Product Description

LINQTAPE PIT1N-B is a black high-temperature resistant polyimide film designed for both permanent and temporary bonding in many high-temperature applications. These applications can be found in semiconductor, smartcard, electronic, automotive, and general manufacturing industries. It is ideal for applications that require the balancing of multiple properties over a wide temperature range. LINQTAPE PIT1N-B film provides an excellent balance of electrical, mechanical, thermal, and chemical properties, and can be used in applications that may see temperatures up to 400°C. This film has an opaque black coloring, which results in almost no light transmission, higher heat resistance, and higher resistivity than the standard PIT1N.

LINQTAPE™ PIT1N-B Film comes in 33-meter (36-yard) rolls of varying widths. LINQTAPE PIT-N polyimide films without adhesive are available in a range of thicknesses, starting from 0.5 mil (12.7µm) thickness and up. Custom thicknesses are available upon request.

 

Key Features:

  • High-temperature applications
  • Thin film without adhesive
  • Excellent electrical properties

Film Thickness
Film Thickness
Film thickness is the thickness of a backing film without taking into account any coatings or adhesive layers. It is measured in micron and the conversion factor to mil is 0.039.

Total Thickness
Total thickness is taking into account all the films, coatings, adhesives, release liners and special layers and is the maximum thickness of a film or tape.

Electrical Properties
Breakdown Voltage
Breakdown Voltage
Breakdown voltage is the minimum voltage necessary to force an insulator to conduct some amount of electricity.
It is the point at which a material ceases to be an insulator and becomes a resistor that  conducts electricity at some proportion of the total current. 

After dielectric breakdown, the material may or may not behave as an insulator any more because of the molecular structure alteration. The current flow tend to create a localised puncture that totally alters the dielectric properties of the material.

This electrical property is thickness dependent and is the maximum amount of voltage that a dielectric material can withstand before breaking down. The breakdown voltage is calculated by multiplying the dielectric strength of the material times the thickness of the film.

Volume Resistivity
Volume Resistivity
Volume resistivity, also called volume resistance, bulk resistance or bulk resistivity is a thickness dependent measurement of the resistivity of a material perpendicular to the plane of the surface.

Dielectric Constant
Dielectric Constant
Dielectric Constant (k), commonly known as relative permittivity, is a number relating the ability of a material to carry alternating current to the ability of vacuum to carry alternating current.

It determines the ability of an insulator to store electrical energy and is the ratio of electric permeability in vacuum against the electric permeability of a material.

The lower the dielectric constant (κ) and dissipation factor, the less energy is absorbed from an electric field, making it a much better insulator.

It is a dimensionless property that can be affected by various factors such as the
thickness uniformity of a material, insufficient contact between the sample and electrodes, water adsorption and contact resistance.

Dissipation Factor
Dissipation Factor
Dissipation factor is commonly known as loss tangent or tan delta.



It is a ratio of the loss index and the relative permittivity and it measures the inefficiency of an insulating material to maintain energy (that otherwise dissipates in the form of heat). The lower the factor, the better the insulation.

It is the reciprocal of the quality factor and always refers to a specific temperature and frequency.

Mechanical Properties
Elongation
Elongation
Elongation is the process of lengthening something.

It is a percentage that measures the initial, unstressed, length compared to the length of the material right before it breaks.

It is commonly referred to as Ultimate Elongation or Tensile Elongation at break.

Tensile Strength (Thin Film)
Tensile Strength (Thin Film)
Tensile strength determines the resistance of a material to break under tension and it measures how much elongating load (or tensile stress) it can handle before fracture.

To make it simple, it measures how much force we have to apply when pulling apart a material before it breaks.
