PCB Material 

Printed circuit board is the most important part of electronics. The PCB material is the most cost of the whole PCB. So,before PCB design, you need to know which material is the best for your product.PCB design is just a first step,you also need to know the  application environment of PCB,such as outdoor,underwater,high temperature.Good meterial can support long life for your eletrical equipments.
Storm Circuit has many different materials for you to choose. What customers need,then we will do .

High CTI 600V PCB

CTI is Comparative Tracking Index.
​CTI is a quality item that refers to copper clad laminate which is widely used in home electrical appliance or other high-voltage(110V, 220V) electrical apparatus.It is a simulated conditon 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.
