JT Vacuum Reflow Oven
Production Description
SMT Reflow Oven | JT VAR-1000-N
- JT´s in-line type vacuum assisted reflow oven, vacuum module equipped, reduce the voids in a solder joint by 99%, and to meet high capacity production and direly use profile from non-vacuum reflow.
- 3-section conveyor: Heating zone, vacuum unit and cooling zone, adjustable individually.
- Independent temperature control zone, suitable for different temperature profile.
- Solve the problem of bubble & void, <1% void area can be achieved.
- High efficient vacuum pump unit equipped for fast down time.
- High production throughput, cycle time 40–60 sec, average.
- Equipped with high efficient flux collection system.
Vacuum Pressure Soldering Chamber
High efficiency, No cavity, low maintenance
Equipped unth vacuum unit to solve the problem of void, bubble, etc. Voids area can reach <1% by the vacuum pressure 10–5m bat.
Vacuum Level & Temp Profile
High accurate vacuum level and temperature profile
- Temperature of each zone can be adjusted individually.
- Pressure under 10 mbar still can meet TI ≤ 90S, TP ≤ 240°C.
- Infrared heating equipped in vacuum unit to meeting high through put settings.
Vacuum Soldering Comparison
Void area may reach about 25%
Under N2 & Vacuum unit applied void area can be reduced to 1–5% normally also 0.5% is possible.
