Production Flow of Flex-Rigid PCB and Its Advantages & Disadvantages

What is a Flex-rigid PCB?


The birth and development of FPC and PCB gave birth to the new product of flexible and rigid printed circuit board.


Flexible and Rigid Printed Circuit Board


Soft and hard bonding plate is the flexible circuit board and hard circuit board through the compaction and other processes, according to the relevant process requirements combined to form a FPC characteristics and PCB characteristics of the circuit board.


Production Flow:

Because the soft and hard bonding plate is a combination of flex pcb and PCB, the production of soft and hard bonding plate should have both FPC production equipment and PCB production equipment.


1. Electronic engineers draw the trace and layout of the soft bonding plate according to requirements.

2. Issued to the production of Flex-rigid PCB board factory, after the CAM engineer dealing and planning with the relevant documents, then arrange the FPC production line to produce the required FPC, PCB production line to produce PCB, these two soft board and hard plate out after that,in accordance with the planning requirements of electronic engineers, the FPC and PCB through the compressor seamless compaction.


3. After a series of detailed links, the final process of the soft and hard bonding board.


One of the most important part, is the Test of flex-rigid PCB board , There are many details need to be confirmed before shipping, generally have to carry out a full inspection, so as not to allow both supply and demand to cause the loss of related benefits, so the value is relatively high.

Advantages & Disadvantages:


Advantages: Soft and hard bonding plate at the same time has the characteristics of FPC and PCB characteristics, therefore, it can be used in some products with special requirements, both a certain flexible area, but also a certain number of rigid areas, to save the interior space of products, reduce the volume of finished products, improve product performance has a great help.


Disadvantages: The production process of Flex-rigid PCB boards are numerous, the production is difficult, the yield is low, the pcb materials and manpower wasted  more. Therefore, the price is relatively expensive and the production cycle is relatively long.
