What are the components of FPC processing costs?

While the printed circuit board industry employs some common basic processes, the most crucial aspect is determining different production processes and equipment based on substrate thickness and material, precision requirements for line width and spacing, design structure, production scale, and other specific customer requirements. This leads to significant cost variations in FPC production. FPCs are highly customized products, with numerous cost components. For novice purchasers in electronics factories, it's essential to understand the cost components of FPC flexible circuit boards before prototyping.

The production process for FPC flexible circuit boards is complex, typically involving over 40 processes, including inner layer production, exposure, lamination, drilling, and electroplating. Taking FPCs as an example, typical processes include exposure, development, etching, copper plating, and stripping. Although FPCs are highly customized, these basic processes are essential, with differences only in specific parameters. Each process in FPC production is relatively mature; therefore, cost control becomes the key differentiator in profitability among FPC flexible circuit board manufacturers. Cost control is reflected in all aspects of the flexible circuit board manufacturer's operations, directly depending on the company's management level and requiring attention to detail. BNY is a "specialized, refined, and new" manufacturer specializing in high-precision, multilayer PCBs, special processes/materials, and special PCBs, providing rapid prototyping and small to large batch services, focusing on PCBs others cannot handle.

In the cost structure of FPC flexible circuit boards, direct material costs typically account for around 60%, direct labor costs for around 15%, and manufacturing overhead for around 25%. However, copper-clad laminate suppliers hold significant power, so FPC manufacturers primarily reduce costs by lowering manufacturing and labor costs. Manufacturing cost reduction is mainly achieved through automation to improve production efficiency and yield, while labor cost reduction is achieved through relocation to central and western regions.
In summary, when prototyping FPC flexible circuit boards, fewer quantities do not necessarily mean lower prices; the unit price may be higher. For prototypes, the factory needs to prepare engineering documents, films, and conduct testing; production processes do not reduce costs with smaller quantities. FPC manufacturers consider many factors when quoting prices; for details, please refer to the cost factors of FPC circuit boards. The cost of FPC flexible circuit boards depends on many factors. Past experience indicates that higher FPC quality requirements lead to higher costs.
