Combine surface mount and through-hole technologies on a single board. Optimal for complex electronics that require mechanical robustness and high component density.
Our mixed-technology assembly combines the precision of SMT placement with the mechanical strength of through-hole components, enabling complex hybrid board designs.
SMT placement first, then THT insertion and wave/selective soldering. Optimized process flow for maximum yield and minimum rework.
Full wave soldering bath for through-hole components with nitrogen enrichment for improved solderability and reduced defects.
Precise selective soldering for mixed boards where only specific THT joints need reflow without disturbing nearby SMT components.
SAC305 and other lead-free alloys for RoHS compliance. Proper thermal profiling for mixed SnPb/SMT + lead-free THT boards.
AOI after SMT, X-ray for BGAs, ICT after wave, and visual inspection at each critical process step.
Support for boards with heatsinks, press-fit connectors, large transformers, and heavy connectors that require THT mounting.
Stencil printing for SMT pads
Pick & place surface mount
SMT oven curing
Automated optical inspection
Through-hole component placement
THT solder connection
Mixed SMT + THT assembly is the right choice when your design demands both high-density electronics and mechanically robust connections.
PLCs, motor drives, power supplies with high-current connectors, relays, and transformers that require THT mechanical mounting.
ECUs, dashboard controllers, and safety systems that need robust connectors and through-hole components for vibration resistance.
LED drivers with SMD controllers and MOSFETs plus THT electrolytic capacitors and heavy power connectors.
SMPS, inverters, and battery management systems that combine SMD control circuits with THT power components.
