Why can t the wire diameter be too thick when designing a PCB?

In this case, if it is too coarse, in this case, the power will be different, so there will be certain safety hazards in use, so there will be such a situation.

When designing, if the path is too thick, it will obscure many elements, so that we do not have a complete grasp of the content of the whole image.

The purpose of making a PCB is to make things small, and if it does not affect the main performance, it is not recommended to thicken the line and wear the line indiscriminately.

First, select the line modification tool on the left, then right-click to select the trace you want to modify, and there is Change Trace Style in the pop-up menu to modify the line width.

The designer's wire diameter should not be too thick, if it is too thick, it will affect the overall appearance, so it is not good.

If the cash is too thick when the PCD is designed, it will lead to a visual perception of the whole, which is not too beautiful, so it should not be too thick.

The reason why you can't be too coarse is because if it's too coarse, there is no place to put it, and it's because of this reason.

When setting this one, its cash should not be too coarse and too coarse, which will cause him to react to the process, and the work performance is greatly reduced.

If it's too thick, the first one doesn't look good, and the second one is complicated to pack.

The main thing is that it has been affected by the installation space.

Hello, if it's too thick, then he won't be able to pass through that hole, and then there will be obstacles to its operation.

I said that I was too happy, and the product I drew was not good-looking.

1. If it is too thick, it is inconvenient to route the line.

2. If it is too thick, it will cause the circuit board to be too large.

The reason why the PC was designated by the designer was not able to look up on the day of the attitude.,To occupy the proportion should be a large job of the person is not good.。

Because if the pipe diameter is too thick, one is not beautiful, and the other is not convenient to replace when it is replaced.

Why can't it be too coarse? If the wire design is too thick, it will hinder its connection within a certain range, and too thick is not good.

First, select the line modification tool on the left, then right-click to select the trace you want to modify, and there is Change Trace Style in the pop-up menu to modify the line width.

High-speed PCB design and EMC training.

The difference is not much, of course, the wire diameter is wider than the aperture is better. In practical applications, especially for high-density boards, the line width is generally smaller than the aperture, which is required for wiring space.

It doesn't matter. The key is the processing capacity of the factory.

For example, the minimum line width and line spacing, the minimum hole, etc. As long as the factory can do it, you can design it however you want.

Consider the coupling capacitance and resistance (the relationship between the width of the trace and the inner diameter of the via); Look at the accuracy of the PCB processing factory.

The right requirements, the line width should be better!

It should be the same size when you want to draw, but there will be errors when processing. At this time, it is up to you to set the range of cutting tolerances.

There is a line width setting in the rule, the default maximum line width is 10mil, and you set it to 20mil to violate this rule, so it will report an error. However, this item is only for electrical connection lines, after you tick the keepout item, this line does not belong to the electrical connection line, so there is no error if you tick it.

These two parameters are based on power, and the line spacing is based on frequency.

Usually, 12mil is selected for wire diameter and spacing, and 10mil is selected for vias

Generally, the signal is 15mil, and the vias are 23mil and 35mil, and the light gun is not easy to find, and it is too expensive.

The jumper is to jump directly with the wire, and the wire diameter is generally selected according to the current to be passed on the line.

Generally, when drawing single-sided circuit boards, wires and flying wires are used. That is to say, when the line cannot go through, in this case, you can put two vias, and the length of the wire is defined by yourself, and it is best to define the same flying wire distance for a board. If it is patched on one side.

You can use a resistor of 0 ohms to span 0805 for the smaller one and 1206 for the larger one

Reference 2, "Death and life are broad, and the son is happy; Holding the hand of the son, growing old with the son" is a sad poem, but its attitude towards life is so affirmative. I don't like Zhuangli. I like tragedy, I prefer desolation and heroism just power, no beauty, and seems to lack humanity.

Sadness is like the red and green color scheme, which is a strong contrast. ——From Zhang Ailing's essay "My Own Article".

Below 24V, you don't have to think too much, you have to use ordinary wires, of course, high-power ones such as motors use a better wire. I don't know about high power.
