1
Now, PVT, the final phase.
2
Typically, how many pieces would you make, let's say a typical IoT product about this size,
3
let's say, until you actually confirm this is correct, the right quality, the right production rate,
4
we are confident that we can really just keep ramping up on this basis.
5
If we've had a successful EVT and DVT, we would shoot for a thousand units of PVT.
6
And you will not get a 99% yield rate most likely, you might have to settle with a 90% yield rate.
7
And the parts that are failing are parts then that can be used for for internal testing, they can be used for debugging,
8
they can be used for problem solving.
9
But that's typically what we would shoot for to make sure that we're ready to qualify for mass production, which is the final phase.
10
Because there's always a timing constraint right?
11
There's a budget constraint of course the longer you spend there the more it's costing everybody including the suppliers right?
12
Everybody just wants to go into mass production.
13
Yes I mean most companies they need to be shipping products to make money to keep alive.
14
If they want to wait till they don't, if they have to have 99% off the production line before they ship then they're not getting any revenue
15
and and they're not going to be able to support their efforts until probably too late.
16
So what's the timeline?
17
Let's say PVT is confirmed that maybe you're at 90-95% first time yield rate.
18
How long does it take you if there's, let's say, continuous production typically to get to 99%?
19
It could be anything from one month to three or four months.
20
depends on the complexity of the product and how diligent the product development and NPI phase has been.

中文母語者容易讀錯的音：
- 詞尾子音 — 要讀清楚，後面不要加母音: yield /jiːld/, solve /sɒlv/, continuous /kənˈtɪn.juː.əs/, depend /dɪˈpɛnd/, constraint /kənˈstɹeɪnt/
如何用這段影片練習
- 先完整聽一遍影片，不要開口，記下不認識的單詞。
- 先用 0.75 倍速逐句跟讀，熟練之後再回到正常速度。
- 錄下自己的聲音並與原聲對比，特別注意 yield, confirm, solve 這類單詞。
什麼是跟讀法？
跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
