THT through-hole mounting – reliability and dependability in the tradition of electronics

In the rapidly changing world of electronics, dominated by miniaturization and surface mount technology (SMT), through-hole technology (THT) continues to play a key role. At Siltegro, we understand that reliability and dependability are the foundations of many electronic products, which is why we offer professional THT assembly services that complement our advanced SMT lines and comprehensive contract electronics assembly.

What is THT through-hole assembly?

THT through-hole assembly is a classic method of placing electronic components, such as resistors, capacitors, diodes and integrated circuits, by threading their leads through specially prepared holes in the printed circuit board (PCB) and then soldering them on the opposite side. Although it has been replaced by SMT surface mounting in many applications, THT remains irreplaceable in a number of critical applications.

Key advantages of THT mounting

  • Mechanical strength: THT components, thanks to being physically threaded through the board and soldered, are characterised by significantly greater mechanical resistance to vibrations, shocks and stresses. This is crucial in devices exposed to harsh environmental conditions.
  • High power and voltage: THT assembly is often preferred for high-power, high-voltage or heavy components that generate significant amounts of heat. Through-hole components dissipate heat better and are more resistant to thermal damage.
  • Ease of prototyping and servicing: Through-hole components are easier to assemble, disassemble and repair by hand, making THT ideal for prototyping, short production runs and devices that require frequent servicing.
  • Reliability in extreme conditions: In environments with variable temperatures, high humidity or exposure to contamination, robust THT connections provide greater stability and reliability.

THT assembly process at Siltegro

At Siltegro, we approach THT assembly with the same precision and attention to detail as SMT surface mounting. Our process includes:

  1. Component preparation: Careful selection and preparation of through-hole components.
  2. Manual or automatic placement: Precise placement of components in PCB holes, depending on the complexity of the design and the size of the series.
  3. Wave or manual soldering: We use wave soldering technology (for larger series) or precise manual soldering (for complex or low-volume projects), ensuring durable and reliable connections.
  4. Quality control: Each stage of the process is monitored. In addition, finished boards undergo visual quality control and functional testing to confirm compliance with IPC-A-610 standards and customer requirements.
