Limitations of Using Taconic RF-60TC PCB Materials

While Taconic RF-60TC PCB materials offer several advantages, it’s important to consider some limitations associated with their use:

1. Cost: Taconic RF-60TC is a high-performance material, and as such, it tends to be more expensive compared to standard PCB materials. The increased cost may be a limiting factor for projects with tight budget constraints or applications that do not require the material’s specific performance characteristics.

2. Availability: RF-60TC may not be as readily available as more common PCB materials. Availability can vary depending on the region and the specific supplier. This limited availability could potentially lead to longer lead times or challenges in sourcing the material for certain projects.

3. Processing Complexity: RF-60TC may require specialized processing techniques due to its unique properties. PCB manufacturers may need to adapt their manufacturing processes to accommodate this material, which could add complexity or require additional expertise. This could impact production timelines and costs.

4. Design Considerations: RF-60TC has specific electrical and mechanical properties that need to be considered during the design phase. For example, its lower profile copper option may have limitations in terms of current-carrying capacity compared to thicker copper options. Designers need to carefully evaluate and account for these factors to ensure optimal performance and reliability.

5. Material Thickness: RF-60TC may have limitations in terms of available thickness options. This can impact the design flexibility and may require additional considerations when designing PCBs with specific thickness requirements.

6. Environmental Considerations: While RF-60TC demonstrates good stability and reliability under normal operating conditions, it may have limitations in extreme environmental conditions. It is important to assess the material’s suitability for applications that involve exposure to high temperatures, humidity, or harsh chemicals.

It is crucial to thoroughly evaluate the specific requirements of the project and consider these limitations in order to make an informed decision regarding the use of Taconic RF-60TC PCB materials.

Storage and Shelf Life For Taconic RF-64TC PCB Laminates

Taconic RF-64TC PCB laminates, like most PCB materials, have specific storage and shelf life considerations to ensure their optimal performance. Here are some guidelines regarding the storage and shelf life of Taconic RF-64TC laminates:

1.Storage Conditions:

It is recommended to store Taconic RF-64TC laminates in a controlled environment that is dry, clean, and free from excessive heat, humidity, and direct sunlight. The storage area should be well-ventilated to prevent the accumulation of moisture.

2.Temperature and Humidity:

The ideal temperature for storing Taconic RF-64TC laminates is usually between 10°C and 30°C (50°F and 86°F). The relative humidity should be maintained below 50% to prevent moisture absorption, which could adversely affect the material’s electrical properties.


Taconic RF-64TC laminates are typically supplied in sealed packaging to protect them from moisture and contaminants. It is important to keep the original packaging intact until the laminates are ready for use. If the original packaging is compromised, it is recommended to transfer the laminates to a moisture-resistant and dust-free storage container.

4.Shelf Life:

The shelf life of Taconic RF-64TC laminates can vary depending on factors such as storage conditions and the specific requirements of the application. Generally, the shelf life is specified by the manufacturer and can range from 4 to 5 years from the date of manufacture. It is advisable to use the laminates within this specified shelf life to ensure their optimal performance.


When handling Taconic RF-64TC laminates, it is important to avoid exposing them to excessive bending, scratching, or impact, as these can damage the material and affect its performance. Additionally, it is recommended to follow any specific handling instructions provided by the manufacturer to prevent any potential issues.

How to Handling on Taconic RF-60TC PCB Laminates?

PTFE (polytetrafluoroethylene) is a thermoplastic material known for its reusability and slippery nature. When handling PTFE, care should be taken to avoid dropping or scratching the material. Over time, passive smoke particles may collect on the surface, darkening its appearance but not impacting its performance. PTFE is stable electrically and chemically, and it will not contaminate other materials or cause adverse effects. RF-60TC laminates are excellent for use with PTFE substrates as a substrate or top cover.

• When cleaning PTFE laminates, it is important to avoid mechanical scrubbing, brushing, or sanding. Instead, use a lint-free cloth to dust the surface, and refrain from using abrasive cleaners as the laminates are highly durable. Stainless steel wool should be avoided, as it may break at temperatures below 125°C (257°F), releasing silica dust that can cause allergic reactions.

• In the event of solvent contamination that cannot be removed mechanically, the laminate can be heated to 175°C (347°F) for a short period to evaporate the solvent and restore most of its strength.

• For removing solder mask from FR-4 PCBs, PTFE can be placed in water at 60 degrees Celsius (140 degrees Fahrenheit) for over two hours, after which the solder mask can be removed mechanically with tweezers.

• When handling PTFE laminates, avoid picking up panels horizontally by one end or edge. To inspect the laminate surface, a lint-free cloth moistened with water can be used to allow light to shine through, and a magnifying glass can provide the best results. Additionally, a glossy gold or silvery coating on the laminate surface is the result of an added metal layer.

• During fabrication and assembly, it is important to keep the laminates clean and prevent contaminant deposits on the material or copper. Avoid stacking panels directly on top of each other to maintain adhesion between the laminate surface and the PCB or PCB substrate, ensuring excellent performance of the printed circuit. Use a contact material between the PCB substrate and the laminate surface that maintains adhesion over a long period without causing damage.
