　　The cost of flexible PCBs can vary significantly depending on multiple aspects, making it essential to understand the main drivers behind pricing. These factors include material selection, production complexity, order volume, and even the supplier¨s location.

　　

　　Material Selection and Its Impact on Price

　　

　　One of the most crucial factors in determining the price of a flexible PCB is the type of material used. Flexible PCBs typically use polyimide or polyester substrates, with polyimide being more expensive due to its superior thermal stability and flexibility.

　　

　　Polyimide (PI): More expensive but offers excellent heat resistance and mechanical properties. Ideal for high-performance applications in aerospace or automotive sectors.

　　

　　Polyester (PET): Less expensive, mainly used in cost-sensitive applications where extreme heat resistance is not required.

　　

　　Conductive materials like copper can also affect costs. Thicker copper layers offer better performance but come at a higher price. The choice of adhesive or overlay materials can further add to the final cost.

　　

　　Manufacturing Process and Complexity

　　

　　The complexity of the design directly impacts the price of flexible PCBs. Multilayer boards, rigid-flex designs, or intricate patterns require more time, expertise, and advanced machinery to manufacture, which increases costs. Single-layer PCBs, by contrast, are relatively simple to produce and thus less expensive.

　　

　　Key factors that affect manufacturing costs include:

　　

　　Number of layers: More layers add complexity and cost.

According to Agence France-Presse reported on May 22, the U.S. health authorities announced on the 22nd that another case of human infection with avian influenza occurred in the United States. The case is related to the spread of the avian influenza virus among dairy cows.

The U.S. Centers for Disease Control and Prevention (CDC) said the infected person was working on a farm in Michigan where cows were infected with the H5N1 virus.

However, the CDC said that the current risk assessment of avian influenza to the American public is still low.

On April 1, the United States state of Texas announced a human case of avian influenza. The CDC said this is likely to be the world’s first case of avian influenza infection through cows.

The CDC noted that people infected in Michigan, like people infected in Texas, only develop symptoms in the eyes. Both have now recovered.

Reported that although human cases of infection with the disease are still rare, experts are concerned about the increasing number of mammals infected with the disease.

There is currently no evidence that the virus spreads from person to person, but scientists worry that the massive spread of the virus may cause the virus to mutate, allowing it to spread from person to person. (Compiled by Lin Xiaoxuan)
