What is High CTI PCB?

High voltage PCBs are custom designed PCBs withstanding high voltages and high power in severe environments. CTI (Comparative Tracking Index) is an important rating that reflects the level of electrical tracking on the surface of the insulating material. High CTI means that the material can withstand a higher level of electrical arcing and breaking down the insulation material, so high CTI PCB can be applied to high safe and reliable demanded application. As a professional High CTI PCB manufacturer, we are capable to provide long life and high quality products for your special needs in automotive, industrial, power electronics and more industries.

What does CTI mean in PCBs?

CTI is an indicator to tell us a material can prevent electrical track or not, which is a phenomenon involving the flow of current on the surface of insulating materials caused by contaminants (like dust, humidity and chemicals). The CTI value is given in volts and can be divided into different classes where materials with a high CTI value mean generally greater than 600V. High CTI PCBs employs materials with strong insulation that lessens the possibility for short circuits, harm to the components or system malfunctions that is produced by electrical tracking. These PCBs are critical, especially in HV (high voltage) situations. 

Key Features of High CTI PCBs

They have the following advantages which allow them to be a must have for critical application:
Increased Safety: Better insulated due to the high CTI value results in less chance of electrical arcing, which leads to safer system.
Robustness: Such PCBs are made for use in the vulnerable environment of moisture, dust, chemical, etc.
High Voltage Withstand: High CTI materials enable the PCB to be exposed to high voltage without affecting its performance.
Improved Reliability: They also deliver long-based reliability as they reduce the chance of electrical tracking in mission critical applications of high CTI PCBs. A high-quality manufacturer of High CTI PCBs with more than 15 years of experience in the OEM industry, we know how significant these are in quality assurance regimes and craft our designs to exceed industry accepted standards. How Are High CTI PCBs Manufactured? To make high CTI PCBs, high quality materials and precision process are required. 

High CTI PCB Main Steps

Material selection
The insulating material is the platform of a high CTI PCB. High CTI value materials such as FR-4 or special composites are available to provide outstanding resistance to electrical tracking. We are a reputable manufacturer of High CTI PCBs and therefore we scrupulously choose high quality materials that are compatible with your application. 

PCB Design and Layout 
The design stage is essential for achieving good results. High CTI PCBs may also necessitate increased distance between conductive traces to avoid arcing, particularly at high voltages. Our engineers employ state of the art design software to develop layouts that optimize safety and productivity.

Laminating and Layering up
High CTI PCBs can be multilayer to support intricate layout. The lamination procedure has to be so executed as to the high CTI property of the material could be brought out in a sufficient bonding and lining up of the layers.

Drilling and Plating
Holes and vias are drilled with high precision. The plating process provides a consistent, durable electrical conductive layer while maintaining the insulating properties of the PCB.

Surface Finishing
Surface finishes such as HASL (Hot Air Solder Leveling), ENIG (Electroless Nickel Immersion Gold) and OSP (Organic Solderability Preservative) are used to protect the PCB and increase its longevity.

Testing and Quality Control
All high CTI PCB is tested strictly to ensure its performance and safety. This includes electrical testing, insulation resistance testing, and environmental stress testing. As a Top High CTI PCB manufacturer you can trust, we are keen on quality control to ensure delivery of flawless products.
