What is Rigid-Flex PCB:
Rigid-Flex printed circuit boards are boards have both of flexible and rigid board feature. Most rigid flex boards consist of multiple layers of flexible circuit substrates attached to one or more rigid boards externally and/or internally, depending upon need of the application.
Rigid-Flex PCBs Fabrication Applications:
Rigid-flex PCB is widely used and has penetrated into all walks of life from daily consumer electronics. Due to its ability to save space and reduce weight, rigid-flexible board manufacturing is increasingly used in precision instruments such as pacemakers. The same advantages of using rigid-flex boards can also be applied to intelligent control systems. The rigid-flex combination not only maximizes space and weight (the flexible PCB part is particularly good at overcoming the space and weight issues of spatial freedom.), but also greatly improves reliability and eliminates most of the difficult-to-solve problems that arise during the production process. .
Rigid-flex board technology and production process:
The rigid-flex manufacturing stage is also more complex and time-consuming than rigid panel manufacturing. All flex components of rigid-flex components have completely different handling, etching and soldering processes than rigid FR4 boards
Whether producing rigid-flex prototypes or mass production of rigid-flex PCBs, fully proven and reliable technical requirements are required. Manufacturers should consider the feasibility of solutions from the early stages of the design phase and be involved in the entire product process from design to production to ensure that the design and manufacturing parts are coordinated and changes in the final product are taken into account.
Benefits of Rigid-Flex PCBs
• Simplifies the dependence on components between rigid components and reduces the weight of the entire circuit board.
• Reduced solder joints improve connection reliability.
• The assembly process is easier to handle than flexible circuit boards.
• Simplified PCB assembly process.
• Significantly reduced logistics and assembly costs.
With the development and improvement of printed circuit technology, the development and research of rigid-flex boards have been widely used. It has become an inevitable trend for circuit boards to develop in the direction of being light, thin, short, small, and multi-functional, especially for high-density interconnect structures. The application of (HDI) rigid-flex boards will greatly promote the rapid development of circuit technology, and it is expected that the global supply of rigid-flex boards will increase significantly in the future. At the same time, the durability and flexibility of soft-hard composite boards make them more suitable for medical and military applications, gradually eroding the market share of rigid PCBs.
Although the product is good, the manufacturing threshold is somewhat high. Among all types of PCBs, soft and hard bonding boards have the strongest resistance to harsh application environments, making them favored by medical and military equipment manufacturers. Soft and hard bonding boards combine the durability of rigid PCBs with the adaptability of flexible PCBs. Enterprises in Chinese Mainland are increasing the proportion of such PCBs in the total output to take full advantage of the great opportunity of growing demand. Reducing the assembly size and weight of electronic products, avoiding wiring errors, increasing assembly flexibility, improving reliability, and achieving three-dimensional assembly under different assembly conditions is an inevitable demand for the growing development of electronic products. Flexible circuits, as an interconnection technology with thin, light, and flexible characteristics that can meet three-dimensional assembly needs, have been increasingly widely applied and valued in the electronics and communication industry.
The following three boards are Rigid-Flex board which was made by us.
With the continuous expansion of its application fields, the technology of flexible circuit boards is also constantly developing, such as from single-sided flexible boards to double-sided, multi-layer, and even rigid flexible boards. The application of thin line width/spacing, surface installation and other technologies, such as the material characteristics of the flexible substrate itself, has put forward stricter requirements for the production of flexible boards, such as substrate treatment, interlayer alignment, control of dimensional stability, and decontamination, The reliability of small hole metallization, electroplating, and surface protective coating should be highly value.
