Re: PCB Design Software Reflections from Change in Line Width of PCB

When performing PCB wiring, it often happens that when the alignment passes through a certain area, due to the limited wiring space in the area, finer lines have to be used. After passing through this area, the lines are restored to their original width. Changes in the width of the alignment cause i...

Drilling is very important in the production process of printed circuit board

The copper foil lines between conductive patterns in different layers of circuit boards are conducted or connected by such holes, but the copper plated holes of component lead legs or other reinforcing materials can not be inserted. Printed circuit boards (PCBs) are formed by stacking many copper fo...

Generally, in PCB design, there are several reasons for signal equal length processing

Equivalent length is generally used to satisfy the system's equivalence to the signal group, that is, to satisfy the time sequence of the signals in the group, the system's requirements must be satisfied. For example, for DDR, the data signal is processed by +/-25mil in a group of 8 bits. If the equ...

What problems should PCB copper cladding deal with?

Copper cladding refers to the use of idle space on PCB as a reference level and then filled with solid copper, which is also known as copper filling. The significance of copper cladding lies in reducing ground wire impedance and improving anti-interference ability, reducing voltage drop and improvin...
