What Factors should you Consider when Choosing Taconic RF-35?

The following factors should be put into consideration when choosing Taconic RF-35:

Taconic RF-35 PCB

Taconic RF-35 PCB

  • Glass transition temperature refers to the temperature at which high molecular weight materials change from a glass state to a viscous rubber state.

You must consider the temperature into consideration because the rigid Taconic RF-35 will stop acting at this temperature and begins to behave softer.

  • Thermal decomposition temperature: you should note that the thermal decomposition temperature is different based on PCBs’ components.

For many epoxy systems, the temperature ranges between 300 degrees Celsius to 400 degrees Celsius for flexible Taconic RF-35 materials.

  • Dielectric constant: this refers to the rate at which an electric signal travels in a dielectric material.

It would be best to use laminates with a low DK to achieve high frequency for high rate transmissions.

  • Thermal expansion: thermal expansion refers to the ability to change its appearance due to a temperature change.

You should note that Taconic RF-35 is prone to change its shape, area, or volume when the temperature exceeds the Tg value.

  • Thermal conductivity: this is the ability of a material to conduct heat.

When choosing Taconic RF-35, you should consider those with copper and aluminum as they have high thermal conductivity.

  • RoHS compliant: this refers to the ‘green’ requirement driven by market considerations and policies.

It would help if you looked at RoHS compliance when selecting Taconic RF-35 as it has become a consensus among electronic manufacturers.

What does the PCB Lamination Process Entail?

The PCB lamination process will vary depending on the different types of PCBs and lamination specifications as elaborated below:

Double-sided PCBs

For double-sided PCBs, always note that the lamination process is quite like other types of PCBs.

It would help if you laminated the double-sided PCB panel using a dry resist layer that is photosensitive and under extreme temperature and pressure.

Multilayer PCBs

You may use bonding bay lamination to make multilayer boards, either thin etched boards or trace layers.

To process Taconic RF-35 for multilayer PCB, you may use the following procedure:

i. First, subject the internal layers of the multilayer PCB to an extreme temperature of 375 degrees Fahrenheit and a pressure of between 275 to 400 psi.

ii. You will see the multilayer PCB cure as the temperature is kept high.

iii. Finally, you can slowly release and slowly cool the lamination material.

Sequential Lamination

This lamination technology is useful if the PCB has two or more subsets.

After creating the subsets using a separate process, you may interpose a dielectric substance between each pair of subsets.

Once done, you can carry out standard manufacturing procedures.

You should choose a lamination process that is suitable for the intricacies of your application.

Is there a Recommended Thickness for Taconic RF-35?

The typical thicknesses for Taconic RF-35 that you may find will vary depending on the inches as follows:

The copper foil type that you may choose for Taconic RF-35 will be dependent on the following factors:

  • Power handling requirements: The board’s power handling requirements will determine the type of copper foil you should use.

For high power applications, you should use thick copper foil.

You should consider using the thin copper foils should if you have lower power applications.

  • Size and spacing: it would be better to use thinner copper foil when the lines are fine, and the spacing is narrow.

Sweeping lines and broader spacing, on the other hand, will require you to use thicker copper foil.

  • Characteristics impedance and loss of line: you must note that the cross-sectional area of the copper foil affects Taconic RF-35 thickness and it’s dialectic constant.
  • Heat: you should consider the amount of heat that needs to be handled as it will determine the copper foil type you need, especially in the inner layers.

Always have it in mind that thicker copper foils have a higher capacity to dissipate heat than thinner copper foils.

Is Taconic RF-35 Suitable for High-Frequency PCBs?

Yes, Taconic RF-35 materials and many hybrid builds are often compatible, making them suitable for high-frequency PCBs.

Thus, it is essential to put this in mind in the selection process.

  • You must consider the amount of resin that the fiberglass holds for filling and bonding.
  • It would be best if you looked at the circuit board’s thickness to select the most appropriate fiberglass.
  • The stiffness of the circuit board is also an essential factor that you may look at to obtain fiberglass, which is suited to the sole purpose of the Taconic RF-35.
  • The dielectric constant will help you choose the most appropriate fiberglass to use in Taconic RF-35.

Also, the regular dielectric constant for Taconic RF-35 is 3.5.

  • Dimensional stability of the Taconic RF-35 will help you choose the most suitable fiberglass for the purpose.
