Benefits of Flexible PCB
In past few years, PCB design engineers tended to considerations and best practices for rigid PCB. But with the development of emerging Internet of things and intelligent wearable products, flexible PCB design skills quickly become a prerequisite for engineers.
The most basic application of flexible PCBs is to provide a flexible alternative to traditional wires. Its flexible property makes it ideal for industrial sensor technology. Flexible PCB design method is very different from the traditional one. Here are some important points for your reference.
As to space saving and bending ability, flexible PCB is preferred. However, designers need to be aware of the possibility of cracked solder joint when the circuit is bent. This requires the combination of arc and fillet pads in flexible PCB design.
Cross-Hatched Ground Plane
In rigid PCB designs, it is preferred to pour a solid ground plane. However, cross-hatched ground plane may be preferred when designing a flexible PCB, because it can improve circuit flexibility while providing effective shielding.
If you want an electronic product to operate reliably in a high temperature environment, using a flexible PCB may be the right choice. It is effective in heat dissipation and can function at temperature up to 400°C, which is ideal for the oil and gas industry.
Flexible PCBs generally have greater minimum trace width than rigid PCB board. It is common for suppliers to specify a minimum 0.010″ trace width. However, as the manufacturing capacity increases, the minimum trace size is gradually decreasing. You may need to consult your supplier for the correct specifications.
