Need of Enclosure for a Custom Circuit Board

When building a custom plastic enclosure electronic circuit, you usually need to house and enclose it in an enclosure. If youíre using the PCB only with a microcontroller, soldering the leads onto the copper may be all that needs to be done. However, if you want to use this PCB with other components and additional circuitry, it will eventually need power. You will have more parts of surface-mount technology (SMT) on your hands, requiring extra attention and some enclosure for heat resistance.

A primary enclosure will have PCB spacers, terminal strips, and binding posts soldered to the PCB. The PCB is then set into a panel and held in place by screws. Can make the board out of wood if you like, or you can use plastic if it is used for something mechanical. Plastic is more cost-effective and lightweight as well as sturdy.

Why Use Enclosure For a Custom Circuit Board?

1. Heat dissipation

A PCB can reach a high temperature quickly, especially if it needs to draw a lot of power. Since it is flat and exposed to air, heat doesnít dissipate fast enough from heat sinks. That may lead to overheating or even burning out of the circuitry within.

2. Protection from outside elements

Sometimes, liquid or even water vapor can seep through the case and short or burn out the wiring. Itís also possible for a shock of some kind to damage it, which is critical for safety reasons. The Enclosure For a Custom Circuit Board protects the circuit board from experiencing any damage from water and dust.

3. Easier to work with

Sometimes, itís easier to work with the enclosure rather than soldering the circuit board directly onto the plastic. It allows you to place components and add wires without worrying about shorting them together or accidentally messing up parts on your circuit board.

4. Fewer parts to work with

There are fewer components on the PCB, which may decrease the number of soldering points and the complexity of your circuit board, which means itís easier to work with and not as time-consuming.

5. Easier to create designs on a PCB layer at a time

When working on a custom plastic circuit design, itís usually easier to make changes, fix mistakes, or add features when you can see what they will look like against a flat surface.

How to Plan for an Enclosure for the Circuit Board?

Planning out the circuit board before you design the enclosure is always a good idea. The first thing to do is to decide what components and additional circuitry you wish to use on your PCB and whether or not you will use power from it. These factors will determine which enclosure panel you need. If you need input from your circuit, then an engraved forum is appropriate, while a printed panel will work best if the power output is necessary.

Since enclosure panels are usually used to separate the main circuit board from the case, they are designed to be thin and have enough room for a PCB header. If you have many components that need to be on the PCB, then you may want to use an extension panel.


If you plan on building a Enclosure For a Custom Circuit Board, you should always consider using an enclosure. It will help to protect the circuitry from outside elements and minimize heat buildup. Fortunately, there are many ways to plan for one, and the techniques used often depend upon the number of components used on your circuit. Itís important to consider input and output options as well as whether or not you need power or not. Tool-Less is where you can find the perfect enclosure for your custom circuit board.
