The Rigid Flex PCB Board is a new type of printed circuit board that combines the durability of a rigid PCB and the adaptability of a flexible PCB. in all types of PCB, rigid and flexible combination is the most resistant of the bad application environment,therefore the industrial control, medical and military equipment manufacturers,the mainland enterprise is also gradually improve the Rigid Flex PCB accounted for the proportion of output as a whole.
1. What is the Rigid Flex PCB Boards?
The birth and development of FPC and PCB gave birth to the new product of Flex Rigid PCB board,the Flex Rigid PCB board is FPC and the Rigid circuit board,after pressing and pressing process, it is combined together according to the relevant process requirements to form the circuit board with the supporting characteristics of flexible board and rigid board.
2. Classification of Rigid Flex PCB Boards:
If in accordance with the classification process, the method of bonding the flexible board to the rigid board can be divided into two categories: the flex rigid composite board and the flex rigid bonded board,the difference between rigid flex composite board technology, can be in the process,the combination, which have a common blind and buried hole design, and can therefore have a higher density of circuit design,for flex rigid combined board,separate flexible board and rigid board again after making pressure synthesis of single circuit boards, have signal connection but without a hole design.But at present,the “Flex-Rigid PCB Board” is generally referred to as all the flexible and rigid binding board products, without dividing the two.
3. The physical characteristics of Rigid Flex PCB Boards:
Rigid Flex PCB Boards is different from the original FPC and PCB in the material, equipment and process.In the material aspect, the material of rigid board is the material of the FR4 of PCB, the material of the flexible board is the material of PI or PET, the two materials have the joint, the heat pressure shrinkage rate is different and so on.
4. Advantages of Rigid Flex PCB Boards:
1. Light weight
2. Interface layer thin
3. Short transmission path.
4. Small opening aperture.
5. Low noise and high reliability.
Because of flex rigid pcb is the combination of FPC and PCB,its production is different from the ordinary PCB and FPC, special process to specialist follow up control,firstly,KingSong CAM engineer will according to the factory production capacity to give customers a reasonable optimization, make the customer’s design can meet the PCB factory production capacity.After the flexible board is transferred through the inner layer, the surface should be browsed to enhance the binding force, and the yellow protective coat of polyimide is protected by the pressure, so the FPC is made..The next step is to combine the PP with the hardboard PCB to form a flex rigid board.It is important to note that the flexible board area cannot be polluted to prevent the appearance of the finished product.After passing through a series of drilling holes, orifices, graphic transfer,solder mask,surface treatment to get the final product.Due to the high value of Rigid Flex PCB Board products, careful inspection should be done before shipment to ensure that all the products delivered to customers are excellent products.
KingSong has rich experience in producing Rigid Flex PCB Boards,we provide the printed circuit boards in quality and durable performance while being cost-effective in terms of manufacturing.and PCBs are also tested using Automated Optical Inspection (AOI) and Automated X-ray Inspection (AXI) equipment to ensure that provide the essential speed and efficiency in an application.
