The IoT is discussed so much that it gets about 2.5 billion clicks on a Google search. More and more electronic companies wants to know this area development, which touches our lives in so many ways nowadays as internet connection becomes increasingly incorporate into everyday objects and physical phenomenon.
Electronic devices are proliferating and diversifying as the rapid growth of Internet of things (IoT) market, and they need to reduce the time it takes to get the product to market is more important than any time if electronics companies want to stay enough competitive.
Putting these products into practice depends on PCB, but it can be the toughest jobs. How do we integrate advanced features into our ever-shrinking products?
Big Challenging for Layout Space
With ever shrinking packages means there is going to be a competitive fight for layout spaces. IoT devices will need to be jam packed with functionality, all of IoT devices will need to be integrated into something that can be wearable or even potentially something that could be ingested.
SO PCB Size is very importance,how can we choose it?To achieve this tight functionality and flexibility, you may find that a combination of rigid-flexible and high-density interconnect (HDI) PCB design is required.
Rigid-flexible PCB offer the flexibility to use multiple PCB in tight spaces. Moreover, HDI allows for denser component placement and the use of blind, hidden and micro-vertical interconnect access – HDI is extremely valuable when trying to save board space.
Rigid-flexible PCBS have the advantage of flexibility, allowing multiple PCBS to be used in a narrow space. Moreover, the HDI allows for dense-component placement and the use of blind, hidden, and micro-vertical interconnected-HDI is invaluable when trying to save space on the board.
There are several types of flexible PCB, more commonly flex, rigid-flex and high-density-
interconnect (HDI) flex board.
These are flexible versions of the widely used rigid PCB. Rigid PCBs offer the usual reliability, repeatability and high density for extra flexibility and vibration resistance.
As the name implies, this type of PCB provides a combination of rigidity and flexibility, which has the best in the world, while adding some other features that are not unique.
A typical rigid-flexible structure is a series of rigid PCBs connected by integrated flexible circuits. This combination gives designers a variety of options for creating solutions for the most demanding IoT applications.
HDI flexible PCB
If a typical flexible circuit is not suitable, it may be necessary to turn to a high density interconnected PCB. HDI Flex PCB offer improved design, layout and construction options through integrated microvia and more.
Although HDI technology uses thinner materials, it also provides better reliability, enhanced electrical performance, and the ability to use advanced IC packages.
Not only the choice of materials, PCB designers need to solve the IOT problem based on more comprehensive factors.
