Absolutely! PCB Layout and routing have great influence on product life, stability and EMC, which is the point that we should pay more attention to.
For one thing, we can say, no matter how perfect your circuit design is, as long as the PCB Layout is unreasonable, it must have extremely bad influence to the performance of PCB. The worst situation is that the product can’t work as normal. It’s obviously like a horrible disaster.
For another thing, if the PCB Layout designer knows well enough about circuit design, he or she will definitely help the circuit designer find and correct some potential problems of the circuit board. That would be an additional benefit for team work.
