What are the main properties of the anti-static heat sealing tape?

Anti-static heat-seal top tape refers to a tape product used in the field of electronic packaging. It is used in conjunction with a carrier tape. The cover tape is usually based on polyester or polypropylene film and is laminated or coated with different functional layers. (Antistatic layer, adhesive layer, etc.), can be sealed on the surface of the carrier tape under external force or heating to form a closed space to protect the electronic components in the carrier tape pocket.

The main performance indicators of the heat sealing tape:

Peel force:

Peeling force is the most important technical index for heat sealing tape. The placement manufacturer needs to peel off the cover tape from the carrier tape, take out the electronic components packaged in the pocket and install them on the circuit board. In this process, in order to ensure that the manipulator can be accurately positioned and the electronic components will not jump or turn over, the peeling force of the cover tape from the carrier tape must be sufficiently stable. The size of electronic components is getting smaller and smaller, so the requirements for stable peeling force are getting higher and higher.

Optical performance:

Optical properties include haze, light transmittance and transparency. Since it is necessary to observe the marks on the electronic component chip packaged in the carrier tape through the cover tape, there are certain requirements for the light transmittance, haze and transparency of the cover tape.

Surface resistance:

In order to prevent electronic components from being electrostatically attracted to the heat-seal top tape, the surface of the cover tape usually has antistatic requirements. The level of antistatic is expressed by surface resistance. Generally, the surface resistance of the cover tape is required to reach 10E9-10E11.

Tensile performance:

Tensile properties include tensile strength and elongation (stretch percentage). Tensile strength refers to the maximum stress that the sample can withstand before breaking. Similarly, elongation refers to the maximum deformation that a material can withstand before it breaks. Tensile strength is generally expressed in Newtons/mm (or MPa), and elongation is expressed as a percentage.
