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 1,2,9 and 10 employ 5kw heating elements top and bottom. zones 3-8 employ 2.7kw
heating elements top and bottom. 5kw 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 38 in/min.
(96.5 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) (wxl)
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 60癈.
access to the process chamber is accomplished via powered hood lift actuators.

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.
over torque protection provided via slip clutch.
alarm and motion messaging via wincon..
e. oven controls
temperature control
temperature control is accomplished by twenty (20) 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 the six dedicated thermocouple inputs located at the
entrance of the oven. btu includes winkic. by kic thermal profiling 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.
automatic shutdown se is standard.

(note: consult final installation drawing for precise specifications. this is to be used a guide)
electrical values are estimated. actual startup power may vary depending on oven configuration.
operating power is typical and dependent on product loading. soft start power limiting is possible
via wincon. software and should be specified at time of order.
all utility values must be finalized at time of order. a detailed installation drawing is provided once
final configuration is established.
