What is PCB? What is FPC? Difference between FPC and PCB

PCB is called printed circuit board, is the carrier of electronic components. pcb stackup calculator The full name of FPC is flexible printed circuit, that is, flexible printed circuit board. Similar to PCB, FPC is also the carrier of electronic components. Although both are circuit boards, they have their own unique application scenarios and characteristics.

1. What is PCB

A PCB is a circuit board that prints conductive material on an insulating board, holes holes on it, and then chemically etches away excess conductive material. 1 oz vs 2 oz PCB is widely used in electronic products, such as mobile phones, computers, televisions, etc., is an indispensable part of modern electronic products.

2. What is FPC

Compared with rigid PCBS, FPC has better flexibility and bending properties, so it is suitable for equipment with high space requirements. The manufacturing process of FPC is similar to that of PCB, but the substrate used is generally a flexible polyimide (PI) film, which can be rolled and folded to achieve different shapes. FPC is widely used in notebook computer screens, mobile phone touch screens and other areas that require flexible circuit boards.

3. Difference between FPC and PCB

Compared with PCB, FPC has obvious advantages and differences in terms of flexibility, size, weight and number of connectors. Generally speaking, due to its thin and flexible, easy to physical damage, not suitable for bearing heavy loads and other characteristics, flexible concrete needs to consider its tear resistance and compressive resistance. PCBS are relatively rigid and are usually used to fix equipment and emphasize dimensional accuracy. In addition, due to different production processes, the cost of FPC is higher than that of PCB.
