What is FPC in High Frequency PCB? |
|
|
|
| |
|
1. Overview of FPC |
|
|
|
| |
|
Flexible Printed Circuit Boards (FPCs), or "soft boards," are made from flexible substrates like polyimide, offering bendable, coilable, and foldable designs. They reduce product size and weight, enabling high-density, miniaturized, and reliable electronics. Widely used in aerospace, military, communications, and consumer electronics, FPCs provide unmatched flexibility and performance.
The functions of flexible circuit boards can be categorized into four types: lead lines, printed circuits, connectors, and multifunction integrated systems. These functions are utilized in a wide range of areas, covering computers, computer peripheral auxiliary systems, consumer household appliances, and automobiles. |

2. Key Benefits of FPC |
|
|
| |
|
2.1 Excellent heat dissipation:
Ensures reliable performance in high-temperature environments.
2.2 Good solderability and ease of mounting:
Simplifies assembly processes and reduces production time.
2.3 Cost-effective:
Provides a budget-friendly solution for complex electronic designs. |

3. Configurations and Materials |
|
|
| |
|
Flexible Printed Circuit Boards are available in single-layer, double-layer, and multi-layer configurations, with the base material being polyimide clad laminate, renowned for its high heat resistance and excellent dimensional stability. Coated with a protective film for mechanical protection and electrical insulation, FPCs ensure durability and reliable performance. In double-sided and multi-layer designs, metallized conductors seamlessly connect inner and outer layers, enabling efficient electrical performance for complex applications. |

4.General Description of Shengyi SF201 FPC |
|
|
| |
|
Speaking of the Flexible Printed Circuit Board, SF201 FPC springs to my mind.
Let's elaborate on this with Shengyi SF201 Polyimide serving as an example.
This flexible printed circuit is designed for Bluetooth headset applications. It is a single-layer FPC constructed on 0.15mm thick SF201 adhesiveless polyimide laminate. Fabricated in compliance with IPC 6012 Class 2 standards using provided Gerber data, it features a polyimide stiffener on the inserting part for enhanced durability and performance. |
