S-70LD Odd-Form Insertion Machine by Southern Machinery
Manual odd-form component insertion remains the most persistent bottleneck in through-hole PCB assembly. Transformers, large electrolytic capacitors, connectors, relays, and switches require hand placement — slow, error-prone, and costly. The S-70LD Odd-Form Insertion Machine automates exactly this class of components, delivering robot-grade precision (±0.05 mm) to your THT line at a budget-friendly to mid-range price point.
What Is the S-70LD Used For?
The S-70LD is a standalone odd-form (special-shaped) insertion machine designed for non-standard through-hole components that radial and axial inserters cannot handle. It bridges the gap between 100% manual insertion and full-scale odd-form automation.
Typical components handled:
- Transformers and coils
- Large electrolytic capacitors
- Connectors (pin headers, terminal blocks)
- Relays and contactors
- Fuse holders and switches
- Power supply components
Typical applications:
- Automotive electronics (connector-heavy boards)
- Appliance PCBA (air conditioners, TVs, microwaves, induction cookers)
- Industrial power supplies and LED drivers
- Medical device PCB assemblies
- EMS factories with mixed-production THT lines

How the S-70LD Fits into Your PCB Assembly Line
- Preceding stage: Wave soldering machine (e.g., S-WS450) finishes bottom-side soldering
- Insertion stage: S-70LD places odd-form components onto the PCB after selective solder or manual pre-insertion
- Following stage: Inspection (AOI/SPI) or downstream conveyor to automation
- Integration: SMEMA-compatible — fits inline with existing board handling conveyors
The machine works as a stand-alone unit or inline within a fully automated THT line.
Key Selection Parameters for Buyers
- PCB dimensions — confirm maximum board size supported
- Component geometry — height, body size, lead pitch, lead count
- Feeding format — bulk/vibratory bowl, tube, or tray
- Target volume — 12,000 CPH handles medium-to-high volume
- Climate — standard factory environment (10–35°C)
ROI Perspective
The S-70LD replaces 3–5 manual insertion operators per shift at roughly 12,000 CPH sustained throughput. Consistent placement quality eliminates float-high, missing, and reversed-component defects. Southern Machinery provides ROI modeling case-by-case based on your board mix and labor rates.

FAQ
What components can the S-70LD insert?
It handles odd-form / special-shaped THT components: transformers, large capacitors, connectors, relays, coils, fuses, switches — any component that cannot be fed by radial or axial tape.
What is the maximum insertion speed?
The S-70LD achieves up to 12,000 components per hour (CPH) under optimal conditions. Real-world throughput depends on component mix, feeding setup, and PCB complexity.
Is the S-70LD SMEMA-compatible?
Yes. The machine uses the standard SMEMA communication protocol and can be integrated into an inline PCB assembly line.
What certifications does the machine hold?
CE certified, RoHS compliant, and SMEMA compatible. Quality assurance standards for global export.
What feeding options are available?
The S-70LD supports bulk feeding (vibratory bowl), tube feeding, and tray feeding. Configuration is customizable based on your component packaging.
How many workers can this machine replace?
Depending on board complexity and shift structure, a single S-70LD can replace 3–5 manual insertion operators, with ROI typically realized in months rather than years.
