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?

For prototype devices (which should last several months and are OK to fail occasionally), it is usually enough to mount the PCB on rubber inserts instead of bare screws). This greatly reduces peak accelerations your PCB sees, while keeping your prototype accessible and requiring minimum design changes.

For commercial products which should last 10 years or more, you want something more robust. I have seen automotive electronics where parts are assembled (or even the whole device is potted) with RTV silicone, which greatly helps with both mechanical sturdiness and heat transfer.

Por que meu PCB Bluetooth não consegue emparelhar com o Android 7.1 versão, mas funciona corretamente com o iphone?

It’s detecting equipment, Bluetooth emergency alarm. Mobile application for activation button via Bluetooth can not work properly on Android 7.1. If i use iPhone all is ok. Por que?

Por que o IC está no Digikey 5 vezes caro do que placa com o mesmo IC no Alibaba?

I am a project procurement a for telecom device. When I compared the unit price of the same IC between Digikey and Alibaba and find Digikey one is much more expensive. Por que?

Why is the PCB part number traditionally on a copper layer?

I notice that each design file from the supplier contains part number. It seems that it become a common habit in PCB design field. Just be curious about the reason.
