lab632: RE:陳永村: Coffin Manson

您好,
謝謝您的提問,
Coffin-Manson公式為加速因子的公式,
傳統的公式僅考量 通路斷路間溫度差/焊錫熔點溫度
而改良的公式會加入循環試驗的次數及其他參數
以更加符合待測物的壽命測試情況

若需要更多的資訊,
可以參閱這個ppt
及GOOGLE圖書的線上資源中有很多資源可以查詢
推薦給您Guangbin Yang《Life Cycle Reliability Engineering》這本

陳永村: Coffin Manson

我是敬鵬工業(生產電路板)的品保工程師,陳永村,

因為在網路上有看到一篇關於可靠度的文章『DOM 產品可靠度試驗』。

我們對於這篇文章提到的冷熱衝擊預測產品壽命非常有興趣,

但其中關於 Coffin Manson 這個公式不了解,可以跟您請教一下這個公式是什麼嗎?

或者有哪些文章或書籍是介紹這個公式的?

Zack: Re:Harry: 什麼是工業4.0

Thank you for your inquiry.Industry 4.0 is a collective term for technologies and concepts of value chain organization. Based on the technological concepts of cyber-physical systems, the Internet of Things and the Internet of Services, it facilitates the vision of the Smart Factory. Within the modular structured Smart Factories of Industry 4.0, cyber-physical systems monitor physical processes, create a virtual copy of the physical world and make decentralized decisions. Over the Internet of Things, Cyber-physical systems communicate and cooperate with each other and humans in real time. Via the Internet of Services, both internal and cross-organizational services are offered and utilized by participants of the value chain.
