As everyone knows, the mythical Monkey King’s stick is called an embroidery needle, but you know, with the continuous advancement of modern technology, in reality, it is really a needle-point embroidery-sized drill. Today, circuit board manufacturers will show you the real version. "Needle-point embroidery" drill, what is the thinnest drill you have ever seen? Is it the following?

Or is it like this?

If the Honglian editor tells you

Now our country can produce

Ultra-fine micro drill with a diameter of only 0.01mm

Will you drop your chin?

This is about one-eighth the thickness of human hair~

0.01mm diameter ultra-fine micro drill

It is the thinnest drill bit that can be manufactured in the world!

What role do small drills play in the industrial system?

Circuit board manufacturers help you popularize science. As a key component of the electronic information industry chain, printed circuit boards (PCBs for short) are widely used in communication electronics, computers, automotive electronics, medical equipment, national defense, aerospace and other fields. Micro-holes are the key structure of printed circuit boards, mechanical drilling is the mainstream processing method for printed circuit boards, and precision micro-drills are key tools for processing printed circuit board micro-holes.

Today, with the rapid iteration of electronic information technology, circuit boards as base products are also required to be more and more sophisticated. Various new types of PCBs are constantly being developed. Development in the direction of higher and higher performance.

Where is the manufacturing technology of ultra-fine micro-drills?

This ultra-micro drill can also engrave spiral angles that cannot be observed with the naked eye. The difficulty has long surpassed that of “needle-point embroidery”. Now the ultra-micro drill has been widely used on printed circuit boards closely related to integrated circuits. This 0.01mm drill bit also broke the situation that China is subject to others in the field of ultra-fine and micro drill bits.

Ten years ago

my country can only produce micro drills with a diameter of 0.1mm

"Ten years to sharpen a sword"

Finally practiced

The "unique skill" of the 0.01mm ultra-fine micro drill

Then some friends are going to raise their hands and ask questions.

Where is the 0.01mm diameter micro drill used?

Although there is no market application demand for this diameter product, the editor of Honglian believes that Chinese companies have mastered this key core technology, which will prevent the future development of the national electronics industry from facing the "stuck neck" problem, and will be useful for enhancing domestic electronics, communications, The autonomy and controllability of the supply chain of automobile and other industrial chains and ensuring the safety and stability of the industrial chain supply chain are of extremely important significance.

As a PCB circuit manufacturer, although we are not professional scientific researchers, we cannot make the application of this technology worse and benefit everyone, but as a circuit board manufacturer, we can also use our expertise and hands to work silently and create countless sets. There are countless high-tech PCBs using this technology.
