What is the EM-370(D) PCB Material?
EM-370(D) is high-temperature,upper mid loss and halogen-free materials made from epoxy resin and E-glass fabric. It is standard FR-4 Dk and lower Df laminate,This Tg value can reach highs of 175 degrees centigrade. This range of eco-friendly materials aims to avoid halogenat ed resins due to environmental concerns about their potential hazards. These products are perfect for boards that need to withstand tough thermal cycles or heavy assembly processes. The laminates offer excellent chemical resistance, thermal stability for lead-free soldering, and CAF resistance.
EM-370(D) demonstrates superior electrical performance characteristics, making it suitable for various applications in electronics where reliability and efficiency are paramount. Its chemical resistance also contributes to its durability, ensuring that the PCBs maintain their integrity even when exposed to harsh environments or substances. It is meant to be used alongside EM-37B(D) prepreg for creating multilayer printed circuit boards, while EM-370(D) can also be used on single or double-sided applications. Applicable IPC Slash Sheets: IPC-4101 /127, /128, /130; IPC-4103 /250, /550.
The features of EM-370(D)datasheet

High Tg characteristics
The high Tg of 175 °C PCB material which is known for its elevated glass transition temperature (Tg), so that it possesses enhanced mechanical properties at elevated temperatures compared to standard polymers.
Upper Mid Loss performance category material
The PCB material is classified as a upper mid-loss performance category material, which indicates that it possesses specific electrical and thermal properties suitable for various applications in the electronics industry. This type of material is designed to provide a balanced performance profile, making it ideal for use in printed circuit boards where moderate loss characteristics are required.
Anti-CAF capability
This is another great property of EM-370(D) PCB material, this PCB laminate is CAF resistant. Conductive anodic filament (CAF) causes failures in PCB’s, and the PCB material is resistant to CAF and prevents failure in circuit board. The risk of CAF occurs when a metallic filament is formed from an electrochemical migration process.
Halogen free Pcb materials
EM-370(D) PCB material does not contain halogens, Halogens constitute a fascinating group of elements found in Group 17 of the periodic table, encompassing fluorine, chlorine, bromine, iodine, and astatine. These elements are often used in various chemical applications but can pose environmental and health risks when released into the environment. The PCB materials are designed to minimize harm during production, usage, and disposal phases. Often referred to as sustainable or eco-friendly materials, are substances that have a reduced impact on the environment throughout their lifecycle.
Lead-free assembly compatible
Materials meet lead-free assembly requirements and meet RoHS standards. The EM-370 (D) PCB material works fine with lead-free laminate materials. This makes them much safer when using them. This also means that you will make use of the EM-370(D) PCB material without having to worry about environmental pollution or hazardous substances.
Low Water Absorption
Another great feature of the EM-370(D) PCB material is its low water absorption rate. With this feature, water will not penetrate it. What we mean is that the EM-370(D) PCB material is useful in moisture-laden applications with less worry. This characteristic ensures that the integrity of the printed circuit boards is maintained over time, reducing the risk of corrosion and other forms of degradation that can occur when materials are exposed to damp conditions.
What is the Electrical Performance of the EM-370(D) PCB Material?
The electrical performance of the EM-370(D) PCB material is closely related to its dielectric constant and dissipation factor.
The EM-370(D) PCB material exhibits a dielectric constant of 4.1, indicating its significance in impedance considerations and signal integrity. Furthermore, it possesses a remarkably low dissipation factor of 0.015, highlighting its capability to store energy effectively while functioning as an insulator.
