Smart Electronics Immersion Gold Plated Gold Finger 6-Layer Impedance Matte Black PCBs

Immersion Gold Plated Gold Finger 6-Layer Impedance Matte Black PCBs are advanced printed circuit boards with several notable features.

These PCBs consist of six layers of conductive materials and insulating substrates. The matte black finish gives them a sleek and professional appearance while also providing certain advantages. The matte surface reduces glare and reflection, which can be beneficial in applications where visibility and readability are important.

The immersion gold plating on the gold fingers is a key feature. Gold is an excellent conductor of electricity and offers high reliability and durability. The gold plating ensures a low contact resistance and provides protection against corrosion and oxidation. This is especially important for connectors and interfaces where repeated mating and unmating occur.

The impedance control on these PCBs is crucial for proper signal transmission. By precisely controlling the impedance of the circuit traces, signal reflections and distortions can be minimized, resulting in improved signal integrity and performance. This is particularly important in high-frequency and high-speed applications.

The six-layer construction provides increased routing capacity and allows for more complex circuit designs. Different layers can be dedicated to specific functions such as power, ground, and signal routing, reducing interference and improving overall circuit performance.
