Electronic parts on PCB generally contain lead and other sulfides. In the past decades, many manufacturers have said that they will not use electronic components containing lead, but it is not credible and possible. Lead is an important material in electronic components. It is practical to reduce lead but impossible to eliminate it.

My EDA software (PCAD, but I guess others do this too) adds thermal reliefs on vias in a copper pour. What’s the use? Vias aren’t soldered.
Invio il mio progetto PCB al produttore per il prototipo, ma rimandano indietro campioni di PCB deviati con ulteriori zig-zag. Perché ci sono delle linee a zig-zag su di esso?? Riduzione delle interferenze?
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?
