Alternatively, six-month shelf life is possible for VT-47 Prepregs with temperatures below 5 0C and no relative humidity.

Contrariwise, a VT-47 Laminate can be kept for up to 24 months in airproof packaging at room temperature.

How do you Test the Flammability of Ventec VT-47 Laminates?

Flammability is a material property determined by igniting the material and observing how long it combusts before extinguishing.

The flammability of Ventec VT-47 is significant due to the heat-intensive nature of some applications.

You find some applications where Ventec VT-47 is used to have large power demands and consequently large heat dissipations.

Consequently, flammability helps you realize the ramifications of such an environment to your Ventec VT-47 beforehand.

Also, you carry out a flammability test for Ventec VT-47 by using a specimen size of five inches by half an inch.

You extract this specimen from a Ventec VT-47 with the smallest allowed thickness.

Depending on the application, the classification you provide for the Ventec VT-47 will vary.

Applications with higher thermal dissipations will require the Ventec VT-47 to be the most flame-retardant and the opposite is true.

You subject the specimen to flames with different intensities dictated by the source of ignition.

You then note the time taken for the specimen to combust and eventually extinguish for each ignition.

For you to achieve a higher classification, you employ more intense ignition sources to increase the flame’s potency.

What are the Press Conditions for Ventec VT-47?

You make Ventec VT-47 via a lamination process that presses together the distinct layers under specific pressing conditions.

Besides, you find the conditions facilitating the pressing process are significant in ensuring the interlayer bond is strong.

The conditions that you find essential for good press for Ventec VT-47 are:

  • The rate at which the material is heated is maintained within manageable levels.

You find it maintained between 1.5-3 0C/min for automated press and between 3-6 0C/min for the manual press.

  • A curing temperature of over 185 0C with a curing period of over sixty minutes.
  • The pressure in the laminating chamber should be equal to or greater than 300 psi.
  • There is continuous vacuuming until the material temperature exceeds 140 0

What is the Temperature of Glass Transition for Ventec VT-47?

Ventec VT-47 Laminates/Prepregs have a relatively high temperature of the glass transition.

The temperature of glass transition is that at which the VT-47 softens acquiring glass-like properties.

For Ventec VT-47, you will observe the temperature of glass transition at about 170 0C.

However, you are more likely to experience a glass transition of VT-47 at 180 0C.

Do Ventec VT-47 Products Experience Thermal Stress?

When working with electronic products, you observe thermal stress as an issue that is addressed by the choice of material.

Thermal stress occurs as a result of the accumulation of generated heat on a surface resulting in a temperature rise.

You find a major cause of heat dissipation in wiring boards to be the amount of current conducted.

Consequently, to stave off the undesired effects of thermal stress, you need a thermal management system in place.

When working with Ventec VT-47, you note that thermal stress can be experienced when temperatures exceed 288 0C.

There is a need to intervene as when the temperature is sustained for over ten seconds, chances of failure increase.

Can the Temperature of Glass Transition Affect the Z-axis CTE of Ventec VT-47?

The coefficient of thermal expansion is an expression of the response of a material to temperature changes.

You can express the z-axis thermal coefficient of expansion before and after the temperature of glass transition.

You find the change in the z-axis before the temperature of glass transition is achieved to be smaller than after.

Consequently, a Ventec VT-47 will exhibit more significant dimensional change when the temperature exceeds that of the glass transition.

What is Volume and Surface Resistivity in Ventec VT-47 compare?

You determine that surface resistivity and volume resistivity as expressions of a non-conductive material’s resistance to leakage current.

Surface resistivity is specific to the resistance exhibited on the material’s surface whereas volume resistivity highlights resistance through the material.

You note Ventec VT-47 is employed as a dielectric layer in PCB construction required for electrical isolation.

Also, you find Ventec VT-47 to be with high surface and volume resistivity to minimize the penetration of leakage current.

You find resistivity and leakage current to be indirectly related hence a higher resistivity amounts to a lower leakage current.

Consequently, when VT-47 is made with high resistivity, you note its isolation performance is impressive due to reduced leakage current.

Does Moisture affect the Electrical Performance of Ventec VT-47?

Ventec PCB

Ventec PCB

You employ Ventec V-47 in wiring board construction as a core providing electrical isolation for the conductive copper layer.

You find VT-47 possesses high surface resistivity preventing entry of leakage current that can initiate current movements.

However, when you expose it to moisture content, the resistivity of the VT-47 is impaired allowing passage of current.

Moisture ionizes creating a path for the leaked current interfering with the non-conductive property of the VT-47.

You, therefore, find it imperative to make Ventec VT-47 with low moisture absorption capability.

A low absorption rate of moisture allows the VT-47 to maintain its poor conductivity.

What are some of the Drilling Parameters useful for Ventec VT-47?

Drilling is an important fabrication aspect of Ventec VT-47 which you perform with high precision and is expensive.

You find drilling allows holes designed for component placement and interlayer passage to be bored.

Also, you find automated drilling procedures necessary for Ventec VT-47 as the process is heavily controlled and monitored.

Additionally, when you use drill bits with undercutting, you can achieve impressive hole quality, especially for small holes.

Important parameters when carrying out the drilling process are:

  • Speed of the spindle
  • Rate of feed
  • Rate of retraction
  • Chip load
