What You Need to Know About PCB Heater


If you’re a DIYer or someone who likes to tear apart old electronics, you’ve probably come across a part called the “PCB heater.” It looks like a resistor, but it’s not. What is it and its purpose?

The purpose of a PCB heater is to prevent components from overheating and failing. There are many different types of PCB heaters, but they all have the same basic design and function.

If you don’t know what you’re doing, a PCB heater can cause a lot of headaches and damage to your device! That’s why it’s so important to understand how PCB heaters work and how to use them properly.

What is a PCB Heater?

PCB heaters are a type of electrical heating element that is used to keep the temperature of printed circuit boards (PCBs) at an optimal level. They are used in many different types of applications, including the manufacturing, testing, and repair of PCBs.

These PCB heaters are used to keep the circuit board warm during the soldering process so that components can be easily attached. They are also used to keep the temperature of the circuit board steady while it cools. PCB heaters come in many different shapes and sizes, depending on their application.

These PCB heaters are placed near the components that need to be heated up—like transistors or integrated circuits (ICs)—and then they heat up those components through their resistance property.

How Does a PCB Heater Work?

A PCB heater works by heating up the plastic circuit board (PCB) to a temperature that makes it conductive and able to transmit electricity. The PCB heater is typically connected in parallel with other components, such as resistors and capacitors, in order to stabilize the voltage output of the circuit.

The PCB heater itself consists of a coiled wire that heats up when current flows through it. This current is usually provided by a power supply. The heat generated by this process causes the PCB’s plastic substrate to become more conductive, which allows electricity to flow through its surface more easily.

Two Types of PCB Heaters

PCB heaters are an essential part of the circuit board, and they help to make sure that the board can operate at a certain temperature. There are two main types of PCB heaters: convection and infrared.

Convection PCB Heater

Convection PCB Heater


Uses air to transfer heat instead of electromagnetic radiation. Convection heaters are typically used in applications where the temperature needs to be uniform across the entire PCB surface, such as when creating printed circuit boards.

The main advantage of convection heaters is that they are less expensive to manufacture than other types of PCB heaters. They also require less electricity and generate less heat than other types of PCB heaters.

The convective heat transfer coefficient is high, which means that heat transfer is fast, and it can ensure that the temperature difference between parts can be reduced as much as possible. This also helps to reduce thermal stress on the products during production and use.

Infrared PCB Heater

Infrared PCB Heater


These heaters use electromagnetic radiation to transfer heat. They can be used as either radiant or convective heaters, depending on the application.

The advantage of infrared heaters is that they can be used to heat up an entire PCB, not just a single component. This means that you can use these types of heaters to speed up the soldering process by quickly heating up your entire board at once.

However, there are some disadvantages to infrared heaters as well. They tend to be less precise than other types of PCB heaters and they don’t focus the heat on a specific area or component on the board; they simply spread it out evenly over the entire surface of your PCB.

Two Parts of PCB Heater

In the world of electronics, a PCB heater is a component that helps to keep your products cool. The two main parts of a PCB heater are the resistor and the heat sink.

Two Parts of PCB Heater

Parts of the PCB Heater


A component that will allow the PCB heater to work properly. It also acts as a current limiter, which means that it will prevent the current from flowing too fast through the device and causing damage.

The resistor is made from a conductor, such as copper or aluminum, and it has a specific resistance. The amount of current that flows through the conductor depends on its resistance.

The resistor is used to limit the current flowing through your PCB heater because if you don’t have one, the heater may burn out quickly.

Heat Sink

It is a large, flat surface that’s made of metal and has a huge heat capacity. It is used to dissipate the heat generated by electronic components, such as transistors, diodes, and integrated circuits.

The heat generated by these components is conducted to the metal case or aluminum plate, which is connected by screws to the sink. It is often used in conjunction with a fan to increase the amount of airflow around the circuit board and its components.

What to Check When Having a PCB Heater?

Have you ever wondered what to check when buying a PCB Heater?

In this list, we will be covering the different parts of a PCB Heater. We will talk about what each part does and why it is important.

PCB Heater Design

This is a key part of the PCB assembly process. You need to ensure that your PCB heaters are designed in such a way that they can withstand pressure, temperature, and other factors that might affect them during the assembly process.

When you have a PCB heater, you need to know the design. The design is one of the most important factors to consider when you are buying a PCB heater because it determines how well your product will work.

If you choose a poorly designed PCB heater, then it won’t be able to heat up as much as other models, and this can lead to problems with your product. You should look at the size of the PCB heater and see if it is large enough for what you need or if it is too small, which may not be able to provide enough heat for your product.

PCB Trace Heater

First of all, you need to know that the PCB heater needs to be able to withstand the mechanical stresses that it will be subjected to during operation.

You also need to know that the PCB trace heater should be able to tolerate the temperature at that it will be used.

The most important thing is that the PCB trace heater should be able to withstand any environmental conditions that it will be exposed to during its operation.

To be sure that your PCB Heater is working properly, you also need to check the PCB Bed Heater. You might not know what it looks like, but it’s a component of the PCB Heater that is often overlooked by people who are not familiar with this type of equipment.

The purpose of a PCB Bed Heater is to keep your PCBs warm enough so they can be manufactured more quickly and easily. It’s used in conjunction with other components of PCBA manufacturing systems. You want to make sure everything is working well together. You’ll need to check out the PCB Bed Heater as well as other aspects of your equipment.

How to Manufacture a PCB Heater for Beginners?

PCB heaters are used to heat printed circuit boards. They can be used to transfer heat from one place to another, or they can be used as a heating element in an electrical device. They are made from copper and other metals, which are often plated with nickel or silver for better efficiency.

The good news is that PCB heaters can be manufactured! Here are some steps in manufacturing them safely:

Design the PCB

PCB Design

Design the PCB

First, you need to design the PCB or printed circuit board. This is the board that will hold your components and allows them to be connected together. If you’re new to electronics and PCB design, you might want to start with a breadboard first. A breadboard is a lot like what it sounds like: a board with holes in it where you can plug in wires or components so they can be connected together easily. You can get these from any electronics store or online.

Once you have your breadboard, you can test out your circuit before designing it on paper. To do this, place a resistor between the positive power rail (usually red) and ground (usually black). Then connect one end of an LED to each side of the resistor. This will let you see if everything is working before moving on to creating a layout for your PCB design software like Eagle Cadsoft’s Schematic Editor or Altium Designer’s Schematic Editor!

Create the PCB

PCB Manufacturing

Create the PCB

The second step to creating a PCB heater is to create the PCB. To do this, you will need a blank circuit board and some copper wire.

You can find both of these items at your local hardware store or online. The copper wire is typically sold as solid core or stranded wire. You’ll want to use solid core wire because it’s easier to work with and less likely to bend over time. You’ll also want to pick up some solder and flux.

If you’d like, you can use an etching solution to remove the protective coating from your PCB before soldering it together. This will make it easier for heat transfer later on in the process.

Once you’ve created your PCB, cut out holes where you want your heaters placed on the board. Then put some solder paste into each hole with a toothpick or screwdriver tip. Let this dry for about 15 minutes before moving on with the next step!

Drill & Solder the PCB

Drill & Solder the PCB

This is a fairly easy process, but it can be tricky at first. First, you should use a drill bit that’s slightly smaller than your screw or bolt that will be used to hold the PCB in place. Make sure to drill your holes as straight as possible without going in at an angle. If you’re using a machine to do this, this shouldn’t be an issue unless your machine isn’t properly calibrated.

Next, take some time to study the layout of your PCB before soldering anything down. You don’t want any wires or components touching each other and causing shorts or other problems later on! Finally, once everything is lined up correctly and firmly secured in place with nuts and bolts. Go ahead and solder everything together!

Look for an Appropriate Power Source

Appropriate Power Source

Look for an Appropriate Power Source

The last step in making a PCB heater is finding the right power source. There are several options, but the best choice depends on your needs and the amount of money that you want to spend on your project.

The most basic option is to use a battery, such as those found in AA batteries or rechargeable batteries. The downside of this method is that it requires constant replacement of batteries, which can be expensive over time. In addition, batteries tend to be less reliable than other options. They are prone to leaking or exploding if they are not handled properly.

Another option is to use an AC adapter that plugs directly into an outlet. This type of equipment tends to be more durable than batteries. It can still be problematic if the user isn’t careful with how they handle their heating device.

A third option for powering PCB heaters is using a DC power supply instead of an AC one. This will allow users to take advantage of both types of electricity without having any issues with safety or reliability (as long as they use them correctly).


These days, PCB heaters are the common type of heating element included in normal electronic devices. It is important to understand these PCB heater boards and how they work. You can make an informed decision about choosing and applying these boards to a more complex project.
