Posso fazer um PCB sem plano de aterramento?

Recently we are developing a portable device which should be very tiny and light. In terms of PCB design, I am thinking whether it is a good idea to exclude ground plane to minimize the product size.

It depends. For high-speed logic or RF circuits, a ground plane is necessary. For others, ground or power plane is not required.

You should, Contudo,

Make sure that the traces are as wide as possible, particularly for the power, ground or other high-current connections.
Ensure fatter traces are more reliable.

Is conformal coating necessary onto the PCB assembly?

I noticed that most PCB and components on it are conformal coating. Is that a necessary process for all the PCB in other field? What are they for?

How can I make electrical connections over v-score line?

I was thinking how to make electrical connections over v-score line year ago and I was thinking that there is no solution. Alguma dica?

Como você monta componentes eletrônicos no chassi de um veículo com segurança?

I want to implement a control system I designed for a light electric motorbike. I would like to mount it as professionally as possible on the chassis. It consists of a power system pcb and a SAMC21 development board which I’ll merge later once this all works properly. I have tried screwing it directly on the aluminium chassis but have found that shocks and vibrations from the horn disturbed the system or even destroyed it upon large shocks. Is there a specific way car and motorcycle manufacturers mount their electronics to make their system as robust as possible?
