Adhesive Film: A thin sheet or strip of a thermosetting or a thermoplastic resin.
Adhesive Preform: An epoxy created to a specific shape or drawing corresponding to its mating substrate.
B-Staged: Partially cured adhesive capable of a uniform bondline.
Capacitance: The ability of a material to store an electrical charge.
CTE: Coefficient of Thermal Expansion. The change in length per unit length for a one-degree change in temperature.
Dielectric Adhesive: An adhesive with negligible electrical or thermal conductivity.
Dielectric Constant: The measure of a material's ability to resist an electrical charge. It is a number corresponding to its resistance compared to the resistance of a vacuum (i.e. a dielectric constant of 1 indicates the material is as effective an insulator as a vacuum which we approximate, usually, with air.)
Electrically Conductive Adhesive: An adhesive capable of allowing the transfer of electricity through it.
EMI/ RFI Shielding: The protection of a substrate from magnetically induced voltage which degrades, obstructs, or repeatedly interrupts the desired performance of electronic equipment. The protection of a substrate from a high frequency, cyclic series of spikes or noise on an electrical line by means of radio wave energy or by a piece of equipment connected to the line causing undesired responses to or from other electronic equipment or systems.
Epoxy: Thermosetting resins capable of forming tight cross-linked structures characterized by strong adhesion and low shrinkage.
Gel Time: The amount of time it takes for the adhesive to begin curing.
Insulating Adhesive: An adhesive that prevents heat or conductivity from being transferred beyond its bond area.
Modulus: The degree to which a substance possesses a property. e.g. elasticity.
Substrate: The surface/material to which the adhesive is attached.
Tg: The glass transition temperature. The temperature at which material begins to flow from the solid state to a rubbery state.
Thermally Conductive: An adhesive capable of allowing heat transfer through it.
Viscosity: The property of resistance to flow in a liquid or semi-liquid.
