Isola 370HR is a lead-free compatible product and is considered to be a top-tier option within the industry, suitable for high-reliability applications across a wide range of markets. The laminate and prepreg are designed by Polycaldo and are made of patented high-performance 180°C Tg FR-4 multifunctional epoxy resin system, specifically tailored for multi-layer printed circuit board (PWB) applications requiring maximum thermal performance and reliability. Isola manufactures Isola 370HR PCB material laminate and prepreg using high-quality E-glass fabric with excellent resistance to conductive anode filament (CAF). Isola 370HR offers excellent thermal performance with low coefficient of thermal expansion (CTE) as well as mechanical, chemical, and moisture-proof properties that are equivalent to or better than those of traditional FR-4 materials.
The Isola 370HR prepreg and laminate are specifically designed for use in printed circuit boards, meeting RoHS requirements. One of the most common issues in PCBs is the occurrence of conductive anode wire (CAF), which is an electrochemical corrosion process. This phenomenon results in the dissolution and movement of copper metal from the anode to the cathode, potentially causing electrical shorts that are highly detrimental to any application, especially for networks and communications. However, the 370HR PCB is resistant to CAF. Additionally, it also provides high-density interconnections and boasts excellent thermal reliability.
1) Manufacturability:
For example, factors to consider include multiple pressing performance, temperature performance, CAF/heat resistance, mechanical toughness (adhesion) for good reliability, and fire rating.
2) Various performances (electrical, performance stability, etc.) matched with the product:
Consider low loss, stable Dk/Df parameter, low dispersion, small coefficient of variation with frequency and environment, and small tolerance of material thickness and glue content for good impedance control. If the wiring is long, consider low roughness copper foil. For high-speed circuit design, simulation in the early stage is necessary and the simulation result should be the reference standard for design.
3) Timely availability of 370hr material:
Many high-frequency plates have a long procurement cycle, even 2-3 months. It is important to communicate with the manufacturer in advance to prepare materials as soon as possible.
4) Isola370hr materials Cost:
Consider the price sensitivity of the product, whether it is a consumer product or a communication, medical, industrial, or military application.
5) Applicability of laws and regulations, etc.:
Integrate with environmental protection regulations of different countries to meet RoHS and halogen-free requirements.
Among the above factors, the operation speed of high-speed digital circuit is the main factor for PCB selection. The higher the circuit speed, the smaller the PCB Df value selected. The circuit board with medium and low loss will be suitable for 10Gb/S digital circuit; The plate with lower loss is suitable for 25Gb/s digital circuit; The board with ultra-low loss will adapt to faster high-speed digital circuits, and its speed can be 50Gb/s or higher.
Common high-speed PCB materials include:
1) Rogers: RO4003, RO3003, RO4350, RO5880, etc
2) Taiyao TUC: Tuc862, 872SLK, 883, 933, etc
3) Panasonic: Megtron 4, Megtron 6, etc
4) Isola: 370hr materials FR408HR, IS620, IS680, etc
5) Nelco: N4000-13, N4000-13EPSI, etc
