It is designed to withstand high temperatures and harsh operating conditions, making it ideal for applications that demand robust performance and longevity. The 370HR material is known for its low coefficient of thermal expansion (CTE), high glass transition temperature (Tg), and excellent chemical resistance.
Design Considerations for ISOLA 370HR PCB
Designing ISOLA 370HR PCBs involves several critical considerations to ensure optimal performance and reliability:
Effective thermal management is crucial to prevent overheating and ensure reliable operation. This involves considering the placement of heat-generating components and the use of thermal vias and heat sinks.
Maintaining signal integrity is essential for high-speed applications. Careful control of trace impedance, minimizing crosstalk, and using effective grounding techniques are necessary.
The design must account for the mechanical stresses the PCB will encounter during assembly and operation. This includes considering the board’s thickness, layer count, and material properties.
The PCB design should consider the potential exposure to chemicals and solvents during manufacturing and operation, ensuring the material’s compatibility and resistance.
Ensuring compliance with industry standards, such as IPC and MIL specifications, is essential for reliability and acceptance in various applications.
Materials Used in ISOLA 370HR PCB
ISOLA 370HR PCBs are made from a specific blend of materials designed to provide superior thermal, electrical, and mechanical properties:
The 370HR uses a high-performance epoxy resin system that provides excellent thermal stability, mechanical strength, and chemical resistance.
The laminate uses a woven glass fabric reinforcement that contributes to the material’s dimensional stability and mechanical strength.
High-quality copper foil is used for the conductive layers, providing excellent electrical conductivity and reliability.
The prepreg material, which is the uncured version of the laminate, is used to bond the layers of the PCB together during the lamination process.
Manufacturing Process of ISOLA 370HR PCB
The manufacturing process of ISOLA 370HR PCBs involves several precise steps to ensure high quality and performance:
The raw materials, including the epoxy resin system, glass fabric, and copper foil, are prepared and processed into sheets or rolls.
The laminate is created by bonding layers of copper foil and glass fabric impregnated with the epoxy resin system. This process involves applying heat and pressure to cure the resin and form a solid, stable laminate.
Circuit patterns are created using photolithographic processes. A photosensitive film (photoresist) is applied to the laminate, exposed to ultraviolet (UV) light through a mask, and developed to reveal the desired circuit patterns. The laminate is then etched to remove unwanted copper.
Vias are drilled into the laminate to create vertical electrical connections between different layers. These holes are then plated with copper to establish conductive pathways.
Multiple layers of the laminate are stacked and bonded together using prepreg material. The stack is then laminated under heat and pressure to form a multi-layer PCB.
A solder mask is applied to protect the copper traces and vias, and a surface finish, such as HASL, ENIG, or OSP, is applied to the exposed copper pads to enhance solderability and protect against oxidation.
The finished PCBs undergo rigorous testing and inspection to ensure they meet the required specifications for electrical performance, signal integrity, and reliability.
