hi
here are consolidated inputs to you you must validate before establishing your process.
ESD-safe Material: Ensure that the masking tape is made of ESD-safe materials that have low triboelectric charge generation. Common materials used in ESD-safe tapes include low-charging polyimide or polyester films.
ESD safe Workstation:- Establish the Proper Ioniser and ESD compliance, grounding at the work station.
Surface Resistance: Look for masking tapes with specific surface resistance properties, typically in the range of 10^4 to 10^12 ohms, which ensures they effectively dissipate any static charge.
Conformability: Choose a masking tape that conforms well to irregular surfaces and components, ensuring proper coverage during the conformal coating process without leaving any gaps.
Heat Resistance: Make sure the tape can withstand the curing or drying temperature of the conformal coating process without losing its ESD properties or leaving any adhesive residue.
Adhesive: Select a tape with an ESD-safe adhesive that provides strong adhesion during the coating process but can be easily removed without leaving any residue.
Clean Removal: Ensure that the masking tape can be cleaned and easily removed after the conformal coating process without lifting or damaging sensitive components.as well as PCB surface Masking.
Thickness: Consider the thickness of the tape; thinner tapes may provide better conformability, but thicker tapes might offer additional protection during handling.
Tested and Certified: Look for masking tapes that are tested and certified for ESD compliance by relevant industry standards, such as ANSI/ESD S20.20 or IEC 61340-5-1.
Labeling: Some ESD-safe tapes come with appropriate labeling, indicating their compliance with ESD standards. This helps easily identify them during the production process.
Storage and Handling: Ensure that the tapes are properly stored and handled to maintain their ESD-safe properties. Follow proper ESD handling procedures to prevent inadvertent contamination of the tapes.
Hope this information will help you to set your requirements. regards Shrikant India
