S7020 PIN, Eyelet, and Terminal Insertion Machine: 12,000 CPH THT Automation from Southern Machinery

The S7020 Series PIN, Eyelet, and Terminal Insertion Machine from Southern Machinery (Shenzhen, China) is a dual-head through-hole (THT) auto-insertion system rated at 12,000 CPH. It places PINs, eyelets, terminals, and selected odd-form parts with 360° insertion angles, visual correction, and inward or outward clinching — built to eliminate the most repetitive manual insertion work on EMS, ODM, and power-electronics lines.

What Is the S7020 Insertion Machine Used For?

The S7020 is used to automate through-hole insertion of PIN, eyelet, and terminal components that are still done by hand in many factories: relay and connector pins, PCB standoffs, eyelets, terminals from reel or bulk packaging, and other hardware-style parts that a pick-and-place machine cannot feed.

Southern Machinery's product videos show the S7020 platform configured for power board assembly (MOS transistors and connectors) and appliance control boards such as rice cooker PCBs, with clinching to lock leads after insertion. In short: if a component is rigid, through-hole, and repetitive, the S7020 is a strong candidate to take it off the manual bench.

• Power: single-phase 220 V AC, 50/60 Hz, 2 kVA

Typical Applications for the S7020

The S7020 fits production environments where through-hole hardware is a bottleneck rather than a sideline:

• Power supply and LED driver lines — terminal blocks, pin headers, and eyelets on ballast and driver PCBs
• Appliance control boards — connectors and MOS-type components on rice cooker, induction cooker, and air-conditioner control PCBs
• Automotive electronics — connectors and terminals where mechanical retention matters in vibration environments
• Industrial control and instrumentation — terminal insertion on I/O and relay boards
• EMS/ODM high-mix lines — one machine that can be re-programmed between PIN, eyelet, terminal, and selected odd-form jobs

Because the S7020 reads positions from visual programming and EXCEL data, job changeover is a programming task rather than a mechanical re-tooling project — an important point for factories running multiple board types per shift.

How the S7020 Connects to a Complete PCB Assembly Line

In a typical mixed SMT + THT factory, the S7020 sits in the THT segment of the line:

1. SMT segment — screen printer, pick-and-place, reflow oven, SPI/AOI
2. THT segment — auto insertion (radial and axial machines, plus the S7020 for PIN/eyelet/terminal and odd-form parts), then wave soldering
3. Post-solder — inline lead cutting, PCBA cleaning, final AOI, and functional test
4. Board handling — loaders, conveyors, turnover/flip modules, and unloaders keep the line flowing between segments

Southern Machinery supplies all of these segments, so the S7020 can be delivered as part of an integrated line rather than a standalone island — including the loader-and-conveyor configurations shown in their inline 40-station insertion line photos.

S7020 Selection Checklist: What to Confirm Before Buying

The S7020 is configurable, so buyers should confirm these points with the supplier rather than assume a fixed default:

• Component list and packaging — are your terminals supplied in bulk or reel? Both feeding systems exist, but the right one must be matched to your component.
• Lead and hole dimensions — verify your board's insertion-hole tolerance against the 0.5 ± 0.1 mm lead-clearance guideline.
• PCB size and panelization — standard capacity is 380 mm × 280 mm; confirm larger formats during quotation.
• Clinch style — inward vs. outward clinch should match your mechanical retention and rework strategy.
• Changeover workflow — confirm the visual programming and EXCEL import workflow with your engineering team's data formats.
• Line integration — confirm conveyor height, board handling modules, and communication with your existing line and MES requirements.

ROI, Quality, and Throughput

The business case for the S7020 rests on three measurable effects:

• Throughput — 12,000 CPH removes the manual-insertion bottleneck at the front of the THT line; Southern Machinery's product page positions the machine to reduce labor cost and raise productivity.
• Quality — 360° angle control, ≤ 0.8° vertical error, visual correction, and consistent clinching reduce polarity mistakes, bent leads, and pull-out defects that drive rework after wave soldering.
• Waste — automated feeding and placement minimize material waste and scrap compared with hand placement of expensive terminals and connectors.

For factories currently hand-inserting terminals or PINs across multiple shifts, the payback is usually calculated on headcount reduction alone, before counting the quality yield improvement.

FAQ

What is the S7020 insertion machine used for?

It automates through-hole insertion of PIN, eyelet, and terminal components, and can be configured for selected odd-form parts such as MOS transistors and connectors, as shown in Southern Machinery's production demos.

What speed can the S7020 reach?

The documented 2-head configuration runs at 12,000 CPH. Multi-head variants appear in product videos; confirm the configuration best suited to your component mix with the supplier.

Which PCBs can the S7020 handle?

Standard PCB capacity is 380 mm × 280 mm, with enlarged sizes available on request. The board design rule is an insertion hole 0.5 ± 0.1 mm larger than the component lead.

Does the S7020 support clinching?

Yes. The machine offers both inward and outward clinching to lock leads after insertion, improving mechanical retention and reducing post-solder defects.

What feeding systems are available?

The S7020 supports vibration bowl feeders for bulk-packaged terminals and reel feeders for taped components.
