What is Flexible PCB?

Flexible circuits (also variously referred to around the globe as flex circuits, flexible printed circuit boards, flex print, Flexi-circuits) are members of electronic and interconnection family.

They consist of a thin insulating polymer film having conductive circuit patterns affixed thereto and typically supplied with a thin polymer coating to protect the conductor circuits.

The technology has been used for interconnecting electronic devices since the 1950s in one form or another.

It is now one of the most important interconnection technologies in use for the manufacture of many of today's most advanced electronic products.

High Temperature and High-Density Applications:

In many cases, flex circuits are made of polyimide 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 impedances in high-density circuit board designs, flexible circuit designs offer many benefits to manufacturers.

What are the differences between the Poyester (PET) and Polymide(PI) material?

The flex pcb raw material and stack up will decide the flex circuit quality.

According to the market demand, there are three types of base raw material used for Flexible circuit board. Poyester(PET), adhesive Polymide (PI) and adhesiveless Polymide (PI) .

Do you know the difference between the PET and PI material?

If not, let us learn about it together now.

The advantages and disadvantages of Polyester(PET) and Polymide(PI).

The advantages of PET material: Production process is less, price is cheaper, lead time is shorter.

The disadvantages of PET material: Polyester material can not pass through soldering flow. Then it can not be working in high temperature environment.

The advantages of polymide (PI): It’s easy to bend. Can work in high temperature.

The disadvantages of Polymide (PI): The price of raw material is much higher than Polymide.

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.

YScircuit creates both flexible and printed circuit boards for product manufacturers.
