The electronics industry is witnessing a new wave of change. A number of miniaturized products are now available. Many commercial products are being designed to be worn by the user. At the same time, there is a demand for better speeds, and small packaging densities. All these aspects have to be taken into consideration by flex PCB manufacturers during PCB assembly.
A Brief Look at one Application Industry
Let us take the example of the medical device market. This is one of the fast growing markets in the world. In this industry, you have equipment such as wireless healthcare units, and remote patient monitoring systems. Many of the devices used by doctors or patients are now wearable. These devices require miniature components, thinner materials, and custom circuit geometries.
For such requirements, the standard 1 ounce copper will not be equitable. With the reduction in densities, PCBs will need to be constructed with materials between 9 and 12 microns.
Flexible printed circuit boards are the answer to this new requirement. Flex circuits can be designed in small sizes, thus assisting in the product miniaturization process. They can be designed in almost any thickness level, depending on the manufacturing materials. They are not limited by the standard PCB thickness ranging from .031 to .062ʺ.
They can create strong interconnections, while supporting assembly and packaging processes. Overall, they provide a dynamic electro-mechanical solution. Flex PCBs are particularly useful for PCB assembly processes. They can be configured with repeatable conductors that ensure no errors in the assembly process.
These various points are the reasons behind the continual popularity of Flex PCBs. The points justify manufacturers choosing flex circuits rather than rigid PCB designs. With more custom flex designs being created by manufacturers, the new wave of electronics components will be extremely successful.
