What are the Main Features of the Doosan DS-7402LC PCB Material?
The main features of the Doosan DS-7402LC PCB Material include the following:
Low coefficient of thermal expansion
One great feature of the Doosan DS-7402LC PCB Material is its low coefficient of thermal expansion. This property (CTE) indicates the manner at which a material will expand for every 1 degree centigrade increase in temperature. This means that the material’s shape will not be significantly affected during any change in temperature.
High Temperature for glass transition
For those new to this, temperature for glass transition or glass transition temperature is the temperature whereby a specific material like the Doosan DS-7402LC PCB Material transforms from a one that is ductile to something brittle and hard.
For the Doosan DS-7402LC PCB Material, we can see that it has a high Tg. This once again proves that this material has high reliability.
Low dielectric constant
A material’s dielectric constant is very necessary for impedance considerations and signal integrity. These factors are very important and critical for high electrical performance.
The Doosan DS-7402LC PCB Material has a low dielectric constant, which makes it very useful for high power and frequency applications. This helps in reducing any loss of electric power.
Low Dissipation factor
Dissipation factor helps in measuring the insulating material’s inefficiency. This property also reveals how much or how effective a material will be in different environments and applications. This also indicates a material’s inefficiency to act like an insulating material or hold energy. The Doosan DS-7402LC PCB Material has a low dissipation factor. This means that its insulator system is more efficient.
