Quality and Reliability Assurance / Handling Precautions
Quality And Reliability Assurance / Handling Precautions
In recent years, technical revolutions have become almost a daily occurrence in the
electronics industry. This is accompanied by the increasing application of semiconductors in
both the consumer and industrial sectors, and demands for higher quality and higher
reliability.
Toshiba is making every effort to improve both quality and reliability with the following
quality control system which incorporates product design, quality assurance for parts and
materials received, manufacturing process quality assurance, shipping quality and
reliability assurance, and quality after-service based on user demands and market survey
data.
1 Quality And Reliability Assurance
1.1
Quality Assurance
Trying to sense the customer’s needs, we do our best to incorporate the quality and
reliability required by the customer into the design, while considering the safety
and PL (Product Liability) of the products.
Quality and reliability evaluation are performed on the developed products
according to the Toshiba’s reliability test standard which is prepared in conformity
with JIS, EIAJ, MIL, etc., thereby certifying the design. The parts and materials
are standardized through the engineering department and the quality assurance
department. After the design is accepted, standardization is performed by the
engineering department on the parts and materials, process plan, and inspection
plan. Engineering Institution of Works (EW) is then established on the working
detail. The quality and reliability evaluation are performed on the mass-produced
products on an experimental basis.
In the mass production, the production department has control of the
manufacturing process, the environment and facility, and the quality assurance
department. Quality assurance performs incoming inspection of parts and
materials, modification control, instrument control, periodical reliability test and
line audit. The production technology divisions also participate in process
improvement, automatization, etc.
Education and training for quality and reliability, are given to new workers,
inspectors, engineers and small groups (QC/ZD movement). In shipping the
finished products, a lot quality assurance test is performed by the quality assurance
department. We then commence preparation of specifications meeting pre-arranged
quality and reliability standards and the inspection and reports on discrepant
products “quick action” as the motto. Figure 1 shows the quality assurance system
of semiconductor.
