Also referred to as thru-hole assembly, through-hole assembly is a printed circuit board (PCB) assembly method that generates strong and efficient electrical connections for high-voltage and -power applications. At Circuit Pak, Inc., we’ve been serving clients with high-quality PCB assembly services since 1983 and it all began with thru-hole assembly!

Our team utilizes various soldering techniques to provide comprehensive manufacturing solutions for PCB assemblies that necessitate through-hole technology. Learn more about the through-hole components we handle, our expert capabilities, and the benefits of through-hole technology solutions from Circuit Pak.

Supported Component Types

Through-hole assembly is ideal for creating high-voltage components and devices. In addition to high-power uses, durable through-hole components are also capable of handling high-speed applications. They form a reliable connection between a PCB and the other parts of the assembly.

Circuit Pak specializes in the population of an array of through-hole components, including but not limited to the following:

  • Connectors like plugs, jacks, and headers
  • Transistors and diodes
  • Electrolytic capacitors
  • Leaded passives like inductors, capacitors, and resistors
  • Integrated circuits like DIP and TO-CAN packages

If you have a specific component that’s not included in the list above, check with our team to see if it falls within our through-hole assembly capabilities.

Soldering Techniques

For generating dependable, strong electrical connections, our skilled soldering technicians use a variety of soldering techniques, including:

  • Wave soldering. This soldering method is ideal for creating high volumes of PCB assemblies that include several through-hole components. Our team utilizes Vectra wave soldering systems for standard through-hole assembly. The dual wave technology delivers soldered joints without defects, and we remove flux residue with deionized water using an H2O inline cleaning system.
  • Selective soldering. A precision technique, selective soldering is best for temperature-sensitive components or those with intricate designs. At Circuit Pak, we use selective soldering to produce mixed technology assemblies that are densely populated. It’s an efficient technology for pcb’s with both through-hole and surface mount components.
  • Hand soldering. This versatile soldering process is an optimal choice for low-volume production and sensitive parts.

Benefits of Through-Hole Assembly With Circuit Pak

Through-hole assembly technology at Circuit Pak delivers the following advantages:

  • Improved mechanical characteristics. A PCB assembly with through-hole components reliably delivers robust stability and strong mechanical connections while incurring minimal damage related to vibrations. A through-hole assembly resists strain better than a surface mount assembly.
  • Expanded component options. Compared to surface mount varieties, through-hole assemblies achieve greater design flexibility by offering an expansive selection of components.
  • Enhanced heat dissipation. Serving as heat sinks, through-hole component leads offer improved heat dissipation for high-power assemblies.
  • Simplified component repair. As it’s easier to take out, rework, and replace through-hole components, they’re better at facilitating assembly repair than surface mount technology.
  • Superior quality control. Committed to excellence in PCB assembly, Circuit Pak combines advanced defect-detection equipment with our numerous quality control measures to ensure your assembly meets or exceeds your expectations.
