Regulations

We have established Green Procurement Guidelines and are working to reduce lead, comply with the RoHS directives on restricted substances and halogen compounds contained in our products, and comply with the REACH regulations.

Concept behind Green Procurement Guidelines

Management of chemical substances contained in products is important to comprehensively guarantee the selection of raw materials and components -- from product planning to delivery of products to customers.

  • We give preference in selecting and procuring materials and components that have reduced environmental impact.
  • We regularly evaluate the status of our business partners' efforts to manage chemical substances contained in products, and we procure from those who are capable of management on a continuous basis.
  • Our advance approval must be obtained for any changes in the processes, raw materials, etc. of our business partners.

All products conform to the lead-free and RoHS directives

We are promoting 100% lead-free Sn plating for semiconductor products. This also complies with RoHS directives (2011/65/EU, 2015/863/EU).

Maximum concentration (threshold) allowed in specified chemical substances and homogeneous materials

Cadmium (Cd) 100ppm
Lead (Pb) 1000ppm
Mercury (Hg) 1000ppm
Hexavalent chromium (Cr 6+ ) 1000ppm
Polybrominated biphenyl (PBB) 1000ppm
Polybrominated diphenyl ether (PBDE) 1000ppm
Bis(2-ethylhexyl) phthalate (DEHP) 1000ppm
Dibutyl phthalate (DBP) 1000ppm
Butyl benzyl phthalate (BBP) 1000ppm
Di-isobutyl phthalate (DIBP) 1000ppm

This does not include (below the maximum permissible concentrations) substances restricted by China RoHS (II).

For halogen free

We are promoting halogen-free semiconductor products.

Chlorine (Cl) Less than 900ppm
Bromine (Br) Less than 900ppm
Total content (Cl + Br) Less than 1500ppm

Response to REACH regulations

As of April 2022, we have confirmed that the content of 218 Substances of Very High Concern (SVHC) in semiconductor products is below the threshold.
In response to customer requests for chemical substance information, we can provide information via the following information transmission methods.

Please contact our Sales Division for our response to the REACH regulations.

In order to achieve quality that satisfies our customers, we show the process from planning, development, production to shipping and collaboration with each other.

Quality assurance

We evaluate the suitability of quality and reliability designs by reliability testing based on accumulated reliability data.

Reliability test

Semiconductor products are easily affected by the surrounding environment, so please handle and store them with sufficient care.

Instructions

Introduces the in-house analysis system and analysis examples for identifying the location of failures and cause of defects.

Failure analysis

Process information from production, processing, inspection, and shipping of products is recorded by lot number, which makes searching and tracking possible.
