Unit-i4 Questions and Answers

What preheating does the Unit-i4 include?

Standard bottom IR heater. Clearance: Top 95mm / Bottom 30mm. Provides efficient thermal conditioning essential for lead-free processing.

What PCB configurations does the Unit-i4 support?

1 nozzle active: W508×L508mm; 2 nozzles: L508×L250mm; 4 nozzles: W250×L250mm. This allows for optimization based on board size and throughput.

What differentiates the Unit-i4 from the Unit-i1?

2 pots with 4 individual pumps and 4 wave tunnels (vs 1 pot/1 pump/1 tunnel). It supports larger PCBs (up to 508 × 508mm) and higher power (22 kW).

What is the Unit-i4 adjustable nozzle distance range?

X direction: 250–280mm; Y direction: 140–255mm. This wide software-controlled range accommodates diverse layouts without mechanical reconfiguration.

What solder pot specifications does the Unit-i4 have?

2 pots (30 kg total capacity) with 4 individual pumps . Mechanical pumps are standard (electromagnetic optional) with a max temperature of 350°C.

What are the installation requirements for the Unit-i4?

Power: 3PH 220V 60Hz; Air: 3–5 bars; Exhaust: 800 m³/h; Footprint: 1,300mm (L) × 1,840mm (W); Weight: 700 kg; N2: 6–8 m³/h .

What real-time monitoring features are included on the Unit-i4?

Standard live-on camera, built-in automated wave height calibration, and a real-time solder process monitor via Windows 10 .

What is the Unit-i4 software programming time for new boards?

~10 minutes using SOLDER-IT point-and-click interface. No CAD import is required.

How does the Unit-i4 maximize ROI for a high-volume inline environment?

It delivers high throughput per square meter with dual-fluxer flexibility and automated calibration, reducing labor and rework costs.

How do the Unit-i4 four wave tunnels across two solder pots increase throughput?

They solder multiple locations simultaneously in parallel during a single pass, multiplying throughput without increasing machine footprint .
