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.
3.Packaging:
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.
5.Precautions:
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.
