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

皆さん、何年か前に以下のような依頼を受けました：私は貴金属のリサイクル業者ですが、カラットを近似する方程式の妥当性を検証していただけるとありがたいです。

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,

皆さん、これから数週間、パティと教授の最初のエピソードを再掲載する予定です。いくつかの施設（中には異業種の施設もあった）を訪問して感じたのは、アップタイムというのは、その施設にとって極めて重要な要素であるということだ。

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

インジウム・コーポレーションは、はんだサプライヤーとしてよく知られているが、はんだのリサイクル能力についてはあまり知られていない。

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アセンブリマテリアルのテクニカルサポートエンジニア、ブルック・サンディ＝スミスとフィル・ザローが、真空リフローはんだ付けによるボイド低減について語ります。フィル・ザローブルック

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:

前回の投稿「リフロー・プロファイルの段階：パート1）では、リフロープロファイルの初期段階で、はんだボールの飛散やはんだペーストのスランプがどのように発生するかを説明しました。今回の投稿では

Often times solder defects such as spattering, voiding, slumping/bridging, and tombstoning can be remedied just by adjusting the reflow profile. For this reason it is important to understand the

Your first consideration when determining how much flux to use in your solder wire is whether you are doing hand soldering or robotic soldering. Robotic soldering requires a greater flux percent than

Folks, Soldering copper to copper with a tin-based solder, such as tin-lead eutectic solder or a common lead-free solder like SAC305, requires only the liquid solder and copper to form the tin-copper

皆さん、紀元前3500年頃の氷人エッツィに同情してください。銅の粒子と、銅鉱石に含まれる微量元素であるヒ素の両方が発見されたことから、彼は銅の製錬に携わっていたと考えられている。

In a previous post I mentioned some non-solder uses for low melting point alloys – meaning that they are used for purposes other than simply “joining two surfaces with a filler
