The patented IsoThermal™ chamber technology is what differentiates Electrovert ovens from others.  In a reflow oven, the consistent thermal capability and control within the heated length is what matters most rather than the number of zones. The OmniES 7 uses a single IsoThermal chamber design producing a hybrid approach to consistent thermal capability and control that outperforms competitive low cost alternatives.  The OmniES produces ΔT’s less than ±3°C.  The OmniES is proven to require significantly less power than other ovens in the market.

The OmniMax and OmniES incorporate the patented IsoThermal™ Chamber Technology (ICT).  This is an advanced, efficient heating chamber design that provides maximum thermal performance.  Electrovert’s innovative approach to thermal transfer delivers highly efficient heat transfer throughout the entire process and product.  Consistent thermal performance of the ICT promotes excellent zone separation, minimizes cross board ΔT’s and allows for better control of time above liquidus.

The patented cooling module in OmniMax/ES series is designed to provide process flexibility, to meet the cooling slope requirements of thermally-challenging board assemblies, and to reduce the opportunity for flux dripping in the process area.  The air flow dynamics within the cooling zones are efficiently controlled for a balanced environment that can reduce nitrogen consumption up to 20-25%.  The design includes a patented dripless cooling module that significantly reduces the potential for flux dripping in the cooling area.  Excellent separation between the heating and cooling areas produces a tight control of time-above-liquidus. 

When it comes to maintenance, Electrovert believes that ‘less is better’.  OmniMax/ES series ovens include innovative designs that reduce maintenance requirements, extend time between maintenance intervals, and minimize the time required to perform maintenance. These innovations include:

• An industry-first dripless cooling module (patented technology).  Its innovative design extends the time between performing maintenance in the cooling area;
• ‘Intelligent Flux Control’ is a patented design that consists of a two-stage filtration system that incorporates self-cleaning features, simplicity in design, and provides the ability to perform full maintenance without stopping production;
• A chamber design that seals the cross and width adjust shafts out from the process area;
• Full and easy accessibility to all major assemblies.

The robust conveyor systems on the OmniMax/ES series convection reflow ovens are designed for years of worry-free use in demanding production environments.  The design includes features including:

• Cross shaft and width adjust assemblies that are sealed out of the process area;
• Robust conveyor rail extrusion and support assemblies that maintain rail parallelism;
• Linear guides and precision screw shafts that ensure a smooth motion and highly repeatable conveyor width;
• Precision Center Board Support (optional);
• Dual Track conveyor (with/without center board support) is optional for additional throughput capability.

At the end of the final assembly process, each OmniMax and OmniES system undergoes vigorous tests that are designed to ensure each system is lead-free validated and optimized.  Each system has multiple thermal profiles that are recorded utilizing a calibrated test vehicle.  The test vehicle simulates actual component temperatures and precisely verifies cross-board uniformity.  Cpk data is collected to verify machine performance and repeatability.  If the system is ordered with a nitrogen inerted chamber, dynamic testing is performed to ensure that the chamber inerts to a low ppm atmosphere (tests are conducted in a simulated production environment).  The Electrovert promise is that each OmniMax/ES system is lead-free validated and optimized.  In addition, the quality assurance data and reports are included in the machine documentation package that is provided with each oven.

The software and controls of the OmniMax/ES 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.
