Designed for budget conscious assemblers with intermediate to heavy throughput requirements, Model 28D.400 wave solder machine comes standard with a number of advanced features. The wave solder system features an auto-cleaning titanium finger conveyor with motorized width adjustment that handles PCBs up to 15.75" (400 mm) wide. The internal, automatic spray fluxing system includes a precision, low-pressure atomizer. The highly stable, 4.2' (1300 mm) convection preheater activates fluxes while prepping the assembly for soldering temperatures. The 28D.400 wave solder machine also includes a high-capacity 370 kg (816 lbs. approximate weight for lead free solder), lead-free-ready titanium-alloy solder pot and color LCD touch-panel control, with all parts backed by a one-year warranty.
VERSATILITY FOR ANY WAVE SOLDERING APPLICATION
28D.400 is configured with dual waves to accommodate through-hole, surface mount and mixed-technology assemblies. The chip wave can be deactivated through the user interface for non-SMT applications, although the addition of the oscillating wave option will allow the chip wave to aid in hole fill and bridge reduction for difficult-to-solder boards of all technologies.
The standard maximum wave width of 410 mm (16") can be adjusted, relative to PCB dimensions, through the use of an optional wave reducer mechanism and helps to minimize dross formation. Board interval sensing for wave activation and an energy-saving standby mode also aid in dross reduction.
The solder module is driven by two heavy-duty, transducer-controlled 1/4 HP motors to ensure precise, uniform wave heights.
One titanium-alloy lead-free-ready solder pot with a 370 kg (816 lbs Approximate weight for lead free solder) capacity comes standard with the 28D.400. The solder pot is mounted to a heavy-duty, roll-out carriage assembly that allows for easy access and maintenance. For assemblers that have not entirely phased out lead-based solders, a second pot with a quick-connect socket can be added for easy conversion between lead-based and lead-free solders.
INTERNAL AUTOMATIC SPRAY FLUXER
The 28D.400 includes an automatic internal spray fluxing system in which a precision spray nozzle assembly is mounted to a reciprocating Y-axis drive mechanism to ensure even and accurate application of flux.
The system adjusts automatically to accommodate the PCB size and utilizes a high-precision, low-pressure atomizer to provide excellent coating and through-hole penetration.
TWO INDEPENDENTLY CONTROLLED CONVECTION PREHEATING ZONES
After flux application, boards enter a two-zone high-capacity forced hot air convection preheat with independent zone temperature controls to allow precise thermal profiling for proper flux activation and optimal solder wetting as assemblies enter the wave module.
If additional profiling control is needed, or for assemblies sensitive to top and bottom side temperature differential, a top-side preheater can be added at minimal cost.
EASY CONVEYOR ADJUSTMENT REDUCES SETUP TIME AND ENSURES PROCESS REPEATABILITY
Motorized conveyor width adjustment, from 50-400 mm (2"-15.75"), is standard on all 28D.400 wave soldering equipment, dramatically reducing setup time and eliminating operator inconsistency.
An aluminum-alloy pin-type conveyor input mechanism feeds the dual-titanium-finger conveyor, which includes a built-in finger cleaner, closed-loop speed control and overload protection.
Conveyor angle is adjustable from 4° - 7° and nominal speed setting is variable from 0.5-2.2 m/min (20"-87"/min) for maximized throughput.
