Surface Mount Technology (SMT) Assembly

SMT assembly is the cornerstone of modern electronics, enabling compact designs, higher component density, and improved electrical performance. Our SMT lines are equipped to handle a wide range of component types and package sizes, ensuring precision placement and reliable soldering.

Key SMT Capabilities:

• Fine Pitch Components: Expertise in placing and soldering fine-pitch components, including QFNs, BGAs, and micro-BGAs, critical for high-performance and miniaturized applications.
• High-Density Placement: Optimized processes for maximizing component density on PCBs, supporting complex circuit designs.
• Automated Optical Inspection (AOI): Utilized for rigorous quality control, detecting placement errors, solder defects, and missing components post-reflow.
• Reflow Soldering: Precisely controlled reflow profiles to ensure optimal solder joint integrity for various solder pastes and component types.
• Component Sourcing: Support for strategic component sourcing to mitigate supply chain risks and ensure material availability.

Through-Hole Technology (THT) Assembly

While SMT dominates new designs, Through-Hole Technology remains vital for components requiring greater mechanical strength, higher power dissipation, or specific form factors. Our THT assembly processes complement our SMT capabilities, providing a complete solution for mixed-technology boards.

Key THT Capabilities:

• Manual and Automated Insertion: Efficient handling of both standard and odd-form through-hole components.
• Wave Soldering: Controlled wave soldering processes for reliable and consistent solder joints on THT components.
• Selective Soldering: Precision selective soldering for boards with mixed SMT and THT components, minimizing thermal stress on sensitive SMT parts.
• Mechanical Strength: Ideal for connectors, power components, and other parts requiring enhanced mechanical stability.
