In an ultra-high vacuum environment, transmission lines encompass not only cables but also Flexible Printed Circuits (FPCs). Ordinary FPCs use a polyimide substrate that absorbs moisture, resulting in longer evacuation times from normal to ultrahigh-vacuum environments. However, Junkosha employs a fluoropolymer base material with minimal moisture absorption. By integrating the cleanliness concept of super low outgassing cables (SLO) with thin-wire technology (up to AWG50), derived from medical probe cables and other products, we have developed a flat cable that matches the flexibility and space-saving attributes of FPCs. Our FPC Alternative SLO Cables offer the same flexibility and space-saving characteristics, despite being flat cables. By selecting the thinnest possible conductor based on the required current, we are also able to minimize the use of PFAS materials.

We customize cables to match the shape and number of cores required for the FPC connector pitch. Additionally, we offer shielded cables optimized for signal transmission, including twisted pair shielded cables ideal for digital transmission.
