INSPIRED INNOVATION
u PBC Burn-In Oven
Designed for multiple burn-in applications
Despatch burn-in ovens are engineered specically for applications such as high
dissipation forward bias, high-temperature reverse bias, dynamic and static
burn-in of IC, RAM, ROM, microprocessors and other semiconductor devices.
FEATURES AT A GLANCE
u
High volume recirculating fans maintain consistent, uniform
temperatures required by MIL STD 883D while removing heat
generated by the load.
u
Rear wall is easily disassembled and removed to simplify
fixturing of power leads or feed-through boards into oven.
u
Traditional horizontal loading. Side to side horizontal airflow
provides uniform atmosphere flow across horizontally
positioned loads.
u
Over-temperature protection control monitors maximum
temperature and shuts off heater if setpoint is exceeded.
u
Easy-to-use temperature controller featuring user-friendly arrow
buttons for changing setpoints. The controller also contains
programmable EZ-Keys enabling simple one-touch operation of
repetitive user activities.
MODEL OPTIONS
u
Three sizes: 8, 18 or 32 cu ft
(226.5, 510 or 906 liter)
u
Maximum temperature of 260˚C (500˚F)
u
High Dissipation Capacity
u
Controller communication includes EIA 232/485 Modbus® RTU
and supports network connectivity to a PC or PLC.

OPTIONS
u
Power supply cabinet is a standard E.I.A. 19” (48 cm) cabinet and
aesthetically matches the oven. 78” (198 cm) usable opening height.
u
Increased dissipation allows increase in live load capacity without risking
over temperature.
u
Circular chart recorder provides seven-day permanent record of process
temperatures.
u
Automatic damper controls amount of incoming fresh air while saving energy.
u
Rapid cool-down provides faster cycle times.
u
Back up/Redundant Hi-Limit to provide temperature protection in the event
the primary device fails.
u
Door switch to de-energize the heater and fan when the chamber access
door is opened.
u
Access port at rear of oven for test connections.
u
Casters on bottom of unit for mobility.

Notes:
1 Assumes ambient of 25ºC. Minimum temperature will be slightly higher with increased recirculating fan option.
2 Dissipation is reduced by 17% on 50 Hz. (Option available for full rated dissipation).
3 Live load evenly distributed provides maximum of 6°C mean temperature gradient.
