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

“How do I reduce my die-attach soldering voids?” is a question I am often asked by customers in the power semiconductor

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

朋友们，好久不见，让我们来看看帕蒂和男孩们的生活.....。早上 5:30，帕蒂的闹钟响了。她今天异常疲惫，因为上次参加了家长教师协会的会议。

各位，铟泰公司 之外，恐怕铟泰公司 经常听到镓（Ga）”这个词。然而，从一个重要方面镓（Ga） 对现代生活镓（Ga） ：

As a technical support engineer,I get this question quite often. A solder preform is a solid, flat, manufactured-shape of solder that can be used for a wide variety of assembly applications. Solder

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

朋友们，几年前我收到了以下请求：你好，拉斯基博士，我是一名贵金属回收商，非常希望您能验证一个近似克拉数的等式的有效性。

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,

朋友们，在接下来的几周里，我计划重新发布《帕蒂和教授》第一集的一些内容。我参观了几家工厂，其中一些是其他行业的工厂，我发现正常运行时间与其他行业的工厂一样重要。

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

虽然铟泰公司 焊料供应商铟泰公司 ，但其焊料回收能力却鲜为人知。铟泰公司焊料回收计划采用最先进的电解

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

Brook Sandy-Smith, Technical Support Engineer for PCB Assembly Materials, and Phil Zarrow, discuss how vacuum reflow soldering can be used to reduce voiding. Phil Zarrow: Brook, there's been a

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:
