Muito importante. Uma vez que o sinal chega ao plano de terra do circuito, haverá uma onda. A ondulação pode se espalhar e influenciar o sinal em outros circuitos.
Se não tivermos um plano terrestre, a ondulação durará mais e poderá influenciar outros circuitos próximos.

#PCB Design
I am a buyer in a telecom company. Recentemente, an important order of SMT PCBA is delayed due to insophiscated production of a supplier. I am thinking about replace it and just very puzzled about how did their SMT pad fall off easily when soldering the PCB boards. That slows down the whole process.
Se eu quiser projetar uma PCB com o máximo de imunidade a ruídos possível, devo deixar de fora os pontos de teste? Os pontos de teste de PCB podem ser uma fonte de ruído??
Tente consertar o esfigmomanômetro eletrônico agora. Parece que os fios caíram do PCB flexível, deixando rastro lá. Como faço para soldá-los ao flex-PCB?
