Product Description
The AutoSolder 6 is a high-precision automatic soldering machine engineered for modern electronics manufacturing environments. Designed and assembled by hjLabs.in in India, it brings industrial-grade robotic soldering to small-and-medium scale PCB production lines.
Unlike manual soldering which depends on operator skill, AutoSolder 6 delivers consistent, repeatable solder joints at every cycle. The machine supports fully programmable solder volume, wire feed speed, and fan duration — letting you dial in the perfect parameters for each specific PCB layout and component type.
With a 400×300 mm working area, it accommodates most standard PCB form factors used in consumer electronics, industrial controls, and automotive electronics. The ±0.02 mm positioning accuracy ensures pads and through-holes are hit precisely every time, even on fine-pitch components.
Ideal for: PCB assembly lines, prototype shops, EMS/ODM manufacturers, R&D labs, and quality-conscious electronics businesses looking to eliminate cold joints and rework costs.

Manual vs Automatic Soldering
How does the AutoSolder 6 compare to manual hand soldering on a production line?
| Criteria | Manual Soldering | AutoSolder 6 |
|---|---|---|
| Speed | 5–10 joints/min (operator-dependent) | Up to 30 mm/s feed — 3–5× faster |
| Consistency | Variable — affected by fatigue and skill | Identical joints every cycle (±0.02 mm) |
| Labour Cost | High — dedicated skilled operator required | Low — one operator oversees multiple machines |
| Setup Time | Minimal — operator picks up iron | 30–60 min first-time programming; <5 min recall |
AutoSolder vs Hand Soldering vs Other Robotic Soldering
A detailed 8-criteria comparison so you can position the AutoSolder 6 against alternatives on your shop floor.
| Criteria | AutoSolder 6 | Hand Soldering | Generic Robotic Soldering |
|---|---|---|---|
| Throughput (joints/hr) | 800–1,200 | 300–600 | 1,000–1,800 |
| Repeatability (microns) | ±20 µm | ±200–500 µm | ±10–30 µm |
| Setup Time (per job) | 30–60 min first time, <5 min recall | None — but no consistency either | 2–4 hrs (CAD import + pathing) |
| Programming Complexity | Teach-pendant + simple GUI | N/A | Requires trained robotics tech |
| Footprint | 600 × 500 mm benchtop | Workbench + ESD chair | 1.2 × 1.0 m floor unit + cell |
| Operator Skill Required | Low — load & press start | High — IPC-A-610 certified solderer | Medium-High — robotics literacy |
| Maintenance Cost (annual) | ₹5,000–₹15,000 | Iron tips ₹8,000+; high attrition | ₹50,000–₹2,00,000 |
| Price (₹) | ₹25,000 | N/A (labour ₹2.5–5L/yr/operator) | ₹8,00,000–₹40,00,000 |
Generic robotic soldering figures benchmarked against entry-level Japti/Apollo/Unix systems available in the Indian market (FY2026 indicative). The AutoSolder 6 offers ~80% of the precision at ~3% of the cost — ideal for SMEs scaling from manual to automated soldering.
Use Cases We Solve
Real production scenarios where the AutoSolder 6 replaces inconsistent hand soldering with repeatable robotic joints.
PCB Assembly — Small-Batch Runs
Prototype shops and EMS lines running 50–500 PCBs per batch use the AutoSolder 6 to deliver consistent through-hole and selective solder joints without dedicating an IPC-certified hand-soldering operator.
Wire Harness Terminations
Tinning and joint-soldering of harness wire ends at programmed coordinates. Pairs with our AutoCut V2 wire cutter for a complete wire-to-board cell with predictable cycle time.
Sensor Module Assembly
Repeatable solder volume on small connectors and pin headers used in IoT sensor nodes, telemetry boards, and industrial control modules where joint quality directly impacts field reliability.
BMS & Battery Pack Soldering
Programmable dwell time and fan duration give controlled heat input on Battery Management System nickel-strip and balance-lead solder joints — minimizing thermal stress on adjacent cells.
