protection of the components to avoid oxidation and other corrosion. A range of surface treatment types provide varying degrees of protection against degradation. They also contribute to certain uses, such as welding.
4. 8 Layers Prototype Printed Circuit Board has many circuit layers between the top side and the bottom side, and each layer can also be connected by PTH (Plated Through Hole), which is more complicated than a double-sided PCB. It has been tested for E-tests, automated optical inspection, X-ray, camera-controlled drilling and impedance control, so the quality is very good.
