ESD-Safe Masking Tapes
Removing liners from standard tapes can generate over 5,000 volts of static charge. These charged insulators, if brought into proximity with ESD sensitive (ESDS) devices, can cause immediate or latent damage.
The ANSI/ESD S541 standard dictates that process required insulators, such as tapes, must have accumulated charges <125 volts when used within 1” of ESD sensitive devices.
Polyonics ESD-Safe polyimide and polyester (PET) tapes fully comply with the ANSI/ESD S541 requirements for process required insulators and are safe to use within ANSI/ESD S20.20 IEC 61340 control plans.

Polyonics family of ESD-Safe polyimide and PET tapes provide surface resistances greater than 104 and less than 109 Ohms and low charging pressure sensitive adhesives (PSA) and liners that generate less than 125 volts when separated.
The tapes also provide high levels of dielectric strengths and are designed to remain dimensionally stable after exposures to high temperatures and harsh chemicals. All tapes come with liners for ease of handling and die cutting.
Polyonics ESD-Safe tapes have proven to help designers and manufacturers protect their most sensitive ESDS devices from electrostatic charges arising from both human contact (HBM) and charged devices (CDM) and have become valuable elements in the successful S20.20 ESD Control Plans of global electronics EMS’, ODMs, converters and OEMs.
Polyonics has worked with leading experts and consultants within the electronics community and ANSI/ESD S20.20 and S541 standards committees to develop a comprehensive white paper that not only defines the ESD problem and describes the certified industry test standards, but also offers guidance as to how best to reduce ESD risks associated with using process required insulators around static sensitive devices.In addition, comprehensive third party test data is also available for all Polyonics ESD-Safe materials.

- All tapes are REACH and RoHS compliant.
- All products are designed to be die cut with appropriate tooling.
- Clean/removable tapes are designed to remove from FR4 PCB and aluminum surfaces cleanly and with low peel forces.
- Light/removable tapes, depending on the severity of the process, may leave residue and have higher peel forces.
- Flame retardant tapes are not recognized by UL, but have been tested to the UL94 standard by Polyonics.
