セミアディティブ法は、アディティブプロセスのもう一つの形態である。これは プリント基板製造工程 は、紫外線を照射してフィルムを硬化させ、電気めっき技術により、ラインの銅厚をお客様の要求する厚さにまで厚くします。最後に、フォトレジストの下にある余分な銅層をフラッシュエッチングで除去し、目的の回路パターンを得ます。電子デバイスの進化に対応した新しい方法だ。この方法を用いると、銅厚は線幅に影響されず、最小線幅/線間14μm/14μm、最小開口部55μmのフレキシブル基板を製造することができる。
The manufacturing of the FPC is only the first step in a turnkey service. Surface preparation is usually required for fragile circuit boards to ensure that the circuit boards are in an acceptable assembly condition. Immersion gold, immersion tin and immersion silver are not the only options in surface treatment services as we offer a much greater range of other surface treatment services (HASL, lead-free HASL, plated gold, etc). In addition to technical advantages, the provision of free conformal paint service in small-batch prototype manufacturing orders is one of the primary factors that FS Technology has received well.
The combination of electronic components and assembly techniques enables endless possibilities for your flexible projects and FS Technology has the capabilities to support your project needs. FS Technology not only provides traditional SMT assembly and through-hole assembly but also flip-chip technology that inverts the chip and connects directly to the substrate.
Additionally, FS Technology has a complete quality management system and involving PCBAテスト in the assembly process is a critical part of the overall factory process, which includes free manual visual inspections and AOI testing. Accompanying these basic tests on flexible PCBA boards, ICT, flying probe testing and X-ray testing are additional compulsory tests that are required and performed during the manufacturing process of your electronic projects.
The technology used for flexible boards, also known as FPC or flexible printed circuit boards, are widely utilized in various fields and industries, which include consumer electronics, wearables, telecommunications, aviation, etc. Normally, flexible PCBAs exist in the form of single-layer boards and higher-density boards such as 8-layer, 10-layer or even 16-layer flexible boards, which are typically produced according to the needs of a project. If you choose FS Technology as your turnkey FPC supplier, we are capable of supplying all types of flexible PCBs that follow these characteristics:
- Smaller and lighter substrates are used for flexible circuit board creation, measuring approximately 0.004 inches. Considering a minimalistic space and area, it is more suitable for complex circuits in a smaller footprint compared to other ordinary boards.
- If flexible boards are combined with rigid boards, the resulting boards, called rigid-flex boards, offer a combination of the features from both board types. That is to say, rigid-flex boards not only make up for the lower tensile strength (weakness) of flexible boards but also make up for the inflexibility of rigid boards.
- Compared to other boards, High-end flexible PCB boards can reduce the risk of construction errors and repairs as well as provide protection for the advancement of the project.
- Our flexible PCB come with the feature of easy airflow that cools the circuitry of the board.
- The modifications in the structure of flexible 多層PCB ensure that the construction of complicated structures and designs has adaptable features to make strong connections at the board corners.
Price of flexible PCB
The price drivers of PCBA include material, size, structure, purchase volume, etc. Regarding retail, this may mean that the finished product seller may increase the profit of the project through these aspects. Under the same conditions, the price of circuit board types are in the order of rigid < flexible < rigid-flex, but from the perspective of the use of PCB materials, FPC boards use fewer materials and components. In terms of manufacturing materials, more manufacturers choose to use polyimide materials that are less expensive and are key materials in flexible PCB production. In terms of PCBA components, due to the recent global pandemic, the major downturn and shortage of component supply have skyrocketed the price of chip components so by using flexible PCBs, you may be able to save more on this aspect. On top of that, in regard to the personnel needed for production, flexible circuit boards can be built with the fewest number of technicians.
Applications of flexible circuits
Facing the environment of high-voltage and high-temperature circuits, customers often will choose IMS PCB due to its high thermal management performance, but circuit boards with metal layers as inner layers obviously cannot meet many customers’ needs for complex circuits. As a result, flexible circuits are mainly brought up as their first choice. In some severe cases, circuit boards with poor heat dissipation may release harmful chemicals when misused but premium flexible PCB boards offer that needed resistance. Flexible PCBs are made of polyamide or polyester film as the base material, which greatly increases their thermal stability and performance. Be sure to keep in mind that when electronic products face the threat of high temperatures, although rare, the physical phenomenon of thermal expansion and contraction may occur, causing a drop in overall performance. Subsequently, these flexible boards have features to operate on any type of connector used in electronics, especially compatibility with ZIP connectors.
Size of flexible PCB
As foldable circuit boards, flexible PCBs can not only provide three-dimensional space design freedom for projects but also improve space utilisation and weight efficiency in equipment. These boards require less area and lighter weight, and the use of a smaller footprint allows them to provide better functionality in full-featured large-scale projects. In small, reliable and consistent circuits or projects, flexible boards can also be installed in places where rigid circuit boards cannot because flexible PCBs utilize much fewer connectors and interconnects.
Flexible printed circuit boards (FPC) are considered to be an integral part of any electronic device as they can be applied to a vast variety of electronic products, such as computers, keyboards, cameras, mobile phone circuitry, etc. FS Technology has been active in the FPC manufacturing and assembly industry for ten years and within this timeframe, we have worked with many customers from a massive range of industries who use our flex PCB services for the computer and medical industries. The use of flexible PCBA is not limited to this though as the possible applications are very extensive, some of which we will introduce to you now.
Flexible PCBs are created for a diverse scope of manufacturing projects in several industries, including robotics, which commonly uses this type of PCB. HMI machine layout is also configured over these boards and machines that are commonly found in shopping malls (e.g. bar code readers) contain these boards with processing devices integrated with flexible PCBs.
Plus, these flexible printed circuit boards are commonly used in GPS systems within vehicles as the control systems that have been engineered in automobiles are usually manufactured over these boards. Currently, in new vehicles, most of the latest breaking systems that are installed (e.g. antilock brake system) make great use of these boards in manufacturing, in addition to airbag deployment systems.
Over in the medical industry, state-of-the-art hearing instruments and heartbeat sensors are created around flex medical PCBs.
Moreover, different types of electric components, such as active and passive devices, are designed through the use of flexible boards, like high towers, light circuits, etc. Other applications of these boards include the likes of satellite stations & communication grid circuitry, where application-specific resistors and capacitors are created to use these boards for different circuit types, including ripple and filter circuits.
