Heller Industries 1911MK5-VR Nitrogen Vacuum reflow oven comprises 11 zones, a vacuum chamber, closed-loop nitrogen atmosphere control and Heller’s award-winning COOL-PIPE flux management system.
Of the oven’s 11 zones, ten deliver convection heating with one infra-red (IR) zone located strategically inside the oven’s vacuum chamber. This delivers proven advantages in void-less solder paste reflow processing, leading to long-term solder joint reliability.
The 1911MK5-VR delivers on ambitious performance metrics to help manufacturers streamline SMT assembly. It targets voiding ratios of less than 2% and cycle times of 40 seconds for single-lane implementation and 20 seconds for dual-lane systems. It maintains Heller’s solder paste reflow specification, including liquidous times of under 60 seconds. In addition, the oven is suitable for high temperature applications up to 450°C.
Flux Free within the vacuum chamber. In-zone IR Heating prevents flux residues precipitating within the vacuum chamber routine lubrication PM every 4 months.
Advantages and unique features
- 10 convection heating zones (top & bottom)
- Replicate standard thermal profiles
- 1 IR heating zone (Top)
- Single lane EHC
- Active heating through the vacuum phase
- Nitrogen atmosphere
- 3 cooling zones
- Cycle times of 40 seconds
- < 1% Void Rate – Heller vacuum reflow ovens provide best-in-class performance for removing voids in solder joints and interfaces.
- No Solder or Flux Splatter – Heller vacuum pumps offer closed-loop control for a controlled multi-step pump down and re-fill. This prevents yield-killing solder and flux splatter that can occur with single stage, open-loop vacuum systems.
- Heated Vacuum Chamber – Heaters allow for peak temperature to be reached inside the vacuum chamber for more process flexibility. High chamber temperatures ensure for no flux buildup inside the chamber.
- Low Maintenance for Low Operating Costs – Advanced flux management systems allow for less periodic maintenance and fewer required consumables.
- No Shifting Parts – Heller’s smooth-travel conveyor system ensures that components are not shifted or moved during travel throughout the oven. Boards on conveyor experience minimal vibration during travel – including entering and exiting the vacuum chamber.
- Highest UPH – Heller vacuum reflow offers an optional dual rail conveyor, for the fastest throughput.
- Leadership and Experience – With over 5 years’ experience in vacuum reflow, Heller Industries is recognized as a leading supplier of vacuum reflow technology.
