High CTI 600V PCB
What is Comparative Tracking Index (CTI)?
Here CTI is a quality item that refers to copper clad laminate which is widely used in home electri
-cal appliance or other high-voltage (110V, 220V) electrical apparatus. It is a simulated condition
that the PCB is polluted in its working environment, which result in leakage or short-circuit at the
track gap of the PCB surface, being accompanied by heat releasing and charring.
The way of experiment is that continuous 50 drops of 0.1% ammonium chloride solution are
dropped between two points on the PCB surface, 30 seconds per drop, turning on high voltage
AC current to do the test. Firstly trying 300V to generate 1A current. There's ammonium chloride
solution on the surface, so after current is switched on it will produce resistance who also bring
out heat, then the solution is slowly evaporated. 2nd drop is on and till to 50 drops to see if the
PCB has leakage or not. Once the PCB has 0.1A creepage and exceeds 0.5 seconds, it's judged
Failure.
The quality of CTI of laminate refers to the externally applied voltage value and without failure of
50 drops. If abovementioned 300V passed, we can increase the voltage to 400V, 500V or 600V
till to the high value before failure. That is the data of the laminate CTI.
Bicheng offers high CTI PCB's (high CTI 600V FR-4 and aluminum backed material) which is
working in such harsh environment of high voltage, filth and humidity. | | IEC 112 standard has 3 degrees as follows | |
| | | Comparative Tracking Index (in Volts) | Class | | 600 <= CTI | I | | 400 <= CTI < 600 | II | | 175 <= CTI < 400 | IIIA | | 100 <= CTI < 175 | IIIB |
| |
As per the standard of IEC,the smaller a substrate of CTI grade, the better resistance to tracking.
Normal FR-4 ranges 175-225V
