可能很多人都想知道怎么將SATA接口焊接三星硬盤的USB電路板上。
We get?many questions from our customers about how to determine the points where to solder SATA connector on SAMSUNG Spinpoint USB drive.

下面是最簡單的方法
Here is the easiest method.

USB PCB有兩種類型：
There are two types of USB PCBs:
1.使用獨立的SATA-USB橋接芯片 ;
1. With separate SATA-USB bridge;

2.將SATA-USB橋橋接芯片集成到MCP芯片中。
2. With SATA-USB bridge integrated into the MCP.

對于第二種類型，是沒有辦法焊接SATA接口的。
For the second type it is impossible to solder SATA connector.

所以在這篇文章中，我們將只討論第一種類型的PCB。
So in this article we will speak about the first type PCBs only.

起初我們應(yīng)該了解SATA接口的引腳排列。
At first we should understand the pinout of SATA connector.

然后我們看看PCB上的MCP，并確定SATA的位置。
Then we look at the MCP on the PCB and determine where the SATA differential pairs are.
大多數(shù)情況下，很容易找到它們。他們看起來像4條平行的線路朝向USB橋接芯片。
In most cases it’s easy to find them. They look like 4 parallel lines going towards the USB bridge.

如果我們無法在MCP端找到它們，那么我們應(yīng)該嘗試從USB橋接芯片端追蹤它們。
If we can’t find them on the MCP side then we should try to trace them from the USB bridge side.

他們總是穿過電容。
They always go through capacitors.
我們需要去除（拆焊）這些電容器，以從電路中切斷與USB橋接的連接。
We need to remove (desolder) these capacitors to cut the USB bridge from the circuit.

下一步是如何確定電線的布置。
The next step is how to determine the arrangement of the wires.
確定最簡單的方法是查看兼容PCB的圖片。
The easiest way to determine that is to look at the picture of a compatible PCB.

我們理解哪一個SATA接口引腳連接哪個MCP引腳
That’s how we can understand which SATA connector pin goes to which MCP pin.

地腳(1,4,7)必須連接到PCB的地上。
The ground pins (1,4,7) must be connected to the ground of the PCB
（例如任何螺絲孔或USB接口）。
(to any screw hole or to the USB connector body?for example).

最終結(jié)果
So here is the?result.

建議使用盡可能短的電線
It is recommended to make wires as short as possible.
