"The fourth is to focus on industrial development ecology, give full play to industrial technological advantages, create an intelligent visual feast for rigid-flex board industry, and lead the technological revolution of major industries," said the general manager of Chongqing Chiteng.
The entire flexible PCB industry is at the forefront of the industry, and we do not have any technical barriers.
The advantage of flexible PCB board compared to traditional flexible PCB board lies in its application program. These soft boards have advantages over hard boards in terms of substrate softness, flatness, and bending strength, as well as in terms of impact toughness.
In the development stage of electronic products, flexible circuit boards have become more mature. For PCBs, the most important core material is rigid boards.
So, if there are problems during the product development stage, a large number of flexible boards may need to be made due to cost considerations. At this point, using flexible circuit boards instead of PCBs has great value.

According to the anti-interference design method, electromagnetic interference below 10GHz can be effectively suppressed under EMC electromagnetic fields, while eliminating noise and interference.
A high-frequency circuit composed of two (shielded wire) wires in parallel. It includes a bidirectional symmetrical electrical main line. The left line is the source area of the cable, connected to the cable or equipment, and their adjacent cable forms a shielding layer. The right line is the connection between the cable and the transformer, and the electrical connection to the switching power supply. As a shielding layer, the cables between the transformer and the switching power supply should each pass through a shielded wire with the same model.
Offline refers to the connection between cables and transformers, cables or equipment, and the electrical connection between their adjacent two cables and cables. When the relative distance between the busbar of the transformer and the low-voltage switch transformer is relatively far, the length of the cable cross-section is reduced, that is, the cross-sectional area of the cable is reduced to ensure the overall insulation of the cable.
The cable connection line adopts copper foil single stranded wire, and the twisted pair used for signal and equipment connection of the cable is used as the equipment connection.
The current carrying capacity of the cable connection cable is used for conductors with a cross-sectional area of ≤ 05~8 km.


The inner and outer layers of the cable are made of oxygen free copper wire, with an aluminum foil thickness of μ ~ μ (50%~90%) of high-quality materials. This wire has strong insulation performance and strong corrosion resistance. Under normal conditions, its service life can reach 1000 hours.
This product has leakage current characteristics, and under specified working conditions, the leakage current changes significantly over time.
● Leakage current under normal working conditions, when the leakage current is greater than the rated value, the breakdown voltage is 267 V, and the leakage current is greater than: Ф 01~ Ф 321. Factory data.
