1. **FPCB Purpose and Method of Use**
The FPC cable is defined on the website as a group of connecting wires that can be bent to a certain degree. Its base material is typically made of rolled copper, known for its flexibility and resistance to twisting. Additionally, it serves as a functional form of FPC. With that said, the following content will discuss the advantages and disadvantages of FPC.
2. **FPCB Advantages**
Let’s start with its advantages. The use of FPC can significantly reduce the size and weight of electronic products, making it ideal for the development of devices that prioritize high density, miniaturization, and reliability. Therefore,
FPC has found extensive applications in aerospace, military, mobile communications, laptops, computer peripherals, PDAs, digital cameras, and various other fields or products. Additionally, it can be arranged flexibly to meet spatial layout requirements, enabling movement and expansion in three-dimensional space, which facilitates the integration of component assembly and wire connections.
**Shortcomings**
When producing products, cost is often the most critical factor to consider. Since flexible FPC is designed and manufactured for specific applications, the initial circuit design, wiring, and photomask creation entail higher costs. Unless there is a compelling reason to use soft FPC, it is typically advisable to avoid it for small-scale applications. Moreover, given the substantial investment in production, post-maintenance becomes essential, meaning that soldering and rework must be performed by trained personnel.
**How to Store FPC Cables**
Unlike other products, FPC flexible circuit boards should not be exposed to air and water. So, how should we properly store this product? The answer will become clear after reviewing the following guidelines.
First, the vacuum integrity of the FPC flexible circuit board must be preserved. During packing, bubble wrap should be placed inside the box. The bubble wrap has superior moisture-absorbing properties, effectively preventing humidity. Moisture-proof beads are also essential.
Second, once sealed, the box should be stored in a dry, ventilated area on partitioned shelves and off the ground, avoiding direct sunlight. The ideal warehouse temperature is around 23±3 degrees Celsius with a humidity level of 55±10% RH. Under these conditions, PCBs with surface treatments such as immersion gold, electro-gold, spray tin, and silver plating can generally be stored for up to 6 months. Surface-treated PCBs, such as those with Shen tin and OSP, are typically suitable for storage for about 3 months.
After the final inspection of the finished product, FPC flexible circuit boards can be vacuum packaged and prepared for shipment. Why is vacuum packaging necessary for flexible circuit boards? What are the best practices for storage post-packaging, and what is the expected shelf life? After reading the above content, these questions should be clearer.
In summary, the advantages and disadvantages of FPC cables are evident, making it easier to understand how to store FPC cables effectively.
