Our Driving Circuit Boards Capabilities 2021

Blind via PCB

 

 

Blind via, the outermost circuit layer is connected with the adjacent inner layer with an electroplated hole, which is called "blind via" because the opposite side cannot be seen.

 

Features

a) All blind via holes will be filled with epoxy resin from the prepreg sheets. Usually we cannot see it just by eyes. It's closed with a virtually flat surface of the copper lid. The via hole should be 100% filled with resin, and the thickness of the copper wall should not be less than 13μm (0.5 mil).

b) Blind via holes are often specified with a finished diameter of 0.20 or 0.25 mm (8 or 10 mils), which means that the holes can be drilled by means of 0.3 mm (12 mils) drill bits.

Amino Acid Supplements

Amino acids are the building blocks of proteins. The human body is made up of protein and amino acids are the building blocks of protein. There are 20 amino acids that our bodies require in order to survive and thrive. However, there are 8 essential amino acids that our bodies cannot make and that we must get from our diet.

Amino Acid

Amino acids are found in many foods, including protein foods such as fish, meat, eggs, nuts, beans, and soy. However, these foods are not the only source of amino acids. Amino acids are also available as supplements. In fact, amino acids are the most popular supplements, with over 1 million Americans taking them every day.

Benefits of Amino Acid Supplements

They are what make up the structure of our muscles. When we exercise, we break down our muscles and then they need to be rebuilt. If we do not get enough amino acids in our diet, our muscles cannot rebuild themselves as fast as we need them to. This can lead to injuries and muscle loss. Sports Supplement has developed an amino acid supplement that is designed to help the body rebuild its muscles faster and more efficiently.
