PCB copper balance design and layout

How to understand PCB Copper balance in PCB fabrication

A symmetric copper distribution (copper balance) on the circuit board is very important, because asymmetric copperleads to bow and twist effects in PCB fabrication process,and finally will affect the soldering quality of components in PCB assembly process. This warping of the form is caused by thermal loads in the circuit board, such as those caused … Continued
