Odd-Form PIN Terminal Insertion by Southern Machinery: Dual-Head 12,000 CPH Throughput

The S-7020 Dual-Head PIN Eyelet Terminal Insertion Machine is Southern Machinery's answer to one of the most persistent bottlenecks in mixed-technology PCB Assembly: odd-form through-hole components that resist automation. PIN headers, eyelets, terminal blocks, and irregularly shaped connectors — these components have traditionally required manual insertion, driving up labor costs and introducing quality variability. The S-7020 changes that equation with 12,000 CPH dual-head insertion, IPC-9706 certified accuracy, and flexible feeding from bulk trays or tape-and-reel.
What Is This Machine Used For?
The S-7020 is a dedicated odd-form auto insertion machine within Southern Machinery's S-7000 series. It automates the placement and clinching of:
- PIN headers and eyelets — single-row, dual-row, and custom-pitch configurations
- PCB terminals — spade, ring, and fork terminals supplied on reel or in bulk
- Board-to-board connectors — power connectors, signal headers, and mixed-pitch interconnect
- Irregular through-hole components — any component that cannot be handled by standard radial or axial insertion heads
The dual-head architecture means two insertion heads operate in parallel, doubling throughput compared to single-head odd-form machines while sharing a common PCB transport and vision system.
Q: What makes the S-7020 different from a radial inserter?
A: Radial inserters handle components with two parallel leads in a fixed pitch, fed from tape. The S-7020 handles components with non-standard geometries — eyelets, terminals fed loose in bulk, connectors with multiple staggered pins — using custom gripping heads and flexible feeding systems. It fills the gap between standard radial/axial insertion and fully manual assembly.
Typical Application Scenarios
1. Automotive Electronics
PCB Assemblies inside ECUs, body control modules, and power distribution units frequently require heavy-gauge terminals and eyelets for wire-to-board connections. The S-7020 handles these at automotive-grade throughput with the repeatability required for IPC Class 2 and Class 3 acceptance.
2. Power Supply & Energy Systems
Switch-mode power supplies, inverters, and EV charging modules depend on PIN headers and high-current terminals soldered through the PCB. Manual insertion at these volumes creates a labor bottleneck — the S-7020's dual-head design directly addresses this by doubling insertion speed for high-mix power boards.
3. Industrial Control & Automation
PLC I/O modules, motor drives, and sensor interface boards often mix SMT components with through-hole connectors and terminals. The S-7020 integrates into a mixed SMT–THT line, handling the odd-form portion while Pick and Place machines and reflow ovens handle the surface-mount side.
4. Home Appliance & White Goods
Rice cookers, washing machines, and induction cookers — all use power PCBs with eyelets and terminals. The S-7020 has been demonstrated in automated rice cooker PCB Assembly lines, replacing manual insertion stations with consistent, high-speed automated insertion and clinching.
How It Integrates Into a Complete PCB Assembly Line
The S-7020 fits into a mixed-technology production line after SMT processes and before wave soldering:
- Solder Paste Printing (SPI) → SMT components placed by Pick and Place
- Reflow Oven → SMT side soldered
- S-7020 Odd-Form Insertion → PINs, eyelets, terminals, connectors inserted and clinched
- Wave Soldering → Through-hole components soldered in one pass
- AOI / Post-wave Inspection → Full board quality verification
Alternatively, for boards that are primarily through-hole, the S-7020 can operate upstream of a selective soldering system, inserting components onto bare PCBs before localized soldering.
Southern Machinery provides full-line integration: board handling (loaders, unloaders, conveyors), wave soldering machines, and AOI — all designed to connect seamlessly with the S-7020.
Key Selection Parameters
When evaluating an odd-form insertion machine, procurement and engineering teams should verify these parameters with the supplier:
| Parameter | What to Confirm |
|-----------|----------------|
| Insertion heads | Number of heads; compatibility with your specific component geometries (PIN, eyelet, terminal, connector) |
| Feeding options | Bulk bowl feeder, tray feeder, tape-and-reel feeder availability |
| PCB dimensions | Maximum and minimum board size; board thickness range |
| Placement accuracy | Tolerance in XY and angular axes; clinching quality |
| Changeover time | Time to switch between component types; programmability |
| Vision system | Fiducial recognition; component presence/absence detection |
| Throughput | Real CPH at your component mix and board complexity |
| Standards compliance | IPC, CE, and other certifications relevant to your market |
Note: Always request an on-site or video demo with your actual components and PCB samples. Published CPH figures assume ideal conditions — your real throughput depends on board layout, component mix, and feeder configuration.
ROI, Quality & Throughput Considerations
The S-7020 addresses three cost drivers simultaneously:
Labor Reduction. Manual PIN and terminal insertion typically requires 2–4 operators per shift for medium-volume production. One S-7020 replaces those stations with a single operator for loading and monitoring, reducing direct labor cost by approximately 45%.
Quality Improvement. Manual insertion introduces variability — missed PINs, misaligned eyelets, inconsistent clinching. Automated insertion with vision verification eliminates these defect categories, reducing rework and improving first-pass yield.
Throughput Consistency. A manual insertion station's output varies by operator skill, fatigue, and shift. The S-7020 delivers consistent CPH across shifts, enabling reliable production planning and line balancing.
When calculating ROI, factor in not just the machine cost but the reduction in rework labor, scrap PCB value, and line downtime from manual bottlenecks.
FAQ
Q: What component types can the S-7020 handle?
The S-7020 handles PIN headers, eyelets, PCB terminals (spade, ring, fork), board-to-board connectors, and other odd-form through-hole components. Custom gripping heads can be engineered for specific component geometries — consult Southern Machinery's application engineering team with your component samples.
Q: How fast is the S-7020 compared to manual insertion?
At 12,000 CPH with dual-head operation, one S-7020 can match the output of 3–4 manual insertion operators while delivering consistent clinching quality and eliminating missed-insertion defects.
Q: Does it integrate with existing SMT lines?
Yes. The S-7020 uses standard SMEMA-compatible conveyor interfaces, allowing seamless connection to upstream and downstream equipment — board loaders, conveyors, wave soldering machines, and AOI stations.
Q: What PCB sizes does it support?
The S-7020 accommodates PCBs up to 380 × 280 mm. For larger or smaller board requirements within the same component family, consult Southern Machinery about other S-7000 series models.
Q: Is training and support available globally?
Yes. Southern Machinery provides installation, operator training, programming support, spare parts, and remote diagnostics to customers worldwide. All documentation is available in English and simplified Chinese.
Q: What certification does the S-7020 hold?
The S-7020 is IPC-9706 certified for insertion machine performance qualification. Additional certifications (CE, etc.) apply depending on the destination market — confirm with Southern Machinery for your region.
