Material?
The following properties below, shows what the Arlon 37N PCB Material has to
offer.
Physical Properties
The Arlon 37N PCB Material has the following physical properties. It has a
flammability rating of V0 as well as a thermal conductivity of 0.3 W/mk. Furthermore,
it has a density of about 1.6 g/cm3, as well as a water absorption value that is less than
1.0%
Thermal Properties
The Arlon 37N PCB Material has the following thermal properties. Its temperature
for glass transition is at 200 degrees Celsius.
Also, its decomposition temperature is 322 degrees Celsius at the initial. Then at a
weight loss of 5%, the value becomes 340 degrees Celsius. At 50 – 260 degrees
Celsius, the Arlon 37N PCB Material’s expansion along the Z-axis is 2.3%.
For the X, Y axis it has a coefficient of thermal expansion (CTE) of 17 ppm/C. The
T260 are all higher than 60 minutes, while for T300, T288, the values are 2 minutes
and 5 minutes respectively
Electrical Properties
The Arlon 37N PCB Material has the following electrical properties. Its dielectric
constant is 4.25 at 1 MHz. It has a volume resistivity of 8.2 × 109 MΩ-cm for
C96/35/90, while at E24/125, it has a volume resistivity of 4.7 × 109 MΩ-cm. Also, at
1 MHz, it has a dissipation factor of 0.018
Furthermore, this PCB material has an electrical strength of 52.4 kV/mm and an arc
resistance is 124 seconds. Its surface resistivity at E24/125 and C96/35/90 is 1.2 ×
109 MΩ and 4.4 × 106 MΩ respectively
Mechanical Properties
The Arlon 37N PCB Material has the following mechanical properties. Its Poisson’s
Ratio is 0.17 and its young’s modulus for CD/MD is 2.1 Mpsi or 14.5 GPa.
In addition, its peel strength with respect to copper is 1.2 N/mm after thermal stress.
Then at elevated temperatures, it stands at 0.9 N/mm, while after process solutions,
the value is 1.6 N/mm. Also, the tensile strength is 221 Mpa or 32 kpsi.
PCB Material
Due to the different storage conditions, you should dry the Arlon 37N PCB Material
at 736 mm Hg. This should be done between 12 – 24 hours.
Furthermore, the Arlon 37N PCB Material laminates properly either with hot start
or cold press starts. We recommend that you use either vacuum assist or the vacuum
assist lamination to get rid of air and moisture. Furthermore, low-flow materials don’t
remove air voids, same for standard prepreg. What vacuum will do is that it will
assure that the final product comes void-free.
For the lamination cycle, vacuum the package. This should be done for thirty minutes
and at 736 mm Hg, before you go ahead to apply pressure. Also, maintain this
vacuum beyond the resin’s set point i.e. above 160 degrees Celsius.
Make use of a platen temperature that falls within 370 degrees Fahrenheit and 380
degrees Fahrenheit. Also, control the rise in heat to 8 – 12 degrees Fahrenheit every
minute between 210 to 300 degrees Fahrenheit.
The pressure you should use should fall between 180 and 350 psi. This depends on the
complexity and size of the panel.
In addition, note that the cure time should be 9 minutes. Furthermore, subsequent
processing has to b e similar to those utilized in rigid flex printed circuit boards.
Material?
The applications of the Arlon 37N PCB Material include those where uniform and
minimal resin flow is important. Also this is useful during the attachment of heat
sinks to the polyimide MLBs. Also, it is applicable in bonding polyimide multilayer
rigid-flex.
Other areas where the Arlon 37N PCB Material is useful includes Industrial and
commercial PWB electronics, space, aerospace, and the military. This shows the
reliability of this PCB material.
