The difference between the double lead copper foil tape and the single lead copper foil tape is described in detail
Knowledge development: shielding material series conductive copper foil tape; single and double conductive copper foil tape, thickness 18U-25U-35U-50-70U-85U, long 50M, width, arbitrary, can be cut into irregular shapes. It is an indispensable accessory for the electronic industry. Main use, transformer, mobile phone, computer, electronic products shielding application and so on.
The double conductive copper foil tape has a conductive acrylic adhesive on one side, and both sides have electrical conductivity.
Single lead foil tape back side non conductive acrylic adhesive, adhesive surface with conductive performance.
It can be identified from the following two aspects:
1, appearance: double lead foil tape, adhesive surface containing fine particles (metal particles, conductive effect), slightly uneven; single guide surface of fine particle copper foil adhesive, flat;
2. Test: a low resistance tester is used to measure. The resistance value of the double conductance is 0.01-0.03 ohm, and the single guide will not pass through the current.
