Why we should use, flexible PCB apply in Radar systems?
First of all, must be clear that here we discuss flexible PCB apply in radar system.
In fact, in most radar products, also use the PCB type, like rigid PCB, multilayer PCB board.
So we will discuss the flexible PCB part in radar systems.
Usually the radar system has big dimension, also have require flexible function.
This means we should choose flexible PCB in this area.
Three basic benefits of flexible PCB in radar applications
The interconnect cost saving
You know all radar systems have complex construction and functions.
And require good electronic ability and performance PCB boards.
If you use a metal core PCB in a radar product, most of the time the thickness may up to limited.
The flexible PCB can meet those requirements, good performance and saving interconnect cost.
The simplified assembly steps
If you have visited PCB assembly factory, you may know the assembly process can be differentiated.
In some advances flexible PCB factories, most to assembly steps can be automatic.
This means the radar system assembly process can be simplified.
The perfect RF ability
The RF ability is very important for radar system products.
Image that The RF connect poor, when use a CEM 1 PCB.
Radar engineers consider the RF ability, use a flexible PCB is the best choice.
How a flexible PCB engineer understands radar application?
Most of flexible PCB engineers consider shielded factors in radar case.
You know flexible PCB can provide EMI and RFI shielding ability.
If you have some electronic knowledge, you can be known that most of CEM1 PCB can not have those abilities.
Then there were multiple option to meet flexible PCB EMI ability.
Multiple options including sliver ink, copper layers, and EMI shielding films.
