Some new features of flexible printed circuit board

We have discussed rigid flex PCBs, and have introduce for the common sense of the rigid flex PCB.
Similar to rigid flex PCB, flex printed circuit board (flex PCB) also has those advantages.
But not only that, flex PCB has more features to be chosen.
Let met to begin to introduce some features of flex PCB.

Flex PCB has high density feature

First of all we should better here we discuss high density was not similar HDI PCB.
If you have read our article about HDI PCB stack up, you may know hole design is most complex.
The high density of flex PCB to support new products small packaging needs.
You know most of current new products, there were require a small space for driving forces in functional density and size reduction.

Flex PCB has the extremely thin feature

If you have a look a piece of flexible PCB, you can easily know its extremely thin feature.
A circuit board which reduces the bias force with a thin base pill to combine improved flexibility with double-sided micro line processing.

Flex PCB has a high thermal transfer feature

Some may say there were so few products use high thermal feature.
Yes, not all electronic products need not require the high thermal ability, and most consumer goods also need not require that.
In some special application, the high thermal transfer feature is the key factor.
For example, the medical industry might use a heater circuit to keep a solution warm during analysis;
A handheld device might need a heater on the back of the LCD to keep it working in all conditions;
A high-end inkjet printed might need a heater circuit bonded to the reservoir to keep the ink flowing.

Flex PCB has an exceptional heat resistance feature

You may strange by this title flex PCB has exceptional heat resistance.
Yes, usually flex PCB did have good heat resistance.
Emma just discuss in some special application of the flex PCB board.

The most highly heat resistant FPC has reached 150℃ and the maximum temperature reach 175℃.
The exceptional heat resistance, flex PCB designer told Emma that by enhancing the heat resistance of the adhesive layer of the insulation film (coverlay) to withstand high temperatures of 100℃ or over.
This mean during the normal application, the coverlay layer can not withstand so high temperature.
