pcb布局设计

Are you thinking about designing a printed circuit board? PCBs are quite complicated, and you need to make sure that the layout that you choose is going to operate as well as you want it to. For this reason, we have put together some top tips for PCB design layout. Keep reading if you would like to find out more about this.

您是否正在考虑设计印刷电路板？ PCB非常复杂，您需要确保所选择的布局能够按预期运行。 因此，我们整理了一些PCB设计布局的重要技巧。 如果您想了解更多信息，请继续阅读。

Leave Enough Space

留出足够的空间

One of the most important design tips for PCB layout is that you need to make sure that you are leaving enough space between the components. While many people might think that packing components closely is the best route to take, this can cause problems further down the line. This is why we suggest leaving extra space for the wires that will spread. This way, you’ll have the perfect PCB design layout.

PCB布局最重要的设计提示之一是，您需要确保在组件之间留出足够的空间。 尽管许多人可能认为紧密包装组件是最好的选择，但是这可能会导致进一步的问题。 这就是为什么我们建议为将要散布的电线留出额外的空间。 这样，您将拥有完美的PCB设计布局。

Print Out Your Layout

打印出您的布局

Struggling to find out if your components sizes match? Our next tip is to print out your layout and compare the printed version to your actual components. Datasheets can sometimes come with errors, so it doesn’t hurt to double check the sizes in real life. If you take some time to do this, you can be sure that the sizes will match.

努力找出您的组件尺寸是否匹配？ 我们的下一个技巧是打印出您的布局并将打印的版本与您的实际组件进行比较。 数据表有时会带有错误，因此在现实生活中仔细检查大小不会有什么坏处。 如果您花一些时间来执行此操作，则可以确保大小匹配。

Think About Width Of Line

考虑线宽

When you are deciding the width of the lines in your PCB design, you should make sure that you are choosing this based on the current. If you have a larger current flowing through the lines, then you should make sure to adapt your design to suit this. There are some online calculators that you can use to help make this decision.

在确定PCB设计中的线宽时，应确保基于电流进行选择。 如果有较大的电流流过线路，则应确保适应您的设计。 您可以使用一些在线计算器来帮助做出此决定。

Talk To Your Manufacturer

与您的制造商交谈

If you spend a long time working on your PCB design project before you have spoken to a manufacturer then you might find that you come across some problems. You need to find out about any specifications that they might have that could affect the design of your project. Use their guidelines to create your design and you’ll find things a lot simpler further down the line.

如果在与制造商交谈之前花很长时间从事PCB设计项目，则可能会发现遇到一些问题。 您需要找出可能影响项目设计的任何规格。 使用他们的指南来创建您的设计，然后您会发现事情变得简单得多。

Compare Your Schematic

比较原理图

Our final tip for those who want to improve their PCB design layout is to compare the layout to the original schematic. You have spent time working on your schematic for a reason so make sure to utilise the tools that allow you to directly compare these. This way, you can be sure that your layout matches what you need for this particular project.

对于那些想要改善PCB设计布局的人来说，最后的建议是将布局与原始原理图进行比较。 由于某种原因，您花了很多时间在原理图上，因此请确保使用可以直接比较它们的工具。 这样，您可以确保布局与该特定项目所需的布局匹配。

Final Verdict

最终裁决

If you are going to be working on PCB design project in the near future, make sure to take on board all of the tips that we have given you in this article. Think about leaving enough space between your components and considering the width of your lines. You should also make sure to talk with your manufacturer about their specifications before going ahead with the project. This way you’ll have a successful design that will help to create a working PCB.

如果您打算在不久的将来从事PCB设计项目，请确保采纳我们在本文中为您提供的所有技巧。 考虑在组件之间留出足够的空间，并考虑线条的宽度。 在进行该项目之前，您还应该确保与制造商讨论其规格。 这样，您将获得成功的设计，这将有助于创建有效的PCB。
