Function and usage of masking tape

Masking tape is on the copper foil, aluminum foil, or conductive cloth in the composition of the conductive adhesive tape, its role is to two pieces of different conductive metal parts connected up and its working principle is through the conductive adhesive tape in the metal particles and a tape of metal materials, and thus constituted a complete electrical conductor.
Because metal particles are normally embedded in pressure-sensitive adhesive, conductive adhesive is not conductive. When used, the metal particles should be pressed hard so that they can pass through the rubber layer before conducting contact with the metal parts. This is a must when using. In addition, the validation of an electrically conductive adhesive tape quality, also cannot directly measure the conductivity of conductive adhesive, and to connect two pieces of metal with conductive tape, then measured between two pieces of metal, the conductivity of the resistor as small as possible.
