Rubycon products contribute to society through electronics technologies

   Today, various devices around us are computerized, and electronic devices are indispensable to the world. Capacitors are also indispensable in the electronics field, and Rubycon contributes to society through electronics technology by proposing and supplying capacitors, which are its main products, to various electronic devices.

«Conductive Polymer Aluminum Solid Electrolytic Capacitor»

  Conductive polymer aluminum solid electrolytic capacitors have a wider temperature range, are more compact, have lower ESR, and higher resistance to ripple current than other aluminum electrolytic capacitors. These features enable high-efficiency power supply design and can contribute to the reduced number of parts. The net result of this capacitor technology is energy savings improved efficiency.

«Thin film Polymer Multi-Layer Capacitors, PMLCAP»

  PMLCAP, developed with our proprietary technology, achieves extremely ideal characteristics and contributes to the high performance of electronic devices.
  PMLCAP is a surface-mounted film capacitor that achieves a significant reduction in size compared to conventional film capacitors by adopting a revolutionary technology in which electrodes and dielectrics are formed by vacuum evaporation. Compared with high dielectric constant multilayer ceramic capacitors, which have excellent frequency characteristics and temperature characteristics, they have superior "bias characteristics", "beat sound characteristics", "harmonic distortion ratio", etc.
   Its characteristics were found among developers and adopted for Mars Exploration Rover / Seismograph, which landed in the plains near the equator of Mars in November 2018. Since then, PMLCAP has been contributing as a sensing key part of ultra-sensitive seismograph to exploring the geological activities and internal conditions of Mars.

«Aluminum Electrolytic Capacitors for Automotive Use»

  With C (Connectivity) A (Autonomous) S (Shared & Service) E (Electric), the number of electronic parts installed in vehicles is increasing year by year.
  The electronic parts cost ratio of vehicles was about 3% in the 1980s, but increased to about 40% in 2015.
  At Rubycon, in addition to conductive polymer aluminum solid electrolytic capacitors, we are promoting development of products for automotive aluminum electrolytic capacitors.

«Electric Double Layer Capacitor»

  Electric double layer capacitors use "electric double layer" produced on the boundary between the electrode and electrolyte (as dielectric) for storing electric charges. This capacitor realizes quick charge-discharge cycles as well as long life since there aren't chemical reactions to store charges. This capacitor is ideal for applications requiring momentary large current such as power assist and energy regeneration. If the capacitor is used as the main power for rechargeable equipment, maintenance is reduced.

Security of Product Safety

  We, closely check compliance and non-use of banned substances in planning phase of product development, in order to secure product safety.
  We also describe safety instructions in our catalog and delivery specifications.
  We perform reliability tests with various processes to secure safety of products to be manufactured.
  We conduct reliability tests in various phases, including process design phase to secure correct materials, specifications and production conditions. During the mass production phase we check reliability of all products through regular sampling, also during the product development and planning phases. Such tests include reliability and the general process is confirmed in addition to safety, so as to maintain the reliability of Rubycon products.
  We are striving to supply safe and reliable products now and in the future.

Security of Product Safety

Response to Product Accident and Failure

  Quality Assurance Center (QA Center) receives complaints and investigation requests for accident and failure from customers through each sales office.
  QA Center uses special equipment for the primary investigation of returns and notifies complaint information to the concerned factory on the current day. Then the center starts investigation of production record and the root cause of the failure.
  Quality Control Section in the concerned factory performs expansion estimation and prepares measures to report to QA Center. QA Center reports the measures to each customer.
  QA Center further performs validation and horizontal development of the measures through internal audit, so as to confirm the change.
  Under the motto "I guarantee the quality," all of Rubycon's members are aiming to win customer satisfaction as well as addressing quality improvements.

Response to Product Accident and Failure

C0C: Claim 0 Campaign

  We, accept every complaint from customers with sincerity in order to improve customer satisfaction and quality related with product safety.
  We have started quality improvement activities as the manufacturer responsible for our products, so as to attain our goal "Claim 0."
  We started Claim 0 Campaign (C0C) in May, 2012.
  In the result of the 8th year, approximately 70% reduction in the complaint rate (number of complaints/output) has been kept. We are addressing to C0C activities to attain "Claim 0."

Transition of Claim Rate

Factory Recognition Commendation

In 2019, we received a factory award from one major customer.

Quality Honor Award
(Honor of no complains for 5 consecutive years)

Awarded by Hirose Plant of Toyota Motor Corporation

Awarded for Manufacturing Group 2,
Rubycon Corporation Main Factory

Quality Improvement Project Award

We will continue our efforts on review of work procedures, activities to prevent recurrence (C0C), and preventive measures, with the aim of further improving the quality of Rubycon group companies and product.

Improvement of Customer Satisfaction

  We have the quality policy of "manufacture to win customer satisfaction" that provides customers with relief and trust through 5 pillars of cooperation power, promptness, analyzing ability, quality control ability, small group activities. We are addressing Customer Satisfaction through quality to contribute to the society and the future.
  We conduct customer questionnaire every year including cost, delivery and service as well as quality, so as to improve customer satisfaction.

Improvement of Customer Satisfaction

ISO/IATF audit and internal audit

  We have acquired ISO 9001, IATF16949, ISO14001 and ISO45001 are engaged in production activities based on internal regulations and standards.
  As well as receiving audits by third-party organizations in order to confirm whether the production actvities are conducted firmly in accordance with the standard requirements, we are also promoting interconnection among various sections in the company and working on improvement of mutual levels, by conducting internal audits by the auditor team whose representatives are selected from each division.
