쉐도잉 연습: What is IMC (Intermetallic Compounds) part II? The different between IMC, alloy, eutectic - 영상으로 영어 말하기 배우기
레슨 만드는 중...
1
Hello everyone, today I would like to delve what is IMC again.
2
The Intermetallic Compounds Part 2 Please note that this presentation is a personal sharing,
3
and the content might not be 100% accurate.
4
For more information, you can visit website of mpe.researchmfg.com So,
5
what is IMC, alloy and eutectic?
6
What are the difference between them?
7
Alloy is a term we encounter often in PCB manufacturing.
8
For instance, SAC305 is an alloy comprising 96.5% tin,
9
3% silver, and 0.5% copper.
10
But does IMC also fall under the category of an alloy?
11
In myopian, IMC isn't truly an alloy.
12
Neither is it classified as a eutectic.
13
Furthermore, IMC isn't a pure metal element due to its distinct physical and chemical characteristics that differ from traditional alloys and eutectics.
14
Interestingly, IMC is often grouped as an alloy, sparking the question of why this classification is used.
15
To distinguish between IMC, alloys, and eutectics, let's employ an analogy.
16
Imagine boys and girls as different metal elements.
17
Alloys are like mixing boys and girls in the same classroom where they coexist evenly.
18
When the boys and girls share an affinity and form eutectic points,
19
it's referred to as eutectic.
20
On the other hand, IMC is akin to a child born from the union of these boys and girls.
21
IMC emerges from a chemical reaction.
22
Please note that while this metaphor may not be perfectly precise, it's a concept and a way to understand the subject better.
23
This comparison is purely illustrative, but it helps to highlight the distinctions between IMC, alloys, and eutectics.
24
Moving forward, we'll continue exploring this subject in more detail.
25
Thank you for joining me for this second video on IMC.
26
In our next session, I'll provide a more comprehensive introduction to alloys and eutectics.
27
Until next time, take care and goodbye.
28
Thank you.

이 영상으로 연습하는 방법
- 먼저 말하지 않고 영상을 끝까지 듣고 모르는 단어를 적어 둡니다.
- 보통 속도로 한 문장씩 섀도잉하고, 화자의 리듬과 맞을 때까지 반복합니다.
- 자신의 목소리를 녹음해 원본과 비교하고, alloy, element, refer 같은 단어에 특히 주의합니다.
쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법
쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
