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.
With the rapid development of electronic design and communication fields and the application of cloud computing, products have higher and higher requirements for data volume, and data transmission rates are getting faster and faster. At the same time, the performance of high-speed plates that carry data transmission is also required to be higher and higher.So what should be paid attention to when using high-speed plates?
Double-sided PCB is a very important PCB board in the circuit board, usually made of epoxy glass cloth copper clad board.
Photoelectric boards refer to PCBs used for LCD and other purposes, and have very strict requirements on size.
Now Si8000m and Si9000e also have the new option of XFE cross modeling function, Polar Instruments can provide. More than 98% of PCB manufacturers including Hongtai use Polar.
The successful first flight of the C919 large passenger plane made many people excited. However, some different voices also appeared on the Internet: saying that many parts of this aircraft are imported goods, and some even said that the Chinese C919 just made a shell.
