Conceptronic HVAHT102 (High Velocity Air) Series forced convection ovens are designed for SMT mass reflow soldering, Sn-PB as well as PB-Free alloys including epoxy, adhesive, and encapsulant curing. Tight uniformity and repeatable computerized control guarantees good solder joints today and many years to come.
The best of Conceptronic:
The Conceptronic HVAHT 102 ovens improved the great thermal performance that made Conceptronic original HVC ovens preferred by engineers for Automotive, Telecommunications, Medical, Military, and Semiconductor industries.
- 125% more heated length per zone.

- More standard features – Battery backup, Redundant thermocouple over temperature protection, Motorized conveyor adjust, Scheduled auto-start, SPC logging, Current limiting soft-start.
Discover the highest convection rates:
- Process PCB's with low setpoints and tighter process windows.
- Process a wide range of PCB types with minor
Discover 100% linear convection ratio:
Discover controlled convection flow:
- Direct more flow at the PCB per zone than any other oven for better profiles.
- Maximize velocity and angle transferring heat to the board to avoid component shift
- Control recirculation flow – "first in, first out" to minimize process contamination and flux condensing on warm heater cavity parts.
- Control flow from cooling into reflow, so process gas is cleanest where the solder joint is formed and flux does not condense in cooling.
Discover simple flux management:
- Minimize recirculation loops for cleaner process atmosphere, and lower maintenance heating tunnel.
- Filter out flux in powered exhaust ducts prior to factory ductwork.

Common Options (More Options Available):
- Light Tower - 3-color: green-amber-red signal tower (mounted above head level) constantly reports machine status.
- Board Counter / SMEMA Interface - Link to upstream and downstream machines communicates line readiness. Includes board count sensor.
- Blower Speed Control - 5 Independent Blower Speed Controls for Variable flow from 20-100%
- Under board Support - Bead Chain over rail system with x, y adjust, along the full length of the oven.
- Multiple Lane Conveyor - Choose 2, 3, 4, or even more rail systems with independent width control.
- Balance Weave Belt - For semiconductor processing.
- High Setpoint Temperatures - Available with maximum temperatures up to 450 °C.
- Custom Configurations - HVHT "Rigid Chassis" frame allows for easily customizable lengths for additional cooling or selective soldering modules.
- Low Part Count, Common Parts - Maintenance design philosophy with common blower throughout entire oven – 1 blower fits all. Common drive motor / and width adjust motor. Easy access to all areas of the oven.
- Exhaust is Filtered - Easy to change exhaust filters collect all flux prior to factory exhaust for reduced building maintenance.
- Self-diagnostics and backed up - Off-the-shelf computer communicates via Ethernet to industrial microprocessor based control with daily “restore” points created on all critical oven files. No calibration required for 20,000 hours.
- Energy Saving "soft-start" - Standard Adjustable “Sequential-zone” startup for reduced power consumption limits the maximum current draw during startup
- Current Smoothing - Smart Software: limits current spikes by applying the most power to the zones with the greatest deviation 60 times per second. Current draw is “smooth” resulting in lower electricity costs.
- Efficient Insulation - Efficient internal insulation in upper and lower heater cavity reduces power consumption, operating costs, and facilities air conditioning requirements.
