Through-Hole PCB Assembly

When Through-Hole is the Right Answer

Surface-mount technology has displaced through-hole for most modern designs, but there are still applications where through-hole assembly is the only sensible choice:

High-current components: Large capacitors, transformers, and power-handling parts with mechanical lead anchoring
High-vibration environments: Automotive, aerospace, industrial machinery, where mechanical lead strength matters
Connectors and headers: Through-hole solder joints handle insertion and mating cycles that SMT cannot
Repairable assemblies: Through-hole parts are easier to replace in the field
Mixed-technology designs: Most modern boards combine SMT and through-hole; we handle both in one pass

Advantages of Through-Hole Assembly and Its Process

We provide reliable through-hole PCB assembly services because of the many benefits this technology offers.

  • Strong Mechanical Connections: Through-hole circuits create stronger mechanical bonds, making components more stable and durable.
  • High Resistance to Environmental Stress: Due to their strong bonding capability, through-hole assemblies can withstand harsh environmental conditions, vibrations, collisions, and accelerations. This is one of the key reasons why THT technology is commonly used in military and industrial equipment.

Enhanced Board Security: Through-hole assemblies offer improved board stability and secure solder connections, making them suitable for prototype development and broadband socket applications.

What is through hole PCB Assembly and what are its techniques?

In straight words, the PCB assembly which is done with the help of the through –hole boards is known as the through hole PCB assembly. There are two things that are responsible for the correct setup of the PCB assembly. They are the radial and the axial leads. The elongated box-shaped axial leads are protruded from both ends. Whereas, the radial leads come out form the parallel of the circuit board. In case of the through hole PCB assembly, the multiple lead devices can also be made. The usage of the semiconductor packages is needed for it.

Frequently Asked Questions

Yes. Wave soldering is the default for high-volume, through-hole-dominant boards. Selective soldering is used for mixed-technology boards where SMT components on the bottom side cannot survive a wave bath.

Yes. Press-fit assembly is supported. Tooling and process review happens during DFM — press-fit force, alignment, and board support are critical for joint reliability.

We support RoHS no-clean and RoHS water-wash processes, plus leaded for legacy and aerospace work. Process is selected per project requirement and documented in the build packet.

Yes, Our technicians are trained to IPC-A-610 workmanship standards for hand-soldered joints. Common for prototypes, very low-volume programs, and one-off specialty assemblies.

Through-hole is typically more expensive per joint on high-volume runs because of slower insertion and soldering. But for low-volume prototypes, the cost difference is small, and the mechanical reliability is often worth it.

What is Through Hole PCB Assembly?

Through-hole technology (THT) is a PCB assembly process where component leads are inserted into drilled holes on the PCB and soldered from the opposite side. Unlike surface mount technology, through-hole assembly creates stronger physical connections, making it ideal for heavy-duty applications and components that experience mechanical stress.

Through-hole PCB assembly is commonly used for:

  • Industrial electronics
  • Automotive systems
  • Aerospace equipment
  • Medical devices
  • Power supply systems
  • Military electronics
  • Communication equipment

This method is especially beneficial for components such as transformers, connectors, capacitors, and large semiconductors that require high durability and stable performance.
