For high rate transmission, PCB boards must use laminates with a low Dk.
That is, if you want to achieve high frequency.
- Thermal expansion: thermal expansion refers to the ability of PCB material to change its appearance.
Normally, this is due to change in temperature.
PCB laminates are therefore prone to change their 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 PCB laminates consider laminates with copper and aluminum as they have high thermal conductivity.
- RoHS compliant: this refers to the ‘green’ requirement driven by market considerations and policies.
Basically, you should choose Taconic laminates which are RoHS complaint.

Let’s take a look at a few processes:
Taconic PCB Laminate
· Double-sided PCBs
For double-sided PCBs, the lamination process is quite similar to other types of PCBs.
You can laminate the double-sided PCB panel using a dry resist layer, which is photosensitive and under extreme temperature and pressure.
· Multilayer PCBs
Multilayer boards can be either thin etched boards or have trace layers.
Either way, they need bonding by lamination.
Processing Taconic laminates for multilayer PCB follows the following procedure:
i. The internal layers of the multilayer PCB are subjected to an extreme temperature of 375 degrees Fahrenheit and a pressure of between 275 and 400 psi.
ii. The multilayer PCB cures as the temperature is kept high.
iii. Finally, slowly release and slowly cool the lamination material.
· Sequential Lamination
This lamination technology is used if the PCB has two or more subsets.
After the subsets are created using a separate process, a dielectric substance is interposed between each pair of subsets.
Once this is done, standard manufacturing procedures are carried out.
You should choose a lamination process that is suitable for the intricacies of your application.
Are there Limitations of Taconic Laminates?
Limitations for Taconic laminates include:
- Processing high-performance Taconic laminates is not a simple business.

What Determines the Thickness of Taconic Laminates?
You can get the thickness of Taconic laminates by the fabric and density weight calculation.
You should expect to get some variance in your calculation as much as five percent.
Total weight is the most probable way of finding total laminate thickness.
A single fabric may possess different finished weight bringing about different finished Taconic laminates thicknesses when plied.
Therefore, to clearly determine the accurate thickness of Taconic laminates, you should always base your analysis on the final total weight.
Are Taconic Laminates suitable for High-Frequency PCBs?
Yes, Taconic laminates materials and many hybrid builds are often compatible making them suitable for high-frequency PCBs.
However, it is essential to put in place special circuit fabrication processing.

Taconic PCB laminate material
- Do not mechanically scrub the material as this will stretch and deform it.
To avoid this, the use chemical cleaning so as to achieve dimensional accuracy of the process and prevent distortion.
- Do not lift a Taconic laminate with one side up as you may cause the material to slide or stretch the copper.
Instead, you should lift the Taconic laminate using two parallel edges.
- Prevent contaminant deposits and staining on the Taconic laminate by handling it using protective gloves and slip sheets.
- Do not put Taconic laminates on top of each other. This is to avoid debris on the surface of the laminate.
How do you Process Taconic Laminates for Multilayer PCB?
Multilayer boards can be either thin etched boards or trace layers.
Either way, they both need bonding bay lamination.
Processing Taconic laminates for multilayer PCB adheres to the following procedures:
- The internal layers of the multilayer PCB are subjected to an extreme temperature of 190.56 degrees Celsius and a pressure of between 275 to 400 psi.
