Isola manufactures prepreg and Copper Clad Laminates (CCL), the primary materials used in the construction of multilayer printed circuit boards. Prepreg is a dielectric material that provides electrical insulation and other properties, manufactured by impregnating fiberglass fabric with specially formulated resins.

CCL consists of an inner layer of prepreg laminated with copper foil. PCB fabricators use prepreg and CCL to construct multilayered PCBs through a complex process involving etching, layering, drilling, and plating to create intricate interconnection devices.

The stack-up configuration determines the electrical performance, signal integrity, impedance control, and thermal characteristics of the board. A typical multilayer PCB stack-up includes:

• Signal Layers: Copper traces carrying electrical signals
• Power and Ground Planes: Provide stable reference and distribution
• Prepreg Layers: Insulating material between signal layers
• Core Layer: Central layer providing mechanical strength
• Surface Layers: Outermost layers for component connectivity
• Soldermask and Silkscreen Layers: Protection and component markings

• Standard Multilayer PCB (4-8 layers)
• High-Density Interconnect (HDI) PCB
• Flex and Rigid-Flex PCB
• Sequential Lamination PCB
• Metal Core PCB
• RF/Microwave PCB

Multilayer PCBs are essential in:

• Consumer Electronics (smartphones, tablets, TVs)
• Telecommunications (routers, switches, modems)
• Automotive Electronics (engine control, ADAS)
• Industrial Equipment (control systems, robotics)
• Aerospace and Defense (avionics, radar systems)
• Medical Devices (diagnostic tools, imaging systems)
• Power Electronics (inverters, converters)
