Why Is The Dielectric Strength Important For Kapton PCB Materials?
Dielectric strength plays a vital role in maintaining sufficient insulation in Kapton PCB materials. This property refers to the highest electric potential that is required to break the insulating barrier in the PCB surface. That means the electron conduction becomes out of control if the voltage crosses the dielectric strength.
Kapton PCB materials ensure high insulating properties while carrying heavier current loads. Its typical value of the dielectric strength is 8000 V/mils for 0.05mils film gaze. This higher value makes it easier for the designer to maintain the balanced current flow and impedance control in these PCB applications. So, high dielectric strength is extremely important for a well-designed PCB assembly.
Excess current conduction causes overheating in the PCB layers. It lessens the longevity of electric circuits to a great extent. That’s why you need to consider the dielectric strength during the design of this PCB.
Today advanced electronic devices are ruling the world of technology. Kapton PCB has brought out a dimensional change in electronic appliances. Its reliable fabrication process, as well as versatile advantageous features, make large-scale productions easier.
