As the complexity of board assemblies continues to increase, board manufactures are looking for the best solution in a wave soldering system.  The solution must meet their soldering expectations for today as well as for the future.  The Electra is the machine of choice by major OEMs, EMS providers, and high reliability manufacturers.

Achieving the best solder joint quality, maximum topside hole fill, and zero defects are challenges with high mass, difficult-to-solder PCBs.  The Electra’s features, including ServoJet™ fluxing, forced convection preheat, and UltraFill 4.0, DwellMax 4.0, and DwellFlex 4.0 solder nozzles, provide board assemblers the capability to process the most difficult soldering applications in the most demanding environments.

The Electra has been soldering lead-free applications for many years.  The cast iron solder pot and its components are resistant to the corrosive nature of lead-free solders, and are capable of withstanding temperatures of 302° C (576° F).  All components that come into contact with the solder are titanium as standard.  Features such as our Quick Change solder pot provide the flexibility to easily change alloys in a safe and timely manner.

Proven performance and reliability are hallmarks of Electra.  Electrovert holds the industry reputation as having the most reliable wave soldering systems that last the longest when compared to other makes.  Board assemblers know the value in owning an Electrovert wave soldering system.  The Electra carries a lifetime warranty on the solder pot casting to the original owner (see the full explanation in terms and conditions). 

High-end and high reliability board assemblers recognize the importance of having the ability to process large, thick assemblies and pallets through their wave solder system.  The Electra is one of the only wave solder systems in the industry to have 610 mm (24” inch) process width capability.  The robust conveyor is designed to handle the weight of thick boards and pallets while automatic lead clearance and motorized width adjustment are standard.

Electrovert’s UltraFill™ 4.0, DwellMax™ 4.0 and DwellFlex 4.0 solder nozzles are designed to provide maximum top-side hole fill, provide the best hole fill quality, improve first pass yields, reduce dross, and promote easy maintenance. DwellMax 4.0 extra-wide chip nozzle and modified UltraFill 4.0 nozzle are ideal for soldering thick, high thermal mass circuit boards.

The Electra is capable of up to 2.4 meters (8 feet) of bottom side preheat and up to 1.8 meters (6 feet) of topside preheat. Multiple forms of preheat are offered for complete process flexibility; these include IsoThermal™ forced convection, fast response IR, and Infrared radiant. All preheat modules are ‘plug and play’, allowing preheat configurations to be located in any position, location, and 100% interchangeable.

As the complexity of board assemblies continues to increase, fluxing quality has become more of a focus to ensure soldering quality.  Electrovert offers the best fluxing technologies available in the marketplace.  The ServoJet fluxing system provides the ultimate in precision deposition and hole penetration (OA version available for aggressive flux applications) while ServoSonic™ and ServoSpray™ fluxing systems are available for ultrasonic and value-based solutions.

The software and controls of the Electra were designed to be user-friendly. The Windows® operating system is multi-functional and easy to use.  The 3D GUI provides the user a real-time view of the complete machine modules, operation, and product being soldered.  All Electrovert systems have a customizable ‘dashboard’ quick view screen.  Quick view allows engineers and operators to view critical machine parameters that are important to the process or application.

Automation, defect reduction, repeatability, MES information management and simplified operation continue to be market drivers across all aspects of board assembly manufacturing. Electrovert’s Auto Exit Wing feature provides the level of automation that allows an automated adjustment of the laminar wave flow to match the board velocity for reduced defects. The recipe-controlled set-point ensures the wave dynamics are automatically adjusted ensuring wave flow dynamics are optimized for each PCB type and application.

DwellFlex 4.0 - Brochure

The patented UltraFill 4.0 solder nozzle is an ideal solution for lead-free soldering. The UltraFill 4.0 nozzle is 40% wider than traditional tin-lead nozzle to increase contact time. The nozzle placement reduces the temperature drop between nozzles and improves hole fill. UltraFill allows either air or nitrogen operation through the same design without switching nozzles. Nitrogen or air operation can be selected through the desired recipe, without the need to change nozzles (also available with the rotary chip nozzle).

DwellMax 4.0 is a patented process solution that meets the challenges of lead-free wave soldering. The extra-wide chip nozzle and modified UltraFill 4.0 nozzle are ideal for soldering thick, high thermal mass circuit boards, increasing throughput capability. With conventional wave soldering technology, thick multi-layer and/or high thermal mass circuit boards are often accompanied by high cost from low yields, slow production speeds, rework costs, and the collateral damage associated with a rework loop. The innovative design of DwellMax 4.0 alleviates these problems and provides better PTH fill at significantly faster conveyor speeds. The benefits of the nitrogen tunnel include improved solder wetting and reduction in dross by up to 83%.

DwellMax 4.0 benefits include:

ExactaWave is a patented, high-reliability sensor with closed-loop feedback designed to control the solder wave height relative to the board. Its ability withstand temperatures up to 300° (573°F) makes it perfectly suited for precision soldering applications.

The ExactaWave system compensates for changes in solder level, dross accumulation and set-up changes made during maintenance. Thus, a set-point entered in a recipe always produces the same result. The ExactaWave’s seamless integration into the soldering machine’s software also allows it to operate in standby mode and is a parameter that can be data logged with trending capability.

The ServoJet system ensures thorough flux penetration by utilizing concentric air atomization.  It offers a programmable method of applying flux that results in consistent flux deposition and reduced flux usage.  The ServoJet utilizes air atomized multiple jet technology that is 100% integrated into the wave soldering system software.  [servojet]
