Five common mistakes in the use of flexible Circuit technology

The main problem with the use of flexible circuits underestimated what is involved in a successful start program. Too often supply chain teams deal with flex give the process as a commodity, little time and attention. The result is usually poor quality, higher start-up costs and delayed product introduction.

The following are five common mistakes companies make when starting a project using flexible circuits.
Not doing due diligence with supplier selection: there are many flexible PCB suppliers to choose from, each with unique opportunities and problems. Assuming that "each vendor" may be enough to meet your needs, or basing your selection strictly on price is a recipe for disappointment.
Not your dealer in the design process: There are a lot of nuances in the production of a flexcircuit; the fact that it is flexible adds challenges for design that face a hard board does not. Your dealer can help with designing a product that is more reliable, easier to build and ultimately more profitable. Forcing your supplier to build to print can lead to more quality issues, poor on-time delivery and a less reliable product.
Using PCB CAD software for designing a flex: This problem is related to the previous point, but PCB software does not prevent common production and quality design issues that are unique to a flexible circuit. Sharp corners, solder fillets near bend points, not cater to material stability problems are just some of the issues that standard PCB design software.
Compressed timelines: The flex is often the last element in the electronic package. When the product team finally gets around to grab the flex circuit, they are already behind schedule. Such pressure can force shortcuts. The result is a poorly designed product that many production and reliability issues for the duration of the product will have. In addition, you will be forced to pay for premium quick turn production.
To believe that Flex has no restrictions: flexible Circuits in dynamic flex applications that go beyond can operate millions of cycles. Sometimes a circuit to assume that it is indestructible. Other elements, such as mechanical wear, sharp bend RADIUS and turning can lead to premature failure. An expert vendor you can aware of any limitations of the long term to create an application.

Flexible Circuits are often the most cost effective means of electronic packaging interconnection. They offer a range of benefits of sustainability, weight and design features. The above errors can go a long way in ensuring a successful product launch.
