Why Through-Hole Technology Still Matters

THP Assembly

Through-hole soldering provides robust mechanical strength by anchoring components through the board and soldering on both sides, creating joints that can withstand mechanical load far beyond what SMT connections can typically manage.

This method is particularly valuable for assemblies that operate in demanding environments or incorporate legacy or high-power components. While it may require more manual labour and precision, the resulting circuit boards deliver unmatched durability and service life, especially in safety-critical or mission-dependent systems.

Our process combines manual craftsmanship and automated insertion equipment, ensuring both scalability and precision. Every project benefits from rigorous inspection, testing, and process control to meet or exceed IPC standards.

Industries That Depend on Through-Hole PCB Assembly

Even as electronics become smaller and faster, many industries continue to depend on through-hole PCB technology to overcome environmental and operational challenges. In sectors such as aerospace, defence, automotive, industrial control, and medical equipment, the cost of failure is high and reliability can’t be compromised. Systems exposed to wide temperature ranges or high current loads need assemblies with mechanical integrity that surface-mount solder joints alone can’t provide.

Manufacturers of power supplies, communication infrastructure and diagnostic instrumentation face similar pain points: connectors that loosen over time, heavy components that fatigue joints, or boards that must survive years of use in the field. Through-hole assembly mitigates these risks by ensuring strong mechanical bonds, serviceable joints, and long-term stability. For many customers, a hybrid SMT and through-hole solution offers the best balance of electrical performance, compact design, and durability. Cleveland Circuits is equipped to deliver exactly that.
