Thermal Conductive Board (TCB), or Insulated Metal Substrate (IMS), provides the advantages of high thermal conductivity, reliability
and solder heat endurance. The TCB substrate is a sandwich structure, which includes layers of conductor, insulator and metal base.
Traditionally, this insulator is made of epoxy, epoxy filled glass fiber, polyimide, or other dielectric materials. However, these kinds of
insulators could not meet the requirement in high-power electronic devices. The heat generated by these devices will accumulate, and
the life time and reliability of the end product will decrease

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.

PCB Material Center
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 .

The key parameters for PCB material are Tg,Dk,Df,CTE,etc. Here we have a PCB material's parameters list for you to reference.
To select the right PCB material, you need to see a few factors. If you know about the factors that you need to look at, then you can easily get the best PCB material for your project, and the PCB will provide the required results. You can also talk to the PCB manufacturer or fabricator about these factors. Let’s look at the factors that are essential to consider while selecting a PCB material.
A) Tg:Glass Transition Temperature
The substrate should have a high glass transition temperature (Tg). A high Tg can deal with heat dissipation and ambient temperature. You must select those materials that have a higher Tg than the circuit temperature. Otherwise, the substrate will melt down or bend during the operation. >=8 layers PCB,Storm PCB must use >Tg170 PCB material .Tg150 or less is not safe for high layer PCB.
B) CTE:Coefficient of Thermal Expansion
The PCB material should have a low coefficient of thermal expansion. If the coefficient is high, then it will expand more per unit increase in temperature. This will affect the length, width, and thickness of the PCB board. The PCB will change its shape easily and may cause damage to the board and components. Make sure to select the material that has a low coefficient of thermal expansion.
C) Heat Resistance
High heat resistance is required. Generally, PCB must have a heat resistance of 250 ℃ / the 50S. If you need more heat resistance, then you can discuss it with your PCB manufacturer.
There should be excellent flatness. The warpage should be less than 0.0075mm / mm.
E) Dielectric Constant and Losses
The PCB material should have an excellent dielectric constant. It will provide excellent insulation and offer the desired results. Moreover, the dielectric losses should be low to save energy.Dk and Df is very important for high frequency PCB.very low loss is usually RF material ,Rogers RO400.
F) Degree of Bending
The PCB should not bend easily. If it bends on the ambient temperature of the device where it is installed, then it will wear quickly. It will not last for a long time. Therefore, the PCB should have a low degree of bending so that it cannot bend on the circuit operating temperature. Its heat resistance should be high, depending on the place where it will be used. Some substrates, like FR-4 have a low degree of bending, which is suitable. The degree of bending matters a lot when the PCB is larger than 3.2 × 1.6mm. Due to the large size, it is affected more due to bending. So, you need to be more careful in the case of large PCBs. Moreover, the appearance is required to be smooth and flat without warpage, cracks, scratches, and rust.
Also,there are many other factors,such as voltage (if you apply in high voltage,CT>600V)
