Technologies to Support High Quality Notebook PCs
Importance of Quality in Designing Highly Dependable Notebook PCs
Trends in Notebook PCs for Business
Recent years have seen notebook PCs growing almost daily in basic
capabilities, including processor performance, amount of memory
and HDD capacity. Their use continues to expand into a variety of
new fields. The role played by notebook PCs gains in importance
with every passing year. With this trend, the demands of business
customers have shifted from "higher performance and larger
capacity" to more durable and more stable running" machines.
To meet these demands, Toshiba emphasizes measures to improve productivity
and to reduce TCO (Total Cost of Ownership). The result is high-quality,
high-reliability PCs that incorporate Toshiba's leak-proof technology,
plus toughness that is designed into the system.
"Design to Quality" and "Design for Manufacturing" for Toshiba Notebook PC
YAMAKI Kazunori / ANDO Motoaki / IWAKI Tsutomu
With our prime consideration the customer's time, convenience, peace of mind and safety, Toshiba is constantly improving the quality of our PCs
on the basis of our policy of "Design to Quality". Furthermore, we maximize the benefits of carrying out both our design and our manufacturing work
on our own premises by applying the advantages of our "Design for Manufacturing" policy. Through close attention to detail in design, by choice of
superior manufacturing equipment, and using the ingenuity of our design staff, we are able to offer our customers PCs of high quality and reliability.
Incorporating Quality and Productivity Design Measures into Notebook PC Chassis Production
Toshiba's newly developed top-quality, highly reliable notebook PC "dynabook Satellite K series" is designed specifically for business use. From
the earliest planning and rough drawing stages, every factor was examined to reduce the in-use failure rate, including size of the base, parts
arrangement and printed circuit board (PCB) layout.
Every possible innovation was brought forward in designing the structure, parts fastening methods, hinges, chassis material, chassis wall
thickness, leak-proof parts, painting and ease of assembly. Consequently, Toshiba has reduced the number of PCBs and screws, while extending the
length of service life. The result is a more durable, yet easily assembled PC.
PCB Mounting Design Technology Supporting High Quality PCs

The printed circuit boards (PCBs) play a vital role in the quality of a notebook PC. It is essential to make improvements in the quality of PCBs
used in the manufacture of higher-quality PCs. Various electronic components, such as the CPU, a set of chips and memory modules, are mounted on
the PCBs, making them the core of a notebook PC.
In order to produce high-quality notebook PCs, Toshiba takes a proactive stance on the improvement of manufacturing quality and of mechanical
reliability, in addition to that of the electrical quality of PCBs.
Application of Highly Accelerated Life Test (HALT) to Toshiba's
Notebook PC Development
KAJI Kenji / SOMEYA Kiichiro
Toshiba has installed the HALT system in the PC development process,
expecting improvement of quality and reliability of the product,
as well as curtailment of the development period.
HALT exposes product samples to extremely harsh conditions—high/low-temperature
and rapid heating/cooling in combination with vibrations—to
disclose latent weaknesses of the product in a short time. HALT
highlights necessary corrective actions in product design, and consequently,
it helps to increase product reliability. Toshiba pursues excellent
quality in notebook PCs with the HALT system.
Leading the World in High-Quality PC Production
MURAKAMI Hiroshi / TATEYAMA Kazuki
With the wide dissemination of notebook PCs both in homes and in
business and government establishments, the importance of PC quality
has grown substantially. Good quality is an attribute that becomes
part of a PC in the earlier stages of planning, development and
design. In the later stages—during parts procurement, assembly
and shipping—a number of activities aimed at improving quality
are performed to minimize quality deterioration due to human error
so as to ensure that poor-quality products do not find their way
onto the market.
Toshiba Information Equipments, Hangzhou Co., Ltd., in Zhejiang,
China, has been able to create remarkably high-quality notebook
PCs through the development of a large number of improvement activities.
Quality and Service Information Management System
To ensure the continued quality of our notebook PCs, we have a substantial
need to acquire and analyze information on problems in the field
and to share the recognition of the situation regarding quality
in the related sections. For quality issues related to components
that are to be integrated into the PCs, quick acquisition of identification
information on these components is required in order that the scope
and degree of the problem can be evaluated.
To meet this requirement, Toshiba has developed a management system
where manufacturing data and repair data can be retrieved in an
interrelated manner. The system is designed to perform a daily collection
of data on quality and, in the event of failure or abnormality,
to promptly distribute them to the appropriate section—quality
