Product Description

4.0mm Multilayer PCB FR4 TG170 Immersion Gold 3u


A 4.0mm multilayer printed circuit board (PCB) refers to a PCB that has a thickness of 4.0mm and consists of multiple layers of substrate material and copper traces. Multilayer PCBs are used in applications where more complex circuits are required, and they allow for increased functionality and reduced size compared to single or double-layer PCBs.

FR4 TG170 is a type of substrate material commonly used in the manufacturing of PCBs. It has a glass transition temperature (Tg) of 170°C, indicating that it can withstand high temperatures during operation without losing its mechanical or electrical properties. This makes it suitable for use in high-temperature applications.

Immersion gold is a type of surface finish that is applied to the copper traces and pads on the surface of the PCB. It provides good protection against oxidation and other forms of corrosion, and it is commonly used in high-reliability applications.

3u refers to the thickness of the gold layer in the immersion gold surface finish. A 3u surface means that the thickness of the immersion gold layer is 3 microns, which is a standard thickness for many immersion gold finishes.

Overall, a 4.0mm multilayer PCB made with FR4 TG170 material and immersion gold surface finish with 3u thickness is a high-performance PCB suitable for a wide range of applications, including high-temperature and high-reliability applications. The specific capabilities and specifications of the PCB would depend on the manufacturer and the specific requirements of the application.
