What are some basic EE or electroic engineer designer basics please
1.) Seperate the power supply from other boards
so if the power supply components short or open u can easily replace
it with another wall wart easier to troubleshoot when its seperated
2.) Don't mix power supply voltages for digital components and analog components
they should be seperated power supply lines
(can cause ticking or switching off/on sounds bleeding into the analog signals)
The digital components should be "isolated" from the analog components for
power supply voltages
3.) What components that are really close together can use noise or create
oscillation sounds when to close together like stray capacitance?
Because when doing the schematic of the board your going to make in
electronic workbench or some type of software it will do tracemaking
for the boards thats sent to the CNC machine shop to press the boards
When making putting the components/parts and soldering to the boards
when made sometimes if components/parts are to close together can
create oscillations or noises in the real world that u didn't know when proto
typing it on a breadboard or simulating it in software it didn't happen but
when u make the real board with components solder to it causes oscillation
and noises from certain components/parts to close together
Which components/parts when close together would cause oscillations or
noises please?
Shielding:
4.) When making a prototype on a breadboard of the circuit for a R&D department
how do u shield the circuit?
When making the board in real life there is mostly a shielding problem
what are some basic EE shielding tricks to do in general for basic digital and
analog circuits?
5.) EE engineers focus on Shielding and ground loops
What are some basic EE ground loop trick to do in general for basic digital and
analog circuits?
6.) What others do u guys know about please that can add to my list?
