What Is Through Hole PCB Assembly?
Through-hole PCB assembly is conducted through THT(Through-Hole Technology). Here, through-board components with leads are inserted into the PCB surface via drilled holes. These leads are soldered manually or by using the wave soldering method.
Through-hole PCB assembly is highly applicable where impressive robustness is required. This process allows the leads to go through the PCB holes. That’s why PCB can put up with huge mechanical and thermal stress.
Through-hole PCB Assembly
Besides, THT promotes layer bonding of PCBs. This technology can resist corrosion, high acceleration, etc. So, electronic devices which incorporate through-hole PCB assembly render their service for a long time.
What Are The Advantages Of Through Hole PCB Assembly?
Through-hole PCB assembly offers numerous advantages in versatile applications. So, it has become the leading method of PCB assembly nowadays.
The most noteworthy benefits of through-hole PCB assembly are explained here for you.
Through-hole PCB assembly provides a higher resistance in opposition to mechanical pressure. It makes the attachment between PCB layers strong. This property obstructs the breakage of electric circuits.
Highly Durable Through-hole PCB Assembly
Again, thorough-hole components like chip capacitors don’t get affected by vibration because of having lead wires. That’s why through-hole PCB components are highly durable.
Effective temperature resistance is another advantage of through-hole PCB assembly. Through-hole PCB components operate in a wide range of temperatures. But, they don’t compromise the performance of through-hole PCB assembly.
The components used in through-hole PCB assembly last for a long period. They can function amidst the extreme thermal state, stress, etc with great efficiency. So, through-hole PCB assembly provides superior longevity.
Through-hole PCB assembly renders commendable functionality. Here, through-hole PCB components can be interchanged easily. So they are compatible with PCB prototype applications. You can test these components without any complications.
Through-hole PCB assembly is highly applicable in the aerospace industry and defense technology due to its high robustness. It also resists the frictional loss of through-hole PCB components. All of these properties enhance the functionality of through-hole PCB assembly
Through-hole PCB components operate at high power levels. That’s why solder joints can carry high current loads in through-hole PCB assembly.
The components used in through-hole PCB assembly combine through-hole pins and SMPs(Surface Mount Pads). Such as the mounting pins of the connectors are through-hole where the signal pins are surface mount.
The amalgamation of these impressive advantages turns through-hole PCB assembly into a widely used process.
What Are The Disadvantages Of Through Hole PCB Assembly?
Despite having tremendous benefits, through-hole PCB assembly also has some limitations. Such as:
- The drilling of holes in through-hole PCB assembly is costly and lengthy.

What Techniques Are Applied In Through Hole PCB Assembly?
Applying the most effective technique in through-hole PCB assembly is very important. There are two most applicable assembly techniques available for through-hole PCB assembly.
- Manual through-hole PCB assembly
- Automated through-hole PCB assembly
You have to choose your required technique concerning the application type, production scale, cost, time length, efficiency, and so on. You have an opportunity of doing a mash-up between these two techniques.
This is called the mixed through-hole PCB assembly technology. We provide a worthwhile through-hole PCB assembly by applying the best technique required for your PCB projects.
What Is Manual Through Hole PCB Assembly?
Manual through-hole PCB assembly is a common technique for PCB assembly. Here, you have to place the through-hole components on the PCB surface and solder them. You can easily perform these tasks manually.
Again, you can replace through-hole PCB components efficiently. through-hole PCB assembly consists of some consecutive steps. You need to deliver the PCB to another section to perform the next step.
The manual technique is effective for small-scale PCB production. This is actually a designer-dependent assembly technique. The designer uses tweezers to pick and place through-hole components.
Manual Through-hole PCB Assembly
The performance testing of manual through-hole PCB assembly is very lengthy. There is a higher chance of inaccuracy. Again, manual through-hole PCB assembly delays your production in the case of soldering problems.
But, this technique saves your money. Despite having some drawbacks, the manual technique is applied in through-hole PCB assembly. Watch the following video:
What Is Automated Through Hole PCB Assembly?
Automated through-hole PCB assembly is the most reliable technique for PCB. You can be free from the sufferings of time delay, poor production value, etc. Here the placement of components, soldering, inspection, etc are conducted without any human input.
This technique is more reliable than manual through-hole PCB assembly. You can apply automated through-hole PCB assembly in both small and large-scale PCB productions. You can get better performance from your devices through automated through-hole PCB assembly.
Automated Through-hole PCB Assembly
There are so many effective automated testing methods available. Such as automated optical inspection, X-ray inspection, etc. These inspections take less time to identify defects and provide higher accuracy.
Automated through-hole PCB assembly is costly. So, it has fewer uses in low-volume PCB applications.

Through-hole PCB assembly consists of multiple steps. Each step requires specific types of equipment to operate the assembly. Now, have a look at the necessary equipment used in different steps of through-hole PCB assembly.
Using solder paste
This is usually the first step of through-hole PCB assembly. You need to apply solder paste on the PCB surface to attach the components properly. Here, you need to use the following machines-
- Solder paste printing machine
- Solder paste inspection machine.
These types of equipment make the paste application perfect.
Placement of components
In through-hole PCB assembly, components placing is a crucial subject. In this phase, a machine is used to put dots of glue on PCB. You need to place the components in those locations.
Through-hole PCB Assembly Equipments
Besides, a pick and place machine places the through-hole components on the specific spots of PCB.
Through-hole PCB assembly uses a wave soldering machine to weld the PCB surface. This machine supplies a solder wave to weld the through-hole components lead on the other side of PCB.
This step is the last but not the least. A proper inspection ensures a top-class through-hole PCB assembly. Usually, automated optical inspection is conducted through an AOI machine.

Through-hole PCB Assembly Soldering Preparation
How To Apply Soldering In The PCB With A Through Hole PCB Assembly?
You can apply two popular soldering methods in PCB with a through-hole PCB assembly. They are-
- Wave Soldering
- Through Hole Reflow(THR) Soldering
Let’s have a look at the explanation of these solderings.
This soldering technology has the widest uses. Here, through-hole components with leads go through the holes on PCB. A wave is applied on the opposite side of the PCB surface at a high temperature. This soldering wave creates a plate on that portion.
The PCB portion out of soldering should be enfolded with a protective mask. Otherwise, undesired welding at some portions of the PCB surface may occur.
Through-hole PCB Assembly Wave Soldering
Wave soldering is cheaper compared to other soldering methods in through-hole PCB assembly. This is compatible with both small-scale and large-scale productions.
Watch this video on wave soldering:
In through-hole reflow soldering, solder paste is applied to the holes. You need to control the temperature to melt this solder paste properly. It melts at more than 100⁰C and fills the PCB surface perfectly.
A proper connection is established between through-hole PCB components when the temperature decreases. THR soldering ensures high mechanical balance in through-hole PCB assembly.
But, it costs more than wave soldering. THR soldering is not reliable for low-volume through-hole PCB assembly.
What Are The Applications Of Through Hole PCB Assembly?
Through-hole PCB assembly has immense application in various industries. Its supreme reliability makes it a widely used assembly technology for PCB manufacturing.
Here, some notable applications of through-hole PCB assembly are included for you.
