The ECT tape is a double sided, isotropically conductive pressure sensitive tape which conducts electricity through the thickness (the Z-axis) and the plane of the adhesive (X, Y planes). Provides good adhesion and electrical performance. It can turn any material into conductive material after attaching, then obtains the function of shielding, conducting or electrostatic discharge.
The one foot of the LED is pasted on the glass plate with ECT tape. At the same time, three button batteries are connected in series as power supply, and another tape is used to connect the power supply with the other foot of the LED. The LED is directly lit up.
