5. PLM Introduction & Design Phase Definition - EVT
Design Phase Definition
• EVT : Engineering Verification Test
• Purpose :
• Design the engineering sample, prototype, and verify all the functions to meet
product specification.
• Generate draft product BOM – E/E & ME BOM
• Pre-Scan
• Task :
• ID : Complete exterior design, color & material plan
• ME: Design & verify housing design with PCBA in structure, thermal & manufacturing
method
• EE: Design circuit, PCB and verify hardware performance & mechanical housing design with
ME
• FW & SW:
• Complete the FW & SW to test all hardware functions without fatal errors
• Complete the requirement of first release version

8. PLM Introduction & Design Phase Definition - Project
The most important elements of project
– Resource、Cost & Schedule
• Resource
• R&D
• Support Team – NPI, Procurement, SQA……
• Schedule
• Cost
• Development Cost
• Product Cost
• BOM cost – Determined at EVT
• Manufacture Cost – Determined at NPI

What is the PLM for Startup or Maker?What’s the difference between EMS &
Startup or Maker?
Originality
EMS – From Customer (Market, ID….)
Maker / Startup – Spontaneity (自發性)

13. • Market
• What pain do you solve?
• Applicability
• Emotion
• Does the pain you think is really the pain they suffer ?
( Don’t CREATE a need just because you make a product ! )
• Who is your TA (Target Audience)
• Why they are your TA?
• What is the TAM? ( Total Available Market) and
is it a big or a niche market?
• C/P ( Cost-Performance Ratio )
• Cost is not an issue but C/P is an issue

14. EVT 階段幾個重要因素
• Layout
Layout 是EVT階段最重要的因素.
• 電源和地
• 溝渠理論: 電源就如同乾淨的水源流入系統，此水源經過系統後將一些
髒的訊號借由地來排除。
• 盡量減少接地迴路
• 各區塊地對大地的阻抗值越低, 抗雜訊力越好
• 雜訊越大的地離大地的路徑越短越好
• 地越完整越好, 不要零零散散的

15. EVT 階段幾個重要因素
• Layout
• 電源和地
• 盡量避免”地”形成迴路
• Crystal trace 越短越好
• 高速CLK以地包覆或切割
• 遵守數位高速元件的Layout Guide (DDR, USB3, HDMI…)
• Thermal
• 系統的散熱不良會影響到:
• 系統消耗功率
• 元件壽命
• 電解電容 :
• 雜訊(Thermal noise)
•雜訊增強
•S/N 比下降
• 熱傳遞的方式:
• 幅射
• 對流
• 傳導

16. EVT 階段幾個重要因素
• Thermal
• 解決散熱方式:
• 風扇:對流(空氣)
• 散熱片,石墨片:傳導
• 鰭片: 對流 + 傳導 + 幅射
• 水冷式散熱: 傳導 + 對流(水)
• Thermal simulation
• Pro-E & Solidworks
• Thermal report
