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.

Meu software de design de PCB vem com algumas bibliotecas que incluem alguns componentes comuns, como resistores de chip e capacitores. eu notei, Contudo, que o padrão de pegada terrestre para o 0805 resistor is not identical to the 0805 capacitor. Is there a “best standard”? IPC-7351, IPC-SM-782, or what?
I am getting a PCB manufactured for a project that I am working on. One of the parts, the A4950 motor driver, has a “almofada” on the bottom, which is meant to be soldered to GND of the PCB for thermal dissipation. I was thinking about the prototyping, and I am unsure how I would go about (using a soldering iron), soldering the pad on the bottom.
I have a set of LED driving lights for motorcycle that must be wired through a ground-leg pulse width modulation dimmer. The problem is the mounting bracket for the lights is grounded, so the lamp shorts to ground through the motorcycle chassis and the PWM dimmer cant dim the lamps. How do I handle this problem?
