What is the EM-888K PCB material?
EM-888K is High-Tg, Very Low Loss and Halogen-free materials made from epoxy resin and E-glass fabric. This Tg value can reach highs of 170 degrees centigrade. This range of eco-friendly materials aims to avoid halogenated 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. And the EM-888K is designed to meet RoHS compliance standard.
EM-888K 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. EM-888K is meant to be used alongside EM-888BK for creating multilayer printed circuit boards, while EM-888K can also be used on single or double-sided applications.
The features of EM-888K data sheet
High Tg characteristics
The high Tg of 170 °C EM-888K 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.
Very Low loss performance category material
The High Speed PCB material is classified as a Very low 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 Very low loss characteristics are required.
Anti-CAF capability
This is another great property of EM-888K PCB material, this PCB laminate is CAF resistant. Conductive anodic filament (CAF) causes failures in PCB’s, and the 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 materials
The EM-888K is a type of material that is classified as halogen-free, meaning it does not contain halogen elements such as fluorine, chlorine, bromine, iodine, or astatine. The 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 high tg 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-888K PCB material without having to worry about environmental pollution or hazardous substances.
Low Water Absorption
Another great feature of the EM-888K PCB material is its low water absorption rate. With this feature, water will not penetrate it. What we mean is that the 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.
