Through-Hole Assembly Services

Through-hole components provide superior mechanical strength for applications subject to vibration, thermal stress, or high current. Ideal for connectors, transformers, electrolytic capacitors, and power semiconductors.

🌊

Wave Soldering

High-volume wave soldering for mixed SMT/THT boards. Nitrogen atmosphere for reduced oxidation. Preheat, flux application, and controlled wave contact for consistent solder joints.

🎯

Selective Soldering

Point-to-point selective soldering for complex assemblies. Precise flux and solder application to individual through-holes. Ideal for heat-sensitive components and dense boards.

🔧

Hand Soldering

Skilled operators for prototype and low-volume THT assembly. IPC-certified soldering technicians. Temperature-controlled stations with fume extraction.

🔌

Connector Assembly

Specialized assembly for high-density connectors: D-sub, USB, HDMI, RJ45, and custom headers. Press-fit and solder options available.
