The 3M™ Low Static, Non Silicone Polyimide Film Tape 7419 is a highly specialized tape crafted for PCB solder masking and other high-temperature applications where silicone contamination is a concern. Utilizing a non-silicone acrylic adhesive and DuPont™ Kapton® polyimide film, this tape provides exceptional performance in environments requiring stringent contamination control and static sensitivity.
- Non-Silicone Acrylic Adhesive: The specially formulated acrylic adhesive resists high temperatures typical in solder mask processes and removes cleanly without leaving residues, even after exposure to temperatures as high as 260 degrees Celsius (500 degrees Fahrenheit).
- Low Static Generation: Designed to produce very low static charge during both unwind and removal, making it ideal for use in static-sensitive applications, thereby protecting delicate electronic components from static damage.
- Chemical Resistance: The high-temperature acrylic adhesive also exhibits excellent chemical resistance, making this tape suitable for demanding chemical masking applications where other adhesives might fail.
- Silicone-Free: This tape’s non-silicone formulation is crucial for applications where silicone contamination can interfere with subsequent bonding or conformal coating operations, ensuring cleaner process outcomes and higher product reliability.
- Easy Removal: Engineered to remove cleanly from a variety of typical electronic substrates such as FR-4, polyimide, gold, copper, and silicon after high-temperature processing, thus ensuring smooth post-processing transitions.
- Eco-Friendly Core: The product is wound on a polyethylene tape core, offering an environmentally friendly alternative to traditional cores and enhancing the tape's overall durability and handling ease.
Usage and Maintenance: To achieve optimal performance, apply the tape to surfaces that are thoroughly clean, dry, and free of any oils or other contaminants. Regular checks are recommended to ensure that the tape maintains its integrity and effectiveness throughout its application, especially in environments with high temperatures and stringent cleanliness requirements.
