Self-adhesive solutions can cover all requirements for the electrical or thermal conductivity of a connection.
1. Electrical conductivity
Electronic devices and components can interfere with each other. Electrically conductive textile tapes (with EMC shielding) are used for EMI/RFI shielding and for grounding purposes in order to reduce or eliminate interferences caused by reflection and absorption. Furthermore, they are used to avoid electrostatic charges (potential equalization) and are suitable for the electrical field or electrostatic potential control of high voltage cables and transformers and for shielding. Electrically conductive copper and aluminum foils can be used, too, which can be equipped with conductive adhesives, for example acrylate adhesives. Those products can be used in testing laboratories for the development of prototypes and electronic designs. Special adhesive films provide conductivity in the Z-axis to connect printed circuit board tracks (conductive pads, isotropic and anisotropic absorbers, shielding, electrically conducting, ESD, RFI and EMC).
Aluminum foils offer good conductivity and sufficient EMI shielding properties. They have a low contact resistance and represent a cost-optimized alternative to copper foils. Copper foils have very high conductivity. They are particularly well-suited to shielding electromagnetic interferences and grounding. To optimize solderability, tin-plated adhesives can be provided.
2. Thermal conductivity
Thermal conductive adhesive films are used because of their good thermal conductivity in the bonding of heat sink components. In addition, they meet the requirements for vibration damping and gap closing. Thermal conductive adhesives can be processed easily and accelerate the production process. A very thin self-adhesive solution means low thermal resistance. Conductive silicone sheets ensure the thermal interface between electronic components and cooling surfaces. The conductivity is adjusted to customer requirements. Silicone sheets adapt to the surfaces under pressure and act as electrical insulators (interface pads, thermal management, heat-conducting and ceramic films).
