What Is the S7020T Dual-Head Terminal Insertion Machine Used For?
The S7020T is Southern Machinery's high-throughput dual-head terminal insertion system designed to automate the placement of reel-taped terminals and radial components directly onto PCBs. By doubling the insertion heads to two independent pick-and-place units, the S7020T achieves insertion speeds of up to 12,000 CPH — effectively twice the throughput of a single-head terminal inserter in the same floor footprint.
This machine is purpose-built for EMS providers and OEMs in the power tool, automotive electronics, and consumer appliance sectors, where high-volume terminal insertion has traditionally been a manual bottleneck. Instead of hand-placing hundreds or thousands of terminals per board, operators load component reels and bulk trays once, and the S7020T handles the rest.
How it works: Each insertion head independently picks from a dedicated feeder — either a reel feeder for tape-packaged terminals or a bowl feeder for bulk components — and inserts them into pre-drilled PCB holes with vision-guided precision. The dual-head architecture means two components land simultaneously per cycle, cutting per-board cycle time by nearly half compared to sequential single-head systems.

Typical Application Scenarios
1. Power Tool Manufacturing
Cordless drills, circular saws, and angle grinders contain numerous quick-connect terminals and spade connectors across motor controller boards. The S7020T handles these at 12,000 CPH, enabling power tool OEMs to scale from pilot runs to full production without adding manual insertion stations.
2. Automotive Electronics
Automotive ECU, BMS, and body control modules require high-reliability terminal insertion for connectors that feed into wiring harnesses. The S7020T's dual-reel feeding and vision alignment system ensures consistent insertion depth and angle — critical for vibration-prone automotive environments.
3. Home Appliance Control Boards
Washing machine, air conditioner, and induction cooker controllers use a mix of terminals, eyelets, and PIN headers in varied orientations. The S7020T's dual-head flexibility allows simultaneous insertion of different terminal types from separate feeders, reducing changeover time between component variants on the same board.
4. Industrial Power Supply Assembly
High-current power supply PCBs for factory automation and energy systems rely on robust terminal connections. The S7020T's mechanical insertion force and depth control ensure gas-tight connections suitable for high-temperature, high-current operation.
How the S7020T Integrates Into a Complete PCB Assembly Line
The S7020T fits into the THT (Through-Hole Technology) section of a hybrid SMT-THT assembly line. A typical integration sequence looks like this:
- SMT Line — Solder paste printing (Stencil Printer) → Pick and Place → Reflow Oven → AOI inspection
- THT Section — Axial inserter (e.g., S4000) → Radial inserter (e.g., S-3010B) → S7020T Terminal Inserter → Odd-form inserter (e.g., S-70LD) → Wave Soldering (S-WS450)
- Post-Solder — PCB Cleaning (SCM5600D) → Final AOI → Depaneling (S380A) → Packaging
Southern Machinery supplies the entire line from a single source, which means coordinated conveyor heights, SMEMA-compatible interfaces, and one supplier for spares, training, and process engineering support. For factories adding THT automation to an existing SMT line, the S7020T can be integrated standalone with a PCB loader/unloader such as the SL660A or MLD350.
Key Selection Parameters
When evaluating a dual-head terminal insertion machine for your PCB assembly line, confirm these parameters with the supplier:
| Parameter | What to Ask | Southern Machinery S7020T Reference |
|-----------|-------------|--------------------------------------|
| Insertion speed | Rated CPH and whether it's per-head or combined | 12,000 CPH (dual-head combined) |
| Component types | Supported termination styles and packaging formats | Terminal, eyelet, PIN — reel tape and bulk bowl |
| PCB dimensions | Max/min board size the machine accepts | 380mm × 280mm (confirm exact range with Jason Wu) |
| Feeder count | Number of simultaneously active feeders | 2 reel feeders + 2 bowl feeders (independent per head) |
| Vision system | Alignment method, accuracy, and correction capability | Vision-guided insertion with positional compensation |
| Changeover time | Time to switch between component types / board programs | Modular feeder loading — confirm with demo |
| Floor footprint | Machine dimensions and service clearance required | 1700mm × 1300mm × 1600mm (confirm for your configuration) |
| Operating system & MES | Control software, data export, traceability | Windows-based with production data logging |
⚠️ Always request a current datasheet and sample insertion trial on your actual components before finalizing specification.
ROI, Quality & Throughput Considerations
A single-head terminal insertion machine running at ~6,000 CPH typically replaces 3–4 manual operators per shift. The S7020T's dual-head architecture at 12,000 CPH roughly doubles that output in the same footprint, allowing factories to:
- Eliminate 6–8 manual terminal insertion stations across two shifts
- Reduce per-terminal insertion cost by approximately 50–60% vs. manual labor (based on typical wage rates in major EMS manufacturing regions)
- Improve insertion accuracy — vision-guided placement virtually eliminates misaligned or skipped terminals, reducing rework and field failure rates
- Increase line utilization — simultaneous dual-feeder operation means one head can continue inserting while the other head's feeder is replenished, reducing downtime
For a mid-size EMS factory assembling 50,000 power tool controllers per month, the payback period on a dual-head terminal inserter typically ranges from 12 to 18 months through direct labor savings alone — not counting the additional gains from reduced scrap, rework, and quality-related warranty claims.
Frequently Asked Questions
Q: What's the difference between the S7020T and the standard S7020?
The S7020T is the dual-head variant. While the standard S7020 uses a single insertion head, the S7020T deploys two independent heads each with its own feeder, effectively doubling throughput to 12,000 CPH for high-volume production environments.
Q: Can the S7020T handle both reel-taped and bulk-packaged terminals?
Yes. Each head can independently draw from either a reel feeder (for tape-packaged terminals) or a bowl feeder (for bulk-packaged loose components), giving flexibility across your component supply chain.
Q: What PCB sizes can the S7020T accommodate?
The machine handles PCBs up to 380mm × 280mm. For larger or non-standard board sizes, contact Southern Machinery to discuss configuration options or explore the S-7000T model.
Q: How does the vision alignment system work?
Each insertion head captures a fiducial reference on the PCB before component placement. The system compensates for board registration errors and ensures consistent terminal insertion depth and angle — critical for connector reliability in high-vibration applications like automotive and power tools.
