Flex circuits are now in high demand, and it seems that this trend will continue to grow. Why are flexible PCBs so desirable and indispensable for the Internet of Medical Things (IoMT)? In the evolution of electronics, flexible PCBs have enabled many medical and laboratory devices to become smaller, smarter and lighter. Bearing the exact same request came one of our customers, specializing in quality control instrumentation for specific laboratories. What was the recipe for the fast and successful completion of a flexible printed circuit board assembly (PCBA) prototype for medical laboratory use? Read our case study to find out!
What is a flexible PCB?
The printed circuit board is the foundation for the construction of electronic devices. But the more complex the project becomes, the greater the difficulty in achieving the ideal PCB for an electronic product. Let's then take a closer look at the main definitions of a PCB.
Initially, PCB manufacturers made simple circuits as single or no more than two-layer PCBs. Since then, the production method has evolved until now it allows the creation of complex, multilayer printed circuit boards and rigid-flexible PCBs.
A flexible PCB begins by drawing conductive paths onto a dielectric substrate. Each board contains flexible laminates made of special materials to ensure the flexibility of the finished board. These types of laminate primarily rely on a thin polyimide (PI) film as a substrate to protect the board from high temperatures. The resulting flexible printed circuits can easily fit into any shape of electronic device without any loss of its properties.
