Why Manufacturing ITEQ IT-189 PCB the Delivery Time is long and Price Expensive?

The manufacturing of ITEQ IT-189 PCBs often involves a longer delivery time and higher costs due to several factors. First, the high TG (glass transition temperature) materials used in ITEQ IT-189 PCBs are designed to withstand elevated temperatures, making them ideal for applications with demanding thermal requirements. The production process for these specialized materials may be more complex and time-consuming, contributing to longer lead times.

Additionally, the advanced properties of ITEQ IT-189 materials, such as enhanced thermal performance and reliability, require stringent manufacturing processes and quality control measures. This can further extend the production timeline and add to the overall cost of manufacturing.

Furthermore, the demand for high-performance PCB materials like ITEQ IT-189 may also impact pricing and lead times. These materials are often sought after for critical applications in industries such as aerospace, automotive, and telecommunications, leading to a premium on both cost and delivery schedules.

Despite the longer lead times and higher costs associated with ITEQ IT-189 PCB production, the benefits of its high TG properties and exceptional performance make it a valuable choice for applications that require reliability and durability in challenging environments.

Compare with Other High TG PCB Materials

When comparing ITEQ IT-189 High TG PCB materials with other high TG materials, it’s important to consider factors such as glass transition temperature, mechanical properties, electrical performance, and cost. Here’s a comparison with some commonly used high TG PCB materials:
