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.

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.

  • CTI>600V
  • Tg 135
  • Td 310

​High Tg, Halogen-free material

Due to the more and more strict RoHS requirements,many
​printed circuit boards have to use Halogen-free material.Especially
for some ​Intelligent devices.
For high layers board,high TG and Halogen-free is required.
10 layer PCB,HDI circuit boards must use this material.
