What is the DS-7409HG(IQ) pcb material?
DS-7409HG(IQ) laminate is a halogen-free PCB laminate, widely used as the primary raw material in PCB fabrication. It is specifically designed for high performance applications that demand excellent thermal and mechanical stability. One of its standout features is its exceptionally high glass transition temperature (Tg) of 230°C, which ensures outstanding dimensional stability and minimal warpage under elevated temperatures.
The DS-7409HG(IQ) laminate demonstrates a dielectric constant of 4.3 at 1 GHz. The frequency significantly influences this value, with the dielectric constant decreasing as the frequency increases. A dissipation factor of 0.009 at 1 GHz implies reduced dielectric loss, ensuring minimal heat generation during signal transmission. This is of critical importance for applications demanding efficient performance in thermally challenging environments.
One such material that has been gaining wide attention in IC packaging is DS-7409HG(IQ) halogen free laminate. Known for its excellent thermal reliability, stable dielectric performance, and compatibility with standard PCB processing methods, DS-7409HG(IQ) represents a balanced solution for high-performance applications. It also explains why it is becoming a go-to choice for advanced IC packages such as FC BGA (Flip Chip Ball Grid Array).

The features of the DS-7409HG(IQ) PCB material
Glass Transition Temperature (Tg)
DS-7409HG(IQ) laminate features a high glass transition temperature of 230 degree celsius, this is very high. ensuring dimensional stability and resistance to thermal deformation during lead free soldering processes and under elevated operating conditions.
High Decomposition Temperature (Td)
With a high Decomposition Temperature (Td 380°C), DS-7409HG(IQ) laminate exhibits outstanding resistance to thermal degradation. This provides a crucial safety margin during soldering and ensures long-term reliability in high-temperature operating environments.
Dielectric Constant (Dk)
With a dielectric constant (4.3 @1GHz), the Dielectric Constant (Dk) of DS-7409HG(IQ) laminate is a measure of its ability to store electrical energy in a capacitor like manner. The material maintains a stable dielectric constant, which is essential for high quality pcb boards.
Dissipation Factor (Df)
With a dissipation factor (0.009 @1GHz), it has a low Df, which minimizes energy losses as signals travel through the PCB. A lower Df translates to less signal loss, which is reducing signal attenuation and enhancing efficiency.
Mechanical Drill Available
Unlike some fragile high-performance laminates that require laser drilling exclusively, it is compatible with mechanical drilling. This property reduces fabrication cost, simplifies processing, and makes it easier for manufacturers to adopt the material without investing heavily in specialized equipment.
High Elastic Modulus
The inherent stiffness of the laminate reduces the risk of damage during manufacturing, handling, and assembly. With its high elastic modulus, the laminate resists deformation during fabrication and assembly. This property ensures structural integrity, even in high density packaging with fine circuit features.
Halogen & Phosphorus Free
This laminate is fully halogen-free, antimony-free, and red phosphorus-free, it contains no antimony or red phosphorus, both of which are associated with environmental and health hazards. These attributes make it compliant with global RoHS directives, enabling manufacturers to meet eco-friendly standards without compromising performance.
Superior Heat Resistance
Another key strength of DS-7409HG(IQ) is its superior heat resistance. It withstands multiple soldering cycles and high operating conditions without deformation or delamination. This feature is critical for IC packaging, where the reliability of interconnects depends heavily on the substrate’s ability to resist thermal stress.
Similar to FR-4 PCB Processing
The laminate is compatible with standard FR-4 PCB processing techniques, which means no special tooling or new processes are required. This compatibility reduces transition costs for manufacturers while simplifying integration into existing production lines.
