Using the DSC test method, the Panasonic MEGTRON4 R-5725 PCB material has a
Tg value of 176 degrees Celsius. Also, for TMA and DMA test methods, the
Panasonic MEGTRON4 R-5725 PCB material has a value of 170 and 210
respectively.
While for the Panasonic MEGTRON4 R-5725 PCB material, it has a Tg value of 200
degrees Celsius Using the DSC test method. For the TMA and DMA test method, the
Panasonic MEGTRON4 R-5725S PCB material has a value or 190 and 215
respectively
This is the temperature at which glass transition occurs and it is usually lower in
contrast to the melting temperature of the material’s crystalline state. At this
temperature, the Panasonic MEGTRON4 R-5725 PCB material transforms from its
ductile look to one that is brittle and hard.
At the Z-axis, the Panasonic MEGTRON4 R-5725 PCB material has a Coefficient of
thermal expansion (CTE) value of 35 ppm/℃ at α1. While at α2, its CTE value is 265
ppm/℃. Also, for the X axis, they have a CTE value at α1 to be 12 – 14 ppm/℃,
while for the Y-axis, this material has a value at α1 to be 13 -15 ppm/℃.
Furthermore, for the Panasonic MEGTRON4 R-5725S PCB material, the CTE z-axis
has a value of 32 ppm/℃ at α1. While at α2, its CTE value is 250 ppm/℃. Also, for
the X axis, they have a CTE value at α1 to be 12 – 14 ppm/℃, while for the Y-axis,
this material has a value at α1 to be 13 -15 ppm/℃
This property indicates the extent at which a material can expand when it is heated.
Thermal decomposition
Both the Panasonic MEGTRON4 R-5725 PCB material and the Panasonic
MEGTRON4 R-5725S PCB material have the same thermal decomposition, which is
360 degrees Celsius.
The delamination time of the Panasonic MEGTRON4 R-5725 PCB material with
copper is 30 minutes. This same value holds for the Panasonic MEGTRON4 R-5725S
PCB material.
Note that delamination time has to do with the time required for the base material of a
printed circuit board to delaminate anytime it is subjected to a 288 degrees Celsius
temperature using TMA (Thermomechanical analyzer). Also, delamination refers to
separating each of the layers.
The dielectric constant for both the Panasonic MEGTRON4 R-5725 PCB material
and the Panasonic MEGTRON4 R-5725S PCB material is the same. At 10 GHz, they
both have a dielectric constant of 3.8. Dielectric constant refers to the quantity that
measures a material’s ability to store some electrical energy in a given electric field
The dissipation factor for both the Panasonic MEGTRON4 R-5725 PCB material and
the Panasonic MEGTRON4 R-5725S PCB material is the same. At 10 GHz, they both
have a dissipation factor of 0.007.
This value indicates the material’s inefficiency to act like an insulator. Furthermore,
this material has a low dissipation factor; therefore, it is very efficient as an insulating
material.
Peel strength
The peel strength of the Panasonic MEGTRON4 R-5725 PCB material and the
Panasonic MEGTRON4 R-5725S PCB material varies. For the Panasonic
MEGTRON4 R-5725 PCB material, its peel strength is 1.1 kN/m, while for the
Panasonic MEGTRON4 R-5725S PCB material, its peel strength is 1.3 kN/m.
Generally, this value helps in measuring the material’s bond strength, most likely an
adhesive.
The surface resistivity and volume resistivity of the Panasonic MEGTRON4 R-5725
PCB material and the Panasonic MEGTRON4 R-5725S PCB material are the same.
For surface resistivity, both materials have a value of 1 x 108 MΩ. For volume
resistivity, both materials have a value of 1 x 109 MΩ – cm.
Water Absorption
For water absorption, both the Panasonic MEGTRON4 R-5725 PCB material and the
Panasonic MEGTRON4 R-5725S PCB material have the same values. This stands at
0.14%. This has a low water absorption rate. This means that the material has what it
takes to remain strong, and prevent water absorption.
Flammability
For flammability, both the Panasonic MEGTRON4 R-5725 PCB material and the
Panasonic MEGTRON4 R-5725S PCB material have the same ratings. They are both
rated 94V-0. This rating ensures that there is electrical safety and fire protection of
the electronic components. 94V-0 means that the material has the ability to tolerate
some exposure to flame without any ignition.
