The term "4L HDI Flex 1OZ FR4 Rigid Gold Finger Printed Circuit Boards" refers to a specific type of printed circuit board with certain characteristics. Let's break down each component:
4L: This stands for "4-layer," indicating that the PCB has four layers of conductive material separated by insulating layers. Each layer can contain circuit traces and components.
HDI: HDI stands for "High-Density Interconnect." It refers to a design technique used to increase the circuit density and reduce the size of the PCB. HDI technology allows for finer traces, smaller vias, and tighter component placement.
Flex: "Flex" refers to the flexible portion of the PCB. A flexible PCB, also known as a flex circuit, is made of a flexible substrate material that allows the board to bend or conform to a specific shape. Flex PCBs are often used in applications where space or weight constraints are a concern.
1OZ: This refers to the copper weight or thickness of the copper foil used on the PCB. "1OZ" stands for 1 ounce, which is a common copper weight measurement. It indicates that each square foot of the copper layer weighs approximately 1 ounce.
FR4: FR4 is a widely used PCB substrate material. It stands for Flame Retardant 4, and it is a glass-reinforced epoxy laminate material. FR4 is known for its good electrical insulation properties, mechanical strength, and flame resistance.
Rigid: "Rigid" indicates that a portion of the PCB is not flexible. In this case, it refers to the rigid portion of the board, which is typically used for mounting components and providing structural support.
Gold Finger: "Gold Finger" refers to a specific type of surface finish on the exposed copper pads or fingers of the PCB. Gold is used because it offers excellent conductivity, corrosion resistance, and durability. Gold fingers are often found on PCBs that interface with connectors or sockets.
Overall, a 4L HDI Flex 1OZ FR4 Rigid Gold Finger PCB combines the advantages of a 4-layer PCB design, high-density interconnects, a flexible portion, a copper weight of 1 ounce, a rigid section for component mounting, and gold fingers for improved connectivity and durability. This type of PCB is commonly used in applications that require both flexible and rigid sections, such as certain medical devices, aerospace systems, and portable electronics.
