Rigid and flexible printed circuit boards (PCBAs) are used in a wide variety of different fields, including: digital computer, communications, aerospace, and home equipment industries. From the name we can distinguish the two,FS rigid PCBA refers to the circuit board built on the base layer that is not bendable. At the same time FS Technology flexible PCBA (also known as FPC, soft board). This type of circuit board has the characteristics of excessive wiring density, light weight, thin skin, and is very reliable constructed on the basis of bending, capable of bending, twisting and folding.
While each traditional FS Tech rigid PCBA and bendable FPCB serve equally simple purposes, it is critical to observe that there are many variations between them. Flex circuits are not just curved PCBs, they may be composite, which differs from rigid PCBAs in many characteristics. Get an overview of the properties of inflexible and bendable PCBAs below.
What is the difference between rigid PCB and flexible FPC?
An inflexible PCBA is usually referred to as a PCBA without emphasizing that it is a rigid PCB. It's people who think about all kinds of different things when they think about a circuit board. These various discussions will determine what type of PCB you buy from FS Technology. In rigid PCBs, the non-conductive substrate typically includes a glass fabric that reinforces the circuit board and provides it with power and stiffness. Our discussion of rigid PCBAs revolves more around their thermal resistance characteristics.
Although flexible flexible circuit boards also have wires on non-conductive substrates, such boards use flexible substrates including polyimide (PI). The curved base allows FS Technology's FPC to withstand vibrations, dissipate heat and fold into different shapes. Due to their structural advantages, flex circuits are increasingly used as a replacement for compact gadgets, including smart wearables, cell phones, and cameras.
Aside from the underlying fabric and pressure, the big differences between FS Technology rigid PCBs and flex circuits include:
1. Conductive fabric: Since flex circuits are supposed to bend, manufacturers can also use softer rolled annealed copper instead of conductive copper.
2. Manufacturing System: Flexible PCBA producers do not use solder mask, but use a system called a coverlay or overlay to protect the uncovered circuit photos of the flexible PCB.
3. Typical costs: Flex circuits are generally more expensive than rigid circuits. However, since flexible circuit boards may be connected in tight spaces, engineers can downsize their products, saving overhead.
How to choose between rigid and flexible PCBs
Rigid and bendy FPCs are used in lots of one-of-a-kind merchandise, even though a few programs can also additionally advantage extra from one kind of circuit board. For example, inflexible PCBs make feel in large merchandise together with domestic home equipment and computers, even as extra compact merchandise together with smartphones and wearable era require bendy FPCs.
When choosing between rigid PCBs and flexible FPCs for your electronics project, consider your application needs, industry-preferred board types, and purchase the required circuit boards from the FS Technology website.
