For the selection of electrical characteristics, transparent insulation or transparent antistatic packaging tape is usually used for passive components, such as multilayer ceramic capacitors, tantalum capacitors, resistors, inductors and parts such as connectors and oscillators. The lower band of black conductive packaging is often used in transistors, diodes, ICs and any electrostatic sensitive components. –Antistatic packaging tape

There is no final conclusion as to what standard is used as the basis for selecting packaging materials. It generally depends on the user. Sometimes even for the requirements of the whole production line, some passive component or connector manufacturers will be required to use conductive or electrostatic dissipation packaging materials to avoid damage to other components caused by static electricity. —Antistatic packaging tape

In the production of electrical characteristics, in the past, most of them achieved the effect of anti-static or conductive by surface coating. For some lower belts with high quality requirements, the carbon powder conductive material is mixed in the plastic material, and the lower belt is made by the consistent forming method or the forming method after pressing the sheet, which can ensure the consistency of electrical characteristics.
