Uniwell Circuits Co., Ltd has a professional technical team with 10 years of experience in PCB manufacturing, constantly enhance the level of PCB technology and production capacity. As a PCB supplier, Uniwell is not only offering one-stop service as PCB design, PCB production, and PCB Assembly, but also taking great advantages on prompt delivery time and competitive price with no quality compromise.


2.Production process

It's simple for the production process of rigidized flex construction, just bonding stiffeners for flexible circuit. While rigid-flex PCB is comparatively complex, they need many times laminations. When fabricating rigid flex PCBs, the factory need both rigid PCB production machines and flex PCB production machines.The quality control will be more difficult.

3.application
Nowadays, rigid flex circuits are usually used in high-end electrical applications, and most are prototypes, few volumn production, such as satellite,medical devices,military,communications equipment.Rigidized flex construction are more widely used in mobile phones, laptops, sensors.

5.little knowledge---the history of flexible circuit board
FPC(Flexible printed circuit) refers to a thin insulating polymer film having conductive circuit patterns affixed there to and typically supplied with a thin polymer coating to protect the conductor circuits.While rigidized flex construction actually is also flexible printed circuit but it's bonded with FR4 stiffener to strengthen the rigidity when assembly.So by nature rigidized flex construction is still flex circuit. 


Flexible electronics, also known as flex circuits, is a technology for assembling electronic circuits by mounting electronic devices on flexible plastic substrates, such as polyimide, PEEK or transparent conductive polyester[1] film. Additionally, flex circuits can be screen printed silver circuits on polyester. Flexible electronic assemblies may be manufactured using identical components used for rigid printed circuit boards, allowing the board to conform to a desired shape, or to flex during its use. An alternative approach to flexible electronics suggests various etching techniques to thin down the traditional silicon substrate to few tens of micrometers to gain reasonable flexibility, referred to as flexible silicon (~ 5 mm bending radius)
