Greenhouse Gases (GHG) 

• GHGs defined by Kyoto Protocol: 

– CO 2 (carbon dioxide), CH 4 (methane), N 2 O (nitrous oxide), HFCs 

(hydrofluorocarbons), PFCs (perfluorocarbons), SF 6 (sulfur hexafluoride) 

• Global Warming Potential of GHG 

– Global warming potential (GWP) is a measure of how much a given 

mass of greenhouse gas is estimated to contribute to global warming. 

– It is a relative scale which compares the gas in question to that of the 

same mass of CO 2 (GWP is 1).

Product green design scope 

To save the planet, Wistron is joining the green 

revolution…we are shaping the vision not only how a 

business model is crafted, but also whether a business is 

perceived favorably. With that in mind, we are asking our 

employees to think green, act green and design green. 

In design aspect, we focus on: 

• Restricted Hazardous material 

• Design for Material Reduction 

• ECO for energy saving during product design and 

producing product 

• Design for Recycle

Wistron delivers systemic management process: 

• Comply with worldwide legislation and directives of 

banned and restricted substances 

• Meet Customers' requirements of banned and 

restricted substances 

• Strictly follow Wistron restriction on hazardous 

substances 


22

Green Products management 

Being a Tier-1 ICT ODM supplier who supports customers 

with product development and manufacturing services , 

Wistron kicked off green product requirements since 2001, 

claiming that all new products must comply with Wistron 

green product requirements in which we have established the 

engineering directive documents in design, manufacturing, 

procurement aspects, such as: 

•717-R008 

•700-R014 

•717-R033 

• 717-R025 

• 717-R031 

• 904-F215 

• 901-F252

• Design for Power efficiency 

• Enhance Power Saving Mode 

– Manufacturing 

• Testing : Six Sigma DFT Initiatives 

– Implement more efficiency testing like as 

Automatic testing to reduce the testing time to 

reduce power for product testing 

– Implement lower power consumption testing 

tools & fixture (like spindle-less device) 

• Assembly : Six Sigma DFA Initiatives 

– To reduce the manufacture cycle time to reduce 

the energy for manufacturing 


25

Design For Recycling 

• Supplier Packing Material Recycling 

– To re-use the carton & packing material

Design for material reduction 

• Design of structure and material optimization 

through CAE simulation in design stage 

– Monitor--Reduced metal frame thickness (stamping sheet metal) 

from 0.7 to 0.6 mm, and part total weight is decreased. 

– Desktop PC--Reduced metal frame thickness from 0.8 to 0.6 mm, 

and total weight is decreased in products 

– All-in-One PC-- Desktop--Reduced metal frame thickness from 0.8 

to 0.7 mm, and part total weight is decreased. 

CAE simulation purpose : maintain part strength and reduce 

its thickness for material reduction and weight saving
