Through-hole PCB Assembly Service

JHYPCB is a trusted PCB assembly manufacturer, providing one-stop turnkey PCB assembly services, including surface mount technology, through-hole PCB assembly, and mixed technology PCB assembly.

Best Through Hole PCB Assembly Service

Through-hole has to do with having components assembled to a printed circuit board. There is something you need to understand about through hole PCB assembly service. This is the fact that they are very technical. Thus, they require the expertise of a reliable and trusted company with proven track records to deliver. In this case, components’ pins get plugged from the PCBs’ top sides into the through-holes. Another way to look at this service is that PTHs (pin through holes) are inserted through the holes which have been drilled into PCBs.

Although this standard or practice became common within the industry during the 40s, it is still very much popular. In other words, it is still relevant as electronic manufacturers are still making use of it till this day. In the initial period when it was used, companies tried to cover through hole assembly with handly plugin as well as solder. In other words, the process was a little bit manual as compared to how it is done today. Many companies around like JingHongYi PCB (HK) Co., Limited have all the necessary machines to automate it.

Looking For The Best Through Hole PCB Assembly Suppliers?

Through Hole PCB Assembly Service

It is true that there are lots of through hole PCB assembly suppliers you can choose from. However, always remember that not every company can render such a complicated service without any complaint. Our experience and knowledge in rendering through hole PCB assembly service is second to none. This is due to how we have successfully handled different projects in the past.

Through hole technologies are of two major types. These are axial and radial. In the case of axial through hole technology, the metal wire is going to have the component’s body crossed axially. In this instance, two pins that are long will be leading out from both sides. Parts like these don’t require much axial spacing. This is what we usually recommended to clients that are requesting for flat assembly.

Radial through hold technology is all about 2pins that are short leading out from one side of a particular component. The component in this case, will be standing out from the board’s surface. In most cases, we recommend this one for clients that want dense assembly. It should be noted that these two through hold assemblies have their pros and cons. Based on the project you are planning to execute, be rest assured that our experts will always make the best recommendations. For instance, when it comes to snugness to the circuit board, axial lead components are very popular. On the other hand, surface areas that are less require radial lead components.

Through-hole Components

In most cases, axial lead components and configuration are usually available in the form of LEDs (light-emitting diodes), fuses, electrolytic capacitors, and carbon resistors. There are very few through hole PCB assembly suppliers that understand all of these processes like we do at JHYPCB. Therefore, always expect nothing but the very best of through hole PCB assembly services from our experts.

Why Hire The Services of Through Hole PCB Assembly Manufacturers?

The truth is there are lots of benefits that through hole PCB assembly manufacturers can enable you experience firsthand.

For instance, it has been discovered that with through hold technology, there is a much stronger bond between the board and components. Are you trying to handle any of those heavy-duty projects? Do you know that due to this advantage, through-hole is the most recommended option? For instance, when the bond is very strong, there is a very good chance for such components to cope with mechanical stress.

The same can also be said about high voltage and high power. Through-hole technology is perfect for electrolytic capacitors, semi-conductors, connectors, and transformers. Since components are running through the board, it is easier for them to cope with environmental stress. This is the primary reason why through-hole technology is the perfect option when military products are being built. Again, it is important to note that through-hole circuit boards can be easily tested. They are great for prototypes due to their nature as they can be easily swapped out.

Having seen all of these, it is clear that JingHongYi PCB (HK) Co., Limited is the best company around when it comes to rendering the best services related to through hole PCB assembly services. Based on the nature of your project, our experts are going to give out the best professional advice. Be rest assured that you are in safe hands.

THT Assembly

Frequently Asked Questions.

Through-hole PCB Assembly is an early popular through-hole technology in the electronic assembly industry, or THT for short. Although SMT is the most widely used PCB assembly process today, through-hole assembly is still popular. It is often used to mount larger electronic components such as transformers, connectors, semiconductors and electrolytic capacitors onto circuit boards. Thread preformed components through pre-drilled holes and solder them to the board by hand or automated processes. Through-hole assembly is often used when components need to be mounted on both sides of the board.

The types of PCB assembly are as follows:


  • Single Sided THT Assembly
  • Single-sided SMT Assembly
  • Single-sided Mixed Assembly
  • Double Sided SMT Assembly

The cost of through-hole PCB assembly depends on a variety of factors, including through-hole PCB assembly part type, order quantity, special processes, and lead time.

JHYPCB provides low-cost PCB assembly services. Please send your PCB assembly inquiry and we will provide you with high quality and low-cost PCB assembly services.

Surface mount technology and through-hole technology assembly are two types of PCB assembly. Through-hole technology assembly has the following advantages:

  • Highly Reliable
  • Easier for Prototyping
  • Higher Heat Tolerance
  • Superior Power Handling
  • Stronger Physical Connections and Durability
  • Manual adjustments can be made easily

There are two types of components for through-hole PCB assembly:

1. Radial Leaded Components

Radial lead components take up less space. Radial lead components have leads that extend from the body of the component, typically, perpendicular to the board.

2. Axial Leaded Components

Axial leads parts run in a straight line from one end of the component to the other, forming two terminals. The component ends up being closer and flatter on the board.

Yes. We can provide you with high reliability one-stop PCB assembly services, including PCB manufacturing, component procurement, assembly and testing services.
