What is Flexible PCB

General Introduction of Flexible PCB

Flexible circuit board, also known as "soft board", commonly known as FPC board, is a printed circuit made of flexible insulating substrate. Flexible circuit board can greatly reduce the volume and weight of electronic products, suitable for electronic products to high-density, miniaturization, high reliability direction development needs. Therefore, FPC board has been widely used in aerospace, military, mobile communications, laptops, computer peripherals, PDA, digital cameras and other fields or products.

High Temperature and High-Density Applications:

In many cases, flex circuits are made of polypeptide or a similar polymer. This material dissipates heat better than most rigid circuit board materials. For this reason, flexible circuits can be placed in inconvenient locations where heat would impact the performance of a rigid circuit board.

Flexible circuit boards can be designed to withstand extreme temperatures – between -200° C and 400° C – which explains why they are so desirable for borehole measurements in the oil and gas industry.

In fact, because of these conditions, and the need for small, unobtrusive devices in most industrial environments, flexible circuits represent the first choice for engineering design in most industrial sensor technologies.

High-temperature resistance comes usually comes with good chemical resistance and excellent resistance to radiation and UV exposure as well. Combined with the ability to control impedance in high-density circuit board designs, flexible circuit designs offer many benefits to manufacturers.

Why Not Make All Circuit Boards Flexible?

Flexible circuit boards are certainly useful, but they are not going to replace rigid circuit boards for all applications. Cost efficiency is the main obstacle to implementing an exclusively flexible circuit board design in a consumer product. Rigid circuit boards are less expensive to manufacture and install in a typical automated high-volume fabricating facility.

Typically, the ideal solution for an innovative product is one that incorporates flexible circuitry when necessary and employs solid, reliable rigid circuit boards where possible to keep manufacturing and assembly costs down.

Some manufacturers even use hybrid rigid-flex printed circuit boards expressly for this purpose. This is common in laptop computers and medical devices, where rigid circuit boards can be connected to one other using ribbon-like flexible circuits. These boards can be compounded and designed to meet any number of engineering needs by focusing on the respective strengths of each circuit board base technology.
