I drew an 86 control board myself, and I want some wiring advice from you guys [Copy link]

 

The main parts are the screen and audio. Can someone help me see how the wiring can be optimized? It seems that the wiring is not smooth and the power supply is too far away.

There is no problem with the PCB. The vias in the copper cladding are too dense. I'd better print a version to see if there is any problem with the actual product.

Not bad~

Is there a teardrop shape where the trace and pad meet?

It is useless for a PCB to look beautiful. A good board is one that can realize its functions.

The painting is good, so: I am asking for advice and showing off at the same time.

It's not complicated, there's nothing wrong with it, and the frequency is not high.

It's pretty. It does look neat when there are more lines at 45 degrees.

In fact, there is still a little space available. You might as well add a test pad to make debugging more convenient.

Yes, add it. It is indeed more convenient.

Azuma Simeng posted on 2023-9-21 17:50 Is there a point where the trace and pad are connected that should be made into a teardrop?

Well, it looks better.

That's not the case, I just don't know for sure. Let's have a look and exchange ideas. I feel that the line is too long and has become a loop.

Well, I mainly want to ask whether the layout is reasonable. I feel that the most difficult thing to deal with is the power line, which is pulled everywhere. It is very comfortable to see the boards drawn by other big guys. The copper-clad side is the analog ground of the audio. I think it will have better contact. Haha, anyway, it doesn't cost money.

Thank you, but I don't know if it's OK to extend the power supply so long. Is there a better way?

Yes, I'm new to it now, and I'm not good enough to draw at high speed.

It is said that the cost of 86 industrial control board can be 4 layers, right?

I have obsessive compulsive disorder, so achieving functionality is definitely my top priority, but if I want something to look good, I feel comfortable looking at the drawings of other masters on the forum.

ardtek published on 2023-9-22 09:05 It is said that the cost of 86 industrial control board can be allowed by 4-layer board, right?

The price is nothing, I just use this for training

It should be okay if it is too long. Pay attention to the order in which the power supply supplies power to other chips.
