THT Assembly
Through-hole assembly with craftsman-level quality
Wave and selective soldering backed by skilled manual insertion — THT assembly for power electronics, connectors, transformers, and every part that still belongs through the board.
Capability
THT and mixed-technology support
Wave Soldering
Lead-free wave lines for high-pin-count through-hole boards with controlled profiles and pallets for SMT protection.
Selective Soldering
Precise solder joints on dense mixed-technology boards — no risk to adjacent SMT components or flex sections.
Manual Assembly
Trained IPC-A-610 operators for odd-form parts, cable harnesses, press-fit connectors, and mechanical assembly.
Typical applications
Power supplies & convertersIndustrial controlsMotor drivesAudio equipmentConnector-dense backplanesHigh-voltage assembliesLED lighting
Quality focus
THT QA that goes beyond visual checks
- IPC-A-610 Class 2/3 workmanship standards applied and documented.
- Solder-fill verification — barrel fill inspected to class requirements, X-ray where hidden.
- First-article sign-off with photos before volume release.
- Hi-pot and functional test support for power and high-voltage assemblies.
- Conformal coating & potting available for harsh-environment products.
