HI-8596PSI Manufacturers

The continuous growth of mobile phone production is driving the demand for HDI boards. China plays an important role in the world's mobile phone manufacturing industry. Since Motorola fully adopted HDI boards to manufacture mobile phones in 2002, more than 90% of mobile phone motherboards have adopted HDI boards. A research report released by market research company In-Stat in 2006 predicted that in the next five years, global mobile phone production will continue to grow at a rate of about 15%. By 2011, global mobile phone sales will reach 2 billion units.

Many illiterates believe that quantum mechanics is just a mathematical game with no practical value. Haha, let's find a ancestor for computer chips, please take a look at the demonstration:

According to the number of layers, single-sided, double-sided and multilayer circuit boards are divided according to the circuit layer inside.

The semiconductor industry is one of the key industries supported by the state and one of the most critical "bottleneck" industries. What is semiconductor?

At present, most of the holes drilled in the double-sided flexible printed board are still drilled by the NC drilling machine. The NC drilling machine is basically the same as that used in the rigid printed board, but the drilling conditions are different. Because the flexible printed board is very thin, multiple pieces can be overlapped for drilling. If the drilling conditions are good, 10 ~ 15 pieces can be overlapped for drilling.

We usually refer to metals with good conductivity such as gold, silver, copper, iron, tin and aluminum as conductors. At the same time, materials with poor conductivity, such as coal, artificial crystals, amber, ceramics, etc., are called insulators. Then, we can simply call the material between the conductor and the insulator semiconductor.
