• Resistors

We will introduce one of our core technologies, the cutting process, with accompanying illustrations.

Small carbon, metal film, metal oxide film, and metal glaze thick film resistors are one of the main products of Rikyu Electric. We are introducing the important process of cutting with illustrations. If you are looking for alternatives due to the discontinuation of existing part numbers or if you are interested in the cutting process beyond resistors, please take a moment to read our materials. We also undertake partial processes, not just finished product sales. If you are interested, please feel free to contact us. Flow after downloading the materials: 1.

• Resistors

We will introduce one of our core technologies, the lead cap welding process, along with illustrations.

The lead cap functions as the electrode of the resistor by being pressed into the ceramic insulator. We are introducing the welding of lead caps, which is important in the manufacturing of special-sized resistors, along with illustrations. If you are having trouble with existing products due to mismatched cap sizes, or if you are interested in lead caps beyond just resistors, please take a look at our materials. We can flexibly accommodate cap sizes, lead wire diameters, and terminal shapes. If you are interested, please feel free to contact us. Flow after downloading the materials: 1.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm. Please feel free to contact us for more information!

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
