We get many questions from our customers about how to determine the points where to solder SATA connector on SAMSUNG Spinpoint USB drive.
Here is the easiest method.
There are two types of USB PCBs:
1. With separate SATA-USB bridge;
For the second type it is impossible to solder SATA connector.
So in this article we will speak about the first type PCBs only.
At first we should understand the pinout of SATA connector.
Then we look at the MCP on the PCB and determine where the SATA differential pairs are.
In most cases it’s easy to find them. They look like 4 parallel lines going towards the USB bridge.
If we can’t find them on the MCP side then we should try to trace them from the USB bridge side.
They always go through capacitors.
We need to remove (desolder) these capacitors to cut the USB bridge from the circuit.
The next step is how to determine the arrangement of the wires.
The easiest way to determine that is to look at the picture of a compatible PCB.
So here is the result.
It is recommended to make wires as short as possible.
If you have difficulties with the pinouts of the new PCB please feel free to contact our technical support team.
