2.Detailed Specification

A "Multilayer Heavy Copper 2OZ~8OZ ENIG 2U' Rigid FR4 PCB Board" refers to a specific type of printed circuit board (PCB) with several characteristics. Let's break down each component:

Multilayer: This indicates that the PCB has multiple layers of conductive material separated by insulating layers. Multilayer PCBs allow for complex circuit designs with improved signal integrity, reduced size, and increased functionality.

Heavy Copper: "Heavy Copper" refers to the copper weight or thickness of the copper traces on the PCB. The term "heavy copper" is used when the copper weight is higher than the standard weight used in regular PCBs. Heavy copper PCBs are designed to carry higher currents and withstand higher temperatures. The copper weight can range from 2 ounces (2OZ) to 8 ounces (8OZ) or even higher.

ENIG: ENIG stands for Electroless Nickel Immersion Gold, which is a type of surface finish used on PCBs. The ENIG process involves depositing a thin layer of nickel onto the exposed copper surfaces, followed by a layer of gold. ENIG provides excellent solderability, corrosion resistance, and flatness of the surface.

2U': "2U'" refers to the thickness of the gold layer in the ENIG surface finish and is expressed in micrometers (µm). A 2U' thickness is relatively standard and offers good protection and solderability for the PCB.

Rigid FR4: "Rigid" indicates that the PCB is not flexible, providing a solid and sturdy structure. FR4 is a commonly used PCB substrate material made of a glass-reinforced epoxy laminate. It offers good electrical insulation properties, mechanical strength, and flame resistance.

In summary, a "Multilayer Heavy Copper 2OZ~8OZ ENIG 2U' Rigid FR4 PCB Board" refers to a rigid PCB with multiple layers, heavy copper traces ranging from 2 to 8 ounces, an ENIG surface finish with a 2µm gold thickness, and an FR4 substrate material. This type of PCB is suitable for applications that require high current-carrying capacity, thermal management, and durability. It is commonly used in power electronics, automotive applications, industrial equipment, and other demanding environments.
