The following five aspects are introduced to you: 1. Brief introduction of circuit board 2. Introduction of circuit board base materil 3. Basic stack structure of circuit board 4. Circuit board production process

PCB (printed circuit board) is a printed circuit board, which is one of the important components of the electronics industry.

The advantages of heavy copper PCB make it the top priority for the development of high-power circuits. The heavy copper concentration can handle high power and high heat, which is why high-power circuits have been developed using this technology. Such circuits cannot be developed with low-copper concentration PCBs because they cannot withstand the huge thermal stresses caused by high currents and flowing currents.

A chip refers to a silicon chip containing integrated circuits, which is small in size and is a part of a mobile phone, computer, or other electronic device. If the most important organ of the human body is the brain, then chips are the "brain" of electronic devices.

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.
