The Role Of PCB Stiffener In PCBA Processing

What are PCB stiffeners?

PCB stiffeners play an important role in providing mechanical support for PCB. They play an important role for flexible circuit board PCBA processing when stiffness is required in certain areas.
PCB stiffeners are especially needed when components are placed in flexible areas where the weight of these components can put pressure on the flexible material. They can also be used to create a rigid PCB surface to place components and solder in SMT processing. In addition, connectors that require multiple insertions require PCB stiffeners to reduce the stress on the PCB pads. Let’s look at the uses of PCB stiffeners in more detail.



1、Various uses of PCB stiffeners?

Simply put, PCB stiffeners are used where a certain area of the circuit needs to be hardened. Some common reasons for using stiffeners in PCBA processing:
1. Circuit board support area with SMT or SMD component PTH components.
2. Maintain a reasonable thickness of the flex circuit.
3. Support PCB connector.
4. Make sure the board is better handled.
5. Make sure the board area is stable.
6. Helps route and reserve the array.
7. Helps to relieve stress and effectively dissipate heat.


2、 Broadly speaking, flexible PCB (FPC) stiffeners are required to fall into the following usage categories:
1. Rigid component/connector area
2. ZIF (Zero Insertion Force) Thickness Requirements
3. Local Bending Constraints


3. Component/connector stiffeners
They essentially create a rigid area connected to the area. They also protect the solder joints to ensure flexibility in the component area without bending.


4. ZIF stiffeners
They ensure increased thickness at the contact fingers to meet specific ZIF connector specifications.


5. Local Bending Constraints
They confine the bending area to a specific location in the flexible design.
