I have enjoyed writing the Patty and the Professor blog for about 10 years now. I’ve written about numerous real-life electronics assembly examples that I have encountered in my career, all

"我經常被功率半導體的客戶問到一個問題：「如何減少晶片接合焊接的空隙？

Within the cored solder wire industry, an increasing amount of attention is being given to the amount of spatter created during robotic and hand soldering applications. New products are being

各位，好久不見了，讓我們來看看 Patty 和男孩們的情況.....。早上五點半，Patty 的鬧鐘響了。她今天異常疲倦，因為上個月有個 PTA 會議。

各位，在 Indium Corporation 的圍牆之外，恐怕很少有人會經常聽到「鎵」這個詞。然而，在某個重要層面上，鎵對現代生活至關重要：

作為一名技術支援工程師，我經常會遇到這樣的問題。焊料預型件是一種固體、扁平、製成形狀的焊料，可用於各種組裝應用。焊料

Happy New Year everyone! Typically the new year signals a new beginning, but thispost will be concluding our series on reflow profilingby discussing the fourth stage of a reflow profile: the

各位，幾年前我收到以下的請求：您好，Lasky 博士，我是一位貴金屬回收商，非常感謝您驗證一個近似克拉數的方程式的有效性。

Folks, the adventures of The Professor continue……… So far the meeting with The Professor had proven very valuable John thought.He was anxious to hear the other suggestions that The

"Well what should we do Professor?" John said weakly. "Clearly, not shut the line down over the lunch break," The Professor responded quickly. "We can't!"said John,

各位，在接下來的幾個星期裡，我打算重貼一些第一集 Patty and the Professor 的內容。我參觀了幾個設施，其中有些是其他行業的，我發現正常運行時間是一個非常重要的因素。

Folks, I teach a course at Dartmouth on manufacturing processes: ENGM 185. In this course, I use many of the chapters from “The Adventures of Patty and the Professor.” This book started as a

儘管 Indium Corporation 是知名的焊料供應商，但其回收焊料的能力卻鮮有人知。

Folks, It is accepted as fact by everyone that I know that 2/3rd of all SMT defects can be traced back to the stencil printing process. A number of us have tried to find a reference for this posit,

In my previous post on this topic, Stages of a Reflow Profile: Part II, I mentioned a few profile-induced soldering defects, including graping, tombstoning, and voiding. In this post,we will talk

This week we learned about an exciting new liquid metal-infused polymer, made with a gallium-indium alloy, which can be used to form circuits that heal themselves after being damaged. Today, Eric

Over the last few days we have learned about how to create stretchable electronics from gallium and indium embedded into an elastomer. Today we continue the conversation with Eric Markvicka and look

We are back again with Eric Markvicka to talk about how easy it is to form a stretchable electrical circuit with liquid metal-embedded material and some simple tools. Jim: Eric, at first blush your

Yesterday Eric Markvicka demonstrated self-healing electronics for us with his video of a liquid metal embedded elastomer. Today, we discuss a composite material that is electrically insulating until

PCB 組裝材料技術支援工程師 Brook Sandy-Smith 和 Phil Zarrow 討論如何利用真空回流焊來減少空洞。Phil Zarrow：Brook, 有一個

This week we will be discussing the future of self-healing electronics with Eric Markvicka of Carnegie Mellon University. At the time of writing this, Eric is a PhD Student working on his thesis:
