8-Head SMT Pick and Place Machine: Inside the S-800s Whole-Line Solution from Southern Machinery

Placement is where an SMT line puts most of its capital and takes most of its risk. A factory choosing a Pick and Place platform is not really buying head count — it is buying a rate it can hold, a component window it can actually feed, and an interface that lets the modules upstream and downstream of it work without an operator standing in between.

The S-800s Eight Heads Auto Pick & Place Machine from Southern Machinery is an eight-head, flying-vision placement platform aimed at medium and high volume SMT assembly. Southern Machinery publishes 32,000 CPH under optimum conditions (26,800 CPH to IPC-9850) with ±0.05 mm placement accuracy, driven by a magnetic levitation linear motor on the X and Y axes. It is supplied either as a standalone placement cell or as the centre of a published LED assembly whole-line solution.

Southern Machinery (Shenzhen, China, established 2011) designs and manufactures SMT and THT PCB assembly automation equipment and has served 237+ customers worldwide. Because the portfolio also covers printing, board handling, Reflow Oven, Wave Soldering, THT insertion and inspection equipment, a placement decision can be quoted as a complete line instead of a single machine.

What Is the S-800s Eight-Head Pick and Place Machine Used For?

Q: What does an eight-head Pick and Place machine actually do?

It picks surface mount components from taped reels and IC trays and places them onto a solder-paste-printed PCB at production speed. The S-800s carries eight placement heads. Each head has its own Z-direction step-servo motor for vertical motion and 0–360° rotation, and each of the eight pick-up heads carries a vision alignment camera. Vision On the Fly alignment runs inside the pick-and-place cycle rather than adding a separate inspection stop.

Q: Which components can it handle?

Southern Machinery publishes two component windows. Handled by the head camera: smallest 0402 (inch), largest 10 × 8 mm. Handled by the fixed bottom camera: smallest 1206 (inch), largest 30 × 30 mm. The published component list covers resistors, capacitors, IC, QFP and CFP. Substrates specified for the platform are PCB, FPC, MCPCB and PSB.

Q: How is it fed?

Standard configuration is 20 tape feeders (8 mm / 12 mm electric) across the front and back, expandable to 20 + 20 tape feeders as an option, with 2 IC trays at 325 × 135 mm. The feeder slots are motor-driven. Nozzle handling is automated: the Smart Nozzle System checks and replaces nozzles without a manual changeover stop.

Q: How does it align and verify placement?

Four mechanisms work together: Vision On the Fly alignment, a bottom vision system for large components and ICs, fiducial recognition with coordinate correction, and automatic vacuum detection. Gang pick and gang place are available for repeated component patterns. The placement platform itself is marble, specified for dimensional stability at high speed.

Q: What throughput can be expected in practice?

Published application figures are 30,000 CPH on LED bulbs — 3,000 bulbs per hour at 10 chips per bulb — and 35,000 CPH on LED tubes — 583 tubes per hour at 60 chips per tube. These are product-specific figures from the LED end of the range, not a guaranteed line rate: component mix, feeder count, board layout and print quality decide the real number on your floor.

Every figure above is as published by Southern Machinery for the S-800s. Configuration-dependent items — maximum board envelope, substrate thickness, conveyor height, nozzle set, power and air supply, footprint and machine weight — should be confirmed against your own product and facility before ordering.

Typical Application Scenarios

• LED bulb and LED tube assembly. The published throughput figures are built on exactly this work: 10-chip bulbs and 60-chip tubes, run in volume.
• LED lighting and display boards. High chip counts per board, tape-fed resistors and capacitors, and repeat patterns that suit gang pick and gang place.
• FPC and MCPCB products. Both substrates are specified for the platform, which matters for flexible LED strips and metal-core LED boards.
• EMS factories scaling up from semi-automatic or two-head placement. Eight heads and 20+ feeder positions move a line from prototype pace to production pace without a second machine.
• Appliance, power supply and general electronics boards. 0402-and-up chip content with QFP and CFP devices falls inside the published component window.
• Factories standardising on one equipment supplier. Printing, buffering, Reflow Oven, board handling, THT insertion and inspection are all in the same portfolio.
• Contract manufacturers building a second or third line to a repeatable template, instead of integrating mixed-brand modules each time.

How the S-800s Integrates into a Complete PCB Assembly Line

Southern Machinery publishes an LED assembly whole-line layout for this equipment family:

• Screen printer — 1,200 mm
• Placement stage — 2,000 mm
• Buffer conveyor — 1,500 mm
• Reflow Oven — 3,000 mm
• Buffer conveyor — 1,500 mm
• Published total line length — 9.2 m

(The brochure labels the printing and placement modules in this layout as semi-auto variants of the machine class; confirm the exact module mix you want quoted — the S-800s itself is a fully automatic, inline-conveyor platform.)

Why the handoff matters more than the peak rate

A placement machine only earns its published CPH when boards arrive printed, correctly oriented and at the right pitch, and when they leave without being stacked by hand. The S-800s carries a three-section conveyor with a SMEMA interface and automatic width control — the mechanical basis for that handoff. In practice:

1. The board leaves the printer and enters the placement stage on the first conveyor section.
2. Placement runs on the middle section while the head cameras and the bottom camera verify position.
3. The board exits on the third section and moves to a buffer conveyor, which absorbs the difference in cycle time between placement and Reflow Oven.
4. After reflow, a second buffer keeps the line flowing into inspection and board handling rather than letting boards queue at the oven exit.

Feeding and nozzle logistics around the platform

Twenty motor-driven feeder stations are the practical planning constraint. Before the machine is specified, count the unique tape feeders your product mix needs and compare that with the standard 20 positions versus the optional 20 + 20 arrangement, and decide whether IC trays at 325 × 135 mm cover your larger devices. Nozzle consumption should be planned the same way: nozzle type follows the component range, and the Smart Nozzle System's automatic checking and replacing reduces the manual intervention per changeover.

Services to plan alongside the machine

Southern Machinery's service scope includes spare parts supply, sub-assembly and retrofit kits, machine upgrading, training, and repair of SMT/AI machine parts such as lasers, motors, drivers and PCB boards. For an overseas line, installation and training support should be written into the purchase agreement before shipment.

Quality, Throughput and ROI

Three published attributes drive the quality case:

• ±0.05 mm placement accuracy on a magnetic levitation linear motor gantry — repeatability at speed, rather than accuracy that only holds at low rate.
• Bottom vision for large components and ICs up to 30 × 30 mm — the component class most likely to be misaligned and most expensive to rework.
• Automatic vacuum detection — a missing or partially picked component is flagged at the head instead of becoming an open solder joint found at AOI.

On throughput, the platform's economics come from head count and pattern handling: eight heads, 0–360° rotation per head, gang pick and gang place for repeated patterns, and Vision On the Fly so alignment does not consume cycle time.

Southern Machinery publishes its own ROI model for this line class, with the assumptions stated openly:

• Assembly earning used in the model: USD 0.001 per chip
• Line throughput used in the model: 30,000 chips per hour
• Monthly gross at 20 hours per day × 30 days: about USD 18,000 per month
• One-line equipment investment: about USD 70,000
• Monthly consumption and salary cost: about USD 10,000
• Published result: ROI under 9 months

Treat the model as a framework, not a quotation: substitute your own selling price per chip, your own shift pattern and your own labour cost, and confirm current equipment pricing with Southern Machinery. The point of the model is that on a 30,000-chip-per-hour line, the equipment cost is recovered inside the first year even at a fraction of a cent per placement.

Frequently Asked Questions

Is the S-800s a dedicated LED placement machine? No. The published throughput examples come from LED bulb and LED tube production, and the model sits in the Pick and Place machine for LED category, but the published component window also covers QFP and CFP devices up to 30 × 30 mm through the bottom camera, and the platform is specified for PCB, FPC, MCPCB and PSB substrates.

How many feeders does an eight-head machine need to stay productive? Match feeder count to head count. With eight heads picking in parallel, the feeders must be able to present components as fast as the heads consume them. The S-800s standard configuration is 20 tape feeders across front and back, with 20 + 20 available as an option — that optional arrangement is what most high-mix products end up needing.

What is the difference between the two published placement rates? 32,000 CPH is the rate under optimum conditions; 26,800 CPH is the IPC-9850 measurement, which uses a standardised test condition. When comparing machines from different suppliers, IPC-9850 is the number to compare like for like.

What component size range does it cover? From 0402 (inch) to 10 × 8 mm using the head camera, and 1206 (inch) to 30 × 30 mm using the fixed bottom camera. Very small devices and large ICs are therefore handled by different vision paths on the same machine.

Can it run inline with equipment from another supplier? The three-section conveyor carries a SMEMA interface and automatic width control, which is the industry-standard handshake for inline SMT equipment. Exact conveyor height and board-transfer details should still be confirmed with Southern Machinery against your existing line.

What should a buyer confirm before ordering? Maximum board and substrate envelope, substrate thickness, conveyor height and transfer direction, nozzle set for your component mix, tape feeder quantity (standard versus optional 20 + 20), IC tray requirements, power and air supply, footprint and machine weight, programming and offline software, and the spare-parts and training package.

Next Steps: Get a Configuration Match for Your Line

Whether the S-800s is right for your product depends on three numbers you already have: the number of unique components per board, the target units per hour, and the board envelope. Send those to Southern Machinery and the placement stage, feeder configuration and line layout can be matched to them.
