Single-sided flexible printed circuit boards are available in various material thicknesses. By using thin materials, we can achieve flexible printed circuit boards with a total thickness of just 50μ. We can also provide fine pattern substrates using thin copper foil materials, and we can accommodate halogen-free options as well. For more details, please contact us or refer to our catalog.

• Printed Circuit Board

Like one-sided flex, we have a variety of materials in stock. The thinnest option allows for a total thickness of 100μ for flex PCBs, and of course, we can also accommodate halogen-free requirements. For more details, please contact us or refer to our catalog.

• Printed Circuit Board

We can manufacture from 3 layers to 8 layers. Typically, with multilayer flexible circuits, the more layers there are, the thicker the board becomes, which compromises the bendability that is a characteristic of flexible substrates. However, by using thin materials and thin copper foil, we ensure bendability. For more details, please contact us or refer to our catalog.

• Printed Circuit Board

We can produce from 2 to 8 layers. When it comes to rigid-flex PCBs, it often requires creating molds, which can be very expensive even for prototypes, and the production time can be significantly long. At K2 Corporation, we combine our experience as a rigid PCB manufacturer with our experience as a flexible PCB manufacturer to offer quick turnaround and low-cost prototypes of rigid-flex PCBs. We can flexibly accommodate complex shapes and special layer configurations, so please feel free to consult with us. For more details, please contact us or refer to our catalog.

We offer a variety of materials, including aluminum and copper, in different thicknesses, allowing for the production of metal base substrates with various specifications. LEDs are characterized by their energy efficiency, brightness, and long lifespan; however, one drawback is that their lifespan can decrease due to factors other than the heat generated by the LED chip, which can be problematic. Metal base substrates are designed to dissipate the heat generated by the LED during operation. By using materials such as aluminum or copper, which have good thermal conductivity, we can effectively dissipate the heat generated by the LED. For more details, please contact us or download the catalog.

• Printed Circuit Board

We use FR-4 (glass epoxy substrate), FR-1 (paper phenolic), and CEM-3 (composite) as standard materials. We offer a wide range of thicknesses from 0.5mm to 2.0mm to meet our customers' needs. *Other thicknesses can also be accommodated by using double-sided materials. We can ship within the shortest possible working days of 1 day. For more details, please contact us or refer to our catalog.

• Printed Circuit Board

For more details, please contact us or refer to our catalog.

• Printed Circuit Board

The precision of printed circuit boards has advanced, leading to an increased demand for printed wiring boards using the build-up method. The build-up method is a construction technique that forms build-up layers on top of a core substrate. The connection between the core substrate and the build-up layers is made using laser vias. By using this method, it becomes possible to achieve higher density wiring. Currently, we can accommodate up to two-layer builds (two layers of build-up layers above and below). Additionally, we can also handle stack vias and filled vias. We have a track record of manufacturing rigid-flex boards and multilayer flex boards using the build-up method. For more details, please contact us or refer to our catalog.

• Printed Circuit Board

This is a substrate that connects only the necessary layers without penetrating the holes in a multilayer board. As the number of layers in printed circuit boards has increased, the demand for this has also grown. It can be manufactured using either blind via holes that connect the outer layers to the inner layers or inner vias that embed through holes in the inner layers. Additionally, it is compatible not only with standard multilayer boards but also with multilayer flexible boards and rigid-flex boards. For more details, please contact us or refer to the catalog.

• Printed Circuit Board

Based on our extensive past experience, we control the pattern width and layer thickness to perform impedance control. By using the Polar company's impedance simulation software 'Si8000', we can pre-calculate the impedance values of the completed circuit boards, enabling accurate impedance control. Additionally, we can simulate the layer configuration, line width, and spacing during the pattern design phase, allowing us to propose specifications that facilitate easier impedance control. For measuring the impedance of the completed circuit boards, we use the 'MZPC50' measuring instrument from Microcraft Co., Ltd., and we can provide measurement results (using the TDR method). For more details, please contact us or refer to our catalog.

• Printed Circuit Board

This is a circuit board designed to secure the mounting space for components by embedding resin in through-holes and providing pads on top. With the trend towards narrower pitches for components such as BGA and CSP, the demand has increased. Resin and metal paste are embedded using vacuum printing. For more details, please contact us or refer to the catalog.

• Printed Circuit Board

When a standard thickness of 18μ copper foil carries a large current, it can generate high heat and, in some cases, may even break, which is very dangerous. Such substrates can be addressed by increasing the thickness of the copper foil, and K2 Corporation can manufacture substrates with thicknesses ranging from 35μ to 105μ using standard substrate manufacturing methods. Furthermore, by employing special manufacturing techniques, it is possible to produce substrates with a maximum copper foil thickness of 400μ. For more details, please contact us or refer to our catalog.

K2 Corporation is equipped with large-capacity facilities as a prototype manufacturer, allowing us to produce not only small lots but also medium lots and even small-scale production with short lead times. Thanks to the 100% operational rate of our large-capacity equipment, we can respond without any issues to sudden requests, even if the quantities are large. Additionally, since our manufacturing methods are the same as those for prototype boards, the initial costs do not become excessively high like they do with mass production factories. When there are requests for medium lot manufacturing, general prototype manufacturers may struggle to keep up with factory capacity, leading them to outsource or decline the manufacturing altogether. Even when requesting mass production manufacturers, initial costs can be high, or delivery times may be significantly delayed. Our company has a large factory capacity, allowing us to seamlessly integrate medium lots into our production line and manufacture them on the same line as prototypes, ensuring we can also accommodate short lead times.
