Through Hole PCB Assembly Services

Through hole PCB assembly services involve inserting through-hole components into the pre-drilled copper-filled through-holes of the PCB. Electrical and mechanical connections are achieved through soldering, usually wave soldering or manual soldering.

Through-Hole Assembly Advantages

What Are the Features of Through-Hole Assembly, Compared to SMT?

Although SMT is the mainstream, through hole assembly still cannot be replaced in scenarios where high reliability and prototype debugging are required. The two are often used together to leverage their respective advantages.

01

High Mechanical Reliability

Through-hole components form stronger mechanical bonding, with better vibration, shock, and thermal cycling resistance compared to SMT. This makes through hole assembly suitable for high-stress applications such as military electronics, automotive electronics, and power connectors.

02

Easy Manual Soldering and Maintenance

Through-hole components usually have larger bodies and thicker pins, making them suitable for prototype development, testing, and rework. SMT components are much smaller and more difficult to handle manually.

03

High-Power Device Support

Through-hole components can handle higher currents due to larger wire cross-sections and better heat dissipation. Common examples include transformers, large capacitors, and power-related components.

Application Scenarios

When Is Through Hole PCB Assembly Recommended?

  • PCB projects with large plug-in components or connectors.
  • High-current and high-voltage electronic products.
  • Prototype development, testing, and engineering sample production.
  • Products that require stronger solder joints and mechanical support.
  • Mixed PCB assembly projects using both SMT and through-hole components.
