山下マテリアル List of Products and Services

At Yamashita Material Co., Ltd., we offer a short delivery manufacturing service for flexible printed circuit boards (FPC). We handle not only FPC production but also pattern design, component assembly, and component procurement. We cater to a wide range of needs, from prototype production for research and development purposes to small-lot mass production. 【Features】 We provide short delivery times for small-scale production of single-sided FPC, double-sided FPC, pattern design, and component assembly. 【Delivery Time Estimates】 Single-sided FPC: Shortest delivery time of 1 working day to standard delivery time of 15 working days Double-sided FPC: Shortest delivery time of 2 working days to standard delivery time of 20 working days FPC assembly: Additional 1 working day to the above delivery times. *Weekends, holidays, and designated company holidays are not counted in the delivery time. *Delivery times may vary depending on product specifications and quantities. *There are restrictions on the number of components for assembly. The standard specification is for 30 or fewer components for single-sided assembly and 30 or fewer boards.

The "LDVS Type Microstrip Line (RFM)" is a high-performance version of the popular YFC series. It uses liquid crystal polymer (LCP), a low dielectric constant material, as the base film to reduce transmission loss. There are types ranging from RFM1 to RFM4, so please check the catalog for details. We offer two types for insulation: one using liquid crystal polymer film and the other using polyimide film. The type using liquid crystal polymer film for insulation aims for further reduction in transmission loss. Please choose according to the scene in which you will be using it. 【Features】 ■ Reduces transmission loss by using liquid crystal polymer as the base ■ The type using polyimide for the coverlay can accommodate hand soldering ■ Improved bending performance due to the adoption of mesh GND *For more details, please refer to the PDF materials or feel free to contact us.

The "LVDS Type Strip Line (RFS)" uses liquid crystal polymer, a low dielectric material, as the base film, aiming to reduce transmission loss. Additionally, it is suitable for EMC measures due to the use of a shielding film. The adoption of a mesh ground improves flexibility. 【Features】 ■ Reduces transmission loss by using liquid crystal polymer as the base ■ Implements EMC measures with a shielding film ■ Improves bending performance through the adoption of a mesh ground *For more details, please refer to the PDF document or feel free to contact us.

The "LVDS Type Coplanar (RFC)" is a high-performance type of the YFC series. It uses liquid crystal polymer, which is a low dielectric constant material, for the base film to reduce transmission loss. There are two types available: one that uses polyimide film for insulation (RFC1) and another that uses liquid crystal polymer film (RFC2). Additionally, due to its coplanar structure with single-sided wiring, it offers the greatest flexibility among our LVDS-compatible flat cables. 【Features】 ■ Reduces transmission loss by using liquid crystal polymer as the base ■ Offers the greatest flexibility among LVDS types due to single-sided wiring *For more details, please refer to the PDF document or feel free to contact us.

The "L Shielded Type (SFC)" is equipped with a shield film applied to our YFC. An essential item in scenes where EMC measures are required. The shield film uses a thin membrane, ensuring that flexibility is not compromised. 【Features】 ■ YFC cable using shield film ■ Utilizes thin film shielding ■ Excellent flexibility *For more details, please refer to the PDF document or feel free to contact us.

The "LDVS Type with Ear and Notch" features a locking mechanism with protrusions and recesses on the terminal part, tailored to the specifications of the connector. It is particularly suitable for environments with high vibrations, use in equipment under tension, or situations where twisting is applied to the drive part, as it helps prevent connector disconnection. The total length of the cable can be made to your specified length (up to 340mm), number of cores, and pitch. 【Features】 ■ Compatible with the protrusions and recesses of the specified connector terminal ■ Can be made to your specified length, number of cores, and pitch ■ Compliant with UL certification specifications ■ Standard products do not require initial costs *For more details, please refer to the PDF document or feel free to contact us.

The "Normal Type" is a flexible flat cable that replaces FFC with excellent bending and bending resistance. It can be made to your specified length, number of cores, and pitch. It complies with UL certification specifications, and standard products do not require initial costs. 【Features】 ■ Can be made to your specified length, number of cores, and pitch ■ Can comply with UL certification specifications ■ Standard products do not require initial costs *For more details, please refer to the PDF document or feel free to contact us.
