c. process chamber
heating section
.. heating is accomplished via forced impingement convection with side to side gas recirculation.
forced convection is provided by a proprietary blower system.
.. each zone utilizes btu抯 porcupine ii heating element. this element features a low mass, high
surface area open coil wire arrangement for fast response time and high reliability.
.. zones 1, 2, 7 and 8 employ 5-kilowatt heating elements top and bottom. zones 3, 4, 5 and 6
employ 2.7 kilowatt heating elements top and bottom. 5-kilowatt heating elements are available
for all zones as an option.
.. oven loading capability is 2 lbs/ft2 (10 kg/m2) based on a nominal conveyor speed of 32 in/min.
(81.3 cm/min.). with optional 5kw heaters in all zones the loading capacity increases to 3 lbs/ft2
(15 kg/m2)
.. the process chamber is a clamshell design and includes the capability to process large format
printed circuit boards up to 18 x 24 inches (457mm x 610mm). 24 x 24 inch (610mm x 610mm)
board capability is available as an option
.. cross belt temperature uniformity is within a 40 c delta t in the reflow zone. (using standard btu
uniformity test board)
.. zone to zone temperature isolation is greater than 600 c
.. access to the process chamber is accomplished via powered hood lift actuators.
cooling section
.. cooling is accomplished via fans with forced convection.
.. closed loop cooling control is available as an option.

rail height from floor 33.8 in. ?39.8 in. 859 mm ?1011 mm
.. programmable (recipe controlled) width adjust is included with the optional rail edge conveyor.
.. programmable multi-port lubricator is included with the optional rail edge conveyor.
.. belt deviation detection via programmable deviation alarm.
.. belt 揝topped?alarm is standard with over torque protection provided via slip clutch.
.. alarm and motion messaging via wincon?
e. oven controls
temperature control
.. temperature control is accomplished by sixteen (16) pid control loops of the oven control unit
(microprocessor) and windows?wincon?operating software. each zone is divided into
independent top and bottom control. temperature control accuracy is + / - .5?c no-load.
.. optional cooling control is accomplished by varying blower speed. cooling rate control is
selected via wincon?software allowing the user to select the cooling rate.
.. process over temperature protection is accomplished via wincon?software using
programmable alarm limits. power to the heaters is removed if the temperature exceeds the high
alarm limit.
.. redundant independent electronic over temperature protection is standard. in the event of an
over-temperature condition, power to the heaters is removed and audible/visual alarm activates.
the conveyor continues to operate in this condition.
operator interface
.. controls are located on the right hand side as viewed from the oven entrance.
.. the computer keyboard and flat panel display are located at the entrance front of the oven.
.. programming is accomplished via btu抯 wincon software. wincon operates on the
windows?xp platform.
.. thermal profiling can be accomplished using three dedicated thermocouple inputs located at the
oven entrance. btu is compatible with kic and ecd as an integrated software solution.
.. four (4) emergency power off buttons are provided, two (2) are located at the loading and two (2)
at the unloading sections.
.. a three color light tower to monitor the oven status is standard. indicators are red ?alarm
condition, yellow ?set-up or alert condition and green ?ready condition.
.. smart tracker provides an entrance and exit photocell, which senses product entering and exiting
the oven. this allows the system to count products for a given recipe, detect product drop/lost
and display a graphical view of the products. in the event of a product drop, an alarm will sound.
.. smart tracker also manages the oven smema ready/busy logic for up and downstream
communications to other equipment in the assembly line.
.. automatic shutdown sequencing is standard.
