Vacuum Oven
Indeecon vacuum ovens deliver precision drying and degassing from lab to semiconductor grade. J-STD-033 compliant, electropolished SS-316L. Request a quote.
A vacuum oven removes atmospheric moisture and dissolved gases from components under controlled temperature and pressure. Critical in semiconductor packaging, PCB assembly, and battery manufacturing where even trace moisture causes failure. Unlike conventional ovens, vacuum environments enable ultra-low pressure baking (as low as 0.1 mbar) without thermal degradation—ideal for MSL (Moisture Sensitivity Level) 5–6 components and wafer-level packaging.
Key Specifications
- Operating vacuum range up to 10^-2 mbar (or better)
- Uniform radiant heating for delicate samples
- Stainless steel internal chamber with polished finish
- Integrated vacuum pump with oil mist filter option
- Programmable digital controller for temp and vacuum
Key Features
- Individual Shelf Heating (Optional): Direct-conduction shelves ensure uniform wafer/PCB temperature via metallic contact rather than radiant heat.
- Precision Vacuum Control: Digital solenoid valves + Pirani/Capacitance Manometer gauges maintain steady-state vacuum ±5% over 8-hour bake cycles.
- Inert Gas Purge & Backfill: Integrated N₂/Ar ports enable oxygen-free cooling and chamber normalization after vacuum cycles.
- Observation & Safety: Dual-pane tempered glass + polycarbonate shield for unobstructed part visibility (Class 100 cleanroom compatible).
- Electropolished Internal Surfaces (Semiconductor Series): SS-316L electropolish reduces outgassing and contamination for sub-micrometer feature processes.
- Modular Shelf Design: Tool-free removal for thorough cleaning and reconfiguration between product lots.
- ⚡ J-STD-033 Compliance: Our semiconductor vacuum ovens meet the IPC-J-STD-033 standard for moisture-sensitive device handling, bake-out profiles, and dry-pack validation.
- ⚡ Electropolished Chambers: Semiconductor series features electropolished SS-316L internal surfaces with <0.01 mbar/h leak rates, critical for sub-0.1 μm feature protection.
- ⚡ Direct-Shelf Conduction Heating: Optional direct-heating shelves replace radiative heat, enabling ±2°C temperature uniformity across wafer stacks and reducing thermal cycle time by 30%.

Frequently Asked Questions
Q: What is the difference between radiative and direct-contact shelf heating?
A: Radiative heating relies on infrared emission from chamber walls, while direct-contact heating uses electric resistance heaters embedded in shelves. Direct contact is 2–3°C more uniform and 30% faster but is premium-cost; use for wafer/BGA lots.
Q: How often should I recalibrate the vacuum gauge?
A: Annual NABL calibration is recommended for ISO 9001 traceability. Our in-house lab offers turnaround in 5 business days.
Q: Can I use silicone seals instead of Viton in semiconductor applications?
A: No—silicone outgasses above 150°C and compromises ultra-low-vacuum (ULV) performance. Always use Viton (EPDM) for 0.1 mbar and below.
Q: Do you offer retrofit kits for older vacuum ovens?
A: Yes. We can upgrade vacuum gauges, heating controls, and shelf assemblies in legacy systems. Contact our retrofit team for a site survey.
