The OC48 interface card contains several typical mixed-signal PCB layout and routing problems, the layout and routing process will indicate the sequence and steps to solve the mixed-signal PCB layout solution.
With the development of the electronics industry, the demand for printed boards is getting higher and higher. Printed board design of high density, thin wire, small aperture trend faster and faster, printed board production process is becoming more and mo
In China, the demand for backplanes mainly comes from the communications industry, which is now growing in the field of communications equipment manufacturing.
In this process, all surface areas and boreholes are plated with copper, some resistance is poured on the surface of the unwanted copper, and then etching resistance metal is plated.
Soft and hard combination board is considered appropriate and the use of rigid (FR4) materials and flexible (PI or PET) materials combination, is a kind of both rigid PCB durability and flexible PCB suitable force of the new printed circuit board.
If the contact or line on the PCB circuit board needs to contact with the parts over and over again, with the passage of the product office hours, the appearance of the metal will reveal a certain wear, so the contact is not good.
Flexible circuit board has the characteristics of short, small, light and thin; It has the characteristics of high assembly density and small volume. There are high cost, long cycle, complex inspection methods, etc., which is a process that all FPC circui
