3.1 Comparison of Dielectric Strength
The dielectric strength of an insulating material is a crucial parameter that determines its ability to withstand electrical stress without failure. In the case of circuit board insulation, tapes with high dielectric strength are essential to prevent electrical breakdown and ensure the long-term reliability of electronic devices
1
3
. Table 1 presents a comparative analysis of the dielectric strength of LVMEIKAPTON insulating electrical tape and other commonly used alternatives such as Adhesive PET material high temperature tape.
Table 1: Comparison of Dielectric Strength (kV/mm)
-----------------------------------------------
Tape Material     | Dielectric Strength (kV/mm)
-----------------|---------------------------
LVMEIKAPTON Tape | 100 - 120
Adhesive PET Tape| 60 - 80
Polyimide Tape   | 80 - 100
Epoxy Composite  | 70 - 90
-----------------------------------------------
As shown in Table 1, LVMEIKAPTON tape exhibits a significantly higher dielectric strength compared to Adhesive PET material high temperature tape. This superior performance can be attributed to the unique chemical structure of the polyimide material used in LVMEIKAPTON tape, which has a high molecular weight and excellent resistance to electrical degradation
8
. In contrast, Adhesive PET tape has a lower dielectric strength due to its lower molecular weight and susceptibility to mechanical stress under high electrical fields

The purpose of the thermal cycling test is to evaluate the performance stability of PI material high temperature resistant 300 tape under extreme temperature conditions, which is of great significance for predicting its reliability in actual applications. The experiment was carried out using a programmable high - low temperature test chamber, which can accurately control the temperature range and cycling rate. The specific steps of the experiment are as follows: First, prepare samples of PI material high temperature resistant 300 tape with a standard size of 100 mm × 10 mm, and ensure that the surface of the samples is clean and free of defects. Then, place the samples in the high - low temperature test chamber and set the temperature cycle parameters: the temperature ranges from - 40°C to 150°C, with a temperature change rate of 5°C/min and a dwell time of 30 minutes at each extreme temperature point. Each cycle lasts for 2 hours, and a total of 100 cycles were performed. During the experiment, the insulation resistance and dielectric strength of the samples were measured at regular intervals to monitor their changes. In addition, the appearance of the samples was observed after the experiment to record any signs of deformation, cracking or discoloration. This experimental design strictly follows the relevant industry standards to ensure the scientificity and repeatability of the results

The experimental data show that PI material high temperature resistant 300 tape exhibits excellent performance stability in thermal cycling tests. After 100 cycles of thermal shock, the insulation resistance of the sample decreased by only 8%, from the initial value of 1 × 10^14 Ω to 9.2 × 10^13 Ω, indicating that its insulation performance remains at a high level. At the same time, the dielectric strength of the sample decreased from 50 kV/mm to 45 kV/mm, with a decrease of 10%, which is still within the acceptable range. In terms of appearance, the sample showed no obvious signs of deformation or cracking, and only a slight discoloration occurred, which did not affect its overall performance. These results indicate that PI material high temperature resistant 300 tape has outstanding thermal stability and can maintain its key performance indicators in a wide temperature range. Compared with other similar products, its advantages are more prominent. For example, some ordinary insulating tapes may experience a significant drop in insulation resistance or even lose their insulating properties after a similar number of thermal cycles. The excellent performance of PI material high temperature resistant 300 tape is mainly due to its unique molecular structure and high - temperature resistant material formulation, which effectively resist the damage caused by repeated thermal expansion and contraction
