FPC circuit board can be divided into single panel, double-sided board and multilayer board according to the number of circuit layers. The common multilayer board is generally 4-layer board or 6-layer board, and the complex multilayer board can reach dozens of layers.

At present, the dividend ceiling of smart phones is gradually emerging, especially the competition in the Chinese market is particularly fierce. In January, Huawei's sales were 4.72 million units, a slight decrease of 0.4%, and sales were 10.89 billion yuan, a decrease of 1.5%.

Designing a PCB (Printed Circuit Board) for high-frequency applications requires careful consideration of various factors to ensure signal integrity, minimize losses, and mitigate electromagnetic interference. Here are some key steps and considerations:

Germanium, silicon, selenium, gallium arsenide and many metal oxides, metal sulfides and other objects, whose conductivity is between conductor and insulator, are called semiconductors. Semiconductors have some special properties. For example, the thermistor (thermistor) for automatic control can be made by using the relationship between the resistivity and temperature of the semiconductor; Using its photosensitive characteristics, photosensitive elements for automatic control can be made, such as photocells, photocells and photoresistors

Maybe many people are unfamiliar with PCB. In fact, the so-called PCB is a nickname for the circuit board. It is almost necessary to use the circuit board in the accessible places in people's life, such as computers, elevators and even smart phones that are used every day. The smooth display of their functions is actually controlled by the circuit board. Nowadays, there are a large number of PCB proofing manufacturers. What kind of PCB proofing manufacturers are more favored by users?

Rigid-flex board is a combination of flexible board and hard board. It is a circuit board formed by combining a thin layered flexible bottom layer with a rigid bottom layer, and then laminating it into a single component.The flexible board is used to replace the cable assembly to complete the highly reliable connection and transmission of power and electrical signals.The product can work stably and reliably for a long time under harsh environments such as high and low temperature, high humidity, vibration, salt spray, and low air pressure. At present, Jonhon Optronic has provided rigid and flexible printed board solutions for aviation, aerospace, ships, weapons and other fields.
