Achieve faster and sustained recovery growth. The industrial added value has achieved rapid growth. Can the rigid-flex board industry achieve sustainable growth in the past 20 years?
In 2018, the global PCB industry market size was 18.9 billion US dollars. Due to the constantly changing global economic water level, the global PCB industry has experienced a year-on-year growth rate of 361% from January to April.
The PCB industry has maintained a growth trend for six consecutive months, especially with the continuous expansion of developed countries such as Japan, South Korea, and Taiwan in the future, which will also make the output value of the Japanese PCB industry expected to increase from $8 trillion to $21 trillion. The massive global Internet of Things and high-speed data transmission equipment have driven the growth of the PCB industry, and the growth potential of the global PCB industry will also be significantly improved.
In the face of double-sided boards and soft hard combination boards, the industry must also consider different PCBs as the pillars of the industry.

The function of a printed circuit board is to connect the input voltage of electronic devices to the input current region of the circuit system. When connecting wires, copper wire and gold wire or wire harness are twisted together to form the interconnection of the various functions.
The main body of inductance between the wire bundle and the cable. If two insulated conductors are placed in the same place, the circuit will have low impedance and this impedance can be controlled.
Insulate the cables with insulating materials to ensure the accuracy of specified and measured data.
Evenly transmitting voltage and current to the instrument results in a clear trend in the standardization of current and voltage.
When actually measuring, set the voltage of a differential cable first. For the protection of signal lines, as well as various accident signals and lightning protection measures used for protection, it is required to ensure that the insulation does not pose a danger to the human body due to electric shock and counterattack,
The data flow for data transmission needs to be transmitted to the input and output cables on the instrument. What are the characteristics, versatility, transmission methods, and high-density parameter requirements of data cables.
A type of impedance between cables: The impedance of a cable refers to the impedance between cables with components at both ends when the impedance of the signal cable is zero.
The resistance of a copper strip conductor is that of a copper strip conductor, which refers to a length of 20-30 μ Between m, at the end is the core wire of the aluminum strip, which means that the two ends of the wire are connected in parallel with resistors, so that the resistance of the conductor stabilizes at zero. For aluminum strips, their shielding includes: shielding is only for electrical insulation; For copper strip, its shielding property forms a shielding device, which is usually the opposite of aluminum strip. For conductors, aluminum strips also have electrical insulation. The lifespan and thermal conductivity of aluminum strips are important factors.
In order to further improve the performance of insulation resistance, it is necessary to improve its performance. Copper tape and its thermal conductivity are much higher than the thermal conductivity, but the conductivity is much lower than heat dissipation. If copper strip is not added, it has the following characteristics.
