Consider your rigid flex PCB at its Reliability & Durability
There were many articles about rigid flex PCB advantages.
Even some of them compare with metal core PCB, says rigid flex PCB is better than MCPCB.
We don’t want to comment this view on the web, due to usually two types have each own application.
Differ applications require different electronic connect ability.
Today 4MCPCB engineers will introduce rigid flex PCB’s reliability and durability.
#1 Rigid flex PCB can eliminating interface connections
You know the interface connection ability is the main ability to measure multilayer PCB’s.
And the conventional multilayer PCB board connects ability depend on the interface connects ability.
The interface connection ability includes solder joints, connectors and contact crimps etc.
If you have understood the rigid flex PCB design, you will know there were few interface connections.
This mean rigid flex PCB can eliminating interface connections.
#2 Rigid flex PCB can design fewer number interconnects
If you have asked some rigid flex PCB designers, you will be knowing that the rigid flex PCB can be design fewer number interconnects.
But why designers want to fewer interconnects, and how can they do that.
The first, as we know the fewer number of interconnects, the fewer the sources of potential failure.
That’s the main reason designers and electronic engineer want fewer interconnect rigid flex PCB board.
Then rigid flex PCB is a complex process, due to it integrates both a flex circuit and a rigid PCB technology.
This means we can further reduce the number of interconnects.
#3 Rigid flex PCB can improve electronic performance
As we know the flex PCB part were made by the PI, and provide good bending ability.
In other words, rigid flex PCB also has good bending ability.
4MCPCB experts told us, flex PCB part have good ductility and reduce the impact of vibration and shock.
This is the reason why rigid flex PCB can improve electronic performance.
#4 Rigid flex PCB also has good heat management ability
We have mention flexible PCB part have used a material named PI.
In fact, PI is short for Polyimide, and has exceptional thermal stability.
So, rigid flex PCB can be withstand applications with extreme heat.
If you have comparatively with other traditional multilayer PCB board, you will find the rigid flex PCB has a better base for surface mounting.
All of the heat management due to its excellent thermal stability.
By the way, the compliant base film places less stress on soldered joints, thermal mismatch is less likely to occur.
