Special Printed Circuit Board Manufacturing Service for LED Lighting (Metal Base Board)

Ideal for LED lighting products with high temperatures. Significantly reduces lifespan deterioration due to reasons other than the LED chip.

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 manufacturing - build-up boards

This is a method of forming a build-up layer on top of a core substrate.

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.

Special Printed Circuit Board Manufacturing - Impedance Control Board

Control the pattern width and interlayer thickness to perform impedance control.

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.

Special Printed Circuit Board Manufacturing - Through Hole Resin Filled Board (PAD ON HOLE)

This is a circuit board with resin embedded in the through holes and pads placed on top.

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.

Latest comprehensive catalog of a substrate specialty manufacturer 【*Includes 3 case studies!】

What is the secret behind achieving ultra-short delivery times for special substrates? Limited free sample giveaway!

At K2, a manufacturer specializing in printed circuit boards, we have all the manufacturing equipment necessary for PCB production fully equipped in-house. By operating this equipment at 100%, we achieve shorter delivery times and lower costs for special PCBs and medium-lot products, which are difficult for prototype manufacturers to handle. We address five key issues in the PCB manufacturing industry: inability to accommodate ultra-short delivery times, excessively high initial costs for flexible PCBs, being turned down for inquiries about special PCB manufacturing, inability to meet short delivery times for medium-lot production, and concerns about PCB quality. *Exclusive to Ipros users! We are currently offering samples of rigid-flex PCBs and double-sided flexible PCBs! Please contact us during this opportunity. (Limited quantities available) [Case Studies] - Resin filling (Pad on Via holes) specification ⇒ Where outsourcing would typically require an extra 3 days, we can accommodate it in 1 day! - Double-sided flexible PCBs ⇒ Achieved shorter delivery times and reduced initial costs by using laser processing instead of molds for shape processing! - 4-layer rigid-flex PCBs (without reinforcement) ⇒ Typically 7 days, expedited response in 6 days! *For more details, please contact us or download our catalog to view.

Benefits of K2: Reducing initial costs of flexible circuit boards.

Mold cost 0 yen! Cut initial costs to manufacture flexible substrates cheaply and quickly!

At K2, we do not create molds or Thomson molds (Victoria molds) for small lot production of flexible printed circuits, which generally allows us to respond to the time-consuming flexible circuit manufacturing with short lead times. Since there are no costs for creating molds, we can significantly reduce the initial costs, making our prices attractive. Furthermore, this method allows for individual correction of each circuit board, providing the advantage of high quality. 【Features】 ■ Flexible circuit board mold cost: 0 yen ■ Short lead times ■ High quality *For more details, please refer to the PDF document or feel free to contact us.
