Everything PCB !

There are more and more electronic equipments of small size as technology development, and they all need small-size PCB to support normal operation. And what are the applications of small PCB? How to make PCB as small as possible? In this passage, we are talking about the topic please follow us to learn more about the professional knowledge.

What are the applications of small PCB?

The size of the board depends on your design. You can use computer-aided design software to create the circuit layout. That way you can easily reduce the size of the board. More often than not, the spaces between two electrical conducting paths are 0.006” or smaller.

The dimensions of the printed circuit board are based on the circuitry, as well as the enclosure that will house the PCB. It will also determine the heat sinks and fixed components of the circuit. With the use of the software, you can easily reduce the size of the board. You should consult with the manufacturer to determine the smallest size they can make.

The size of the circuit board depends on the available space of the enclosure. If you are designing a tiny gadget, then you need to use small circuit boards. But keep in mind that when you create a small PCB design, it will have small components as well. That could mean soldering them with a very fine tip soldering iron and a microscope or close-up glasses, especially if the holes have tight clearances.

What are the tips to make small PCB?

When designing a circuit, you should consider factors such as minimum trace width, minimum silkscreen width and text size, SMT minimum solder mask width, minimum solder mask clearance, minimum trace/pads/vias space, and the drilling and finish hole. These factors will determine the minimum size of the circuit board.

Always consider blind and buried vias carefully because they can create a significant impact on your design as well as engineering your PCB to be as small as possible. Vias connect traces between your board layers, and traditional options will decrease the amount of routing space that’s available on any board.

To keep routing space maximized and to avoid a larger board size, we recommend you look to alternatives. Blind vias connect external and internal layers with minimal spacing. Buried vias can connect multiple internal layers, but they do not reach out to an external layer. This limits the overall space requirement and can give you a more stable product.

You should also consider the spacing between the components. Making them too close with each other might not leave room for the routing of the traces. The more pins that the component has, the more space it will require. Proper spacing will also make it easier to solder the components on the circuit board.

In the same vein, components should stick to a general standard pin numbering design so everything is orientated equally, reducing the likelihood of mistakes during inspections and soldering. This can limit manufacturing concerns while helping you keep everything in mind as you reduce size.

Our expert engineers can also help you determine the proper width of lines based on the current used in your application. Larger width lines may take up more space, but will reduce the heat on your PCB relative to dissipation. Size lines based on current and keep your small PCBs running smoothly without the need for additional cooling support.
