Very important. Once the signal gets into the ground plane from the circuit, there will be a ripple. Ripple may spread and influence the signal in other circuits.
If we don’t have a ground plane, the ripple will last longer and may influence other circuits nearby.

After making efforts in a period, I finally finish my PCB design. Next step is releasing them to factory for production. To be honest, I don’t want any mistake on my file which may interrupt further prodution process. So what points should I pay attention when I double-check my design?
My project have gone through from design, prototype to mass production after lots of discussion and adjustment. Now the manufacturer are making our products in their product lines. And I would like to know is there any differences between the prototypes in my hand now and the final products output by the manufacturer?
Some ICs have their pins labelled only with numerical values and some use alphanumeric labels. I want to know what is the correct naming term for these cases.
Is it ok to call all the chips with alphanumeric labels BGA (ball grid array)? And for chips with only numeric pin labels the chip should be called DIL (dual in line)?
More and more companies are turning to outsourcing PCB design services, especially those lacking PCB expertise and newly established companies, because designing a qualified printed
People expect electronic products to be rich in functions, but also require them to be small and portable, which brings new challenges to circuit board
The printed circuit board design is based on the circuit schematic and implements the functions required by the circuit designer. Printed circuit board design also
