I may have made an editorial error when posting，The probe board itself is not a decryption board. With it, there is no need to weld the USB board into SATA. Simple installation can convert the USB board into SATA interface, and the SED data output of the original board is normal

Can you post more details, like the prices?

The ownership of UTS probe board belongs to 军成成。 I will no longer participate in the sales work.

Went head despite the warning... The website does not seem to be in existence. Maybe is no longer hosted or something.

Works for me. Use "http" instead of "https".

Their PCBs are very similar to these. Not to say that they are practically the same.

You are not in China and may not know the details. Some of them have received my board. Is to create at the same time, so why are the methods of protecting the probe, including the selection of


黄框内可以生产探针的胶座，箭头指向孔是为了生产胶座固定的孔
The rubber base of the probe can be produced in the Yellow frame. The arrow points to the hole to produce the fixed hole of the rubber base

There are at least three kinds of things. Is there such a coincidence? Can you call it similar?

In China, green substrates are for proofing and testing, and later production generally sinks gold. The product has only been uploaded in the past two days and is being updated. Obviously, it is making finished products and then sending drawings. Many people understand this.

Product similarity is OK. However, the protection method of the probe, the method of raising the probe, including the selection of screws, are surprisingly similar. Can't it explain plagiarism?


I am not a professional PCB designer, so there are many mistakes in doing so. I sent several people to help me test, which is also the reason why I was copied. For example, GND should be set at the board fixing column, but it was not set at that time. I have corrected it later, which can be found by comparison.

So you are the creator of those PCBs and did they copy you?

What is the cost of your PCBs?
