1. Introduction
Congratulations on your purchase of Batch Reflow Oven Model X-REFLOW305. X-
REFLOW305 is auniquely designed full convection Reflow Batch Oven for use in low
volume production such as simulation of a mass-production Reflow Oven, heat resistance
test of components and laboratory experiments where precise and accurate heating is
required. The unit has several unique features, which enhance operation. Full convection
heating with independent control of front and rear heaters, which enable hot air
temperature and time setting in 4 steps and free setting of various profiles for various
PCBs. A large inspection window allows monitoring during operation also applicable with a
microscope. The built-in computer uses closed-loop monitoring to ensure absolute
repeatability of the temperature profiles and has the memory to store 255 profiles allowing
very quick profile changes perfect for low volume assembly. The large backlight display
shows either the specific temperatures or time digitally or graphically. A Nitrogen Gas inlet
is standard.

3. Safety
lThe fumes emitted during soldering are irritants and therefore should be removed. A
pumped vent is located at the rear of the unit and should be ducted accordingly.
lArea close to the hood becomes hot, therefore care should be taken when working a
round this area.
lThis oven must be properly grounded.
lPlease read this operation manual carefully prior to use.
lArea around the viewing window becomes hot, therefore care should be taken when
working a round this area.
lAfter ending the cooling cycle, the inside of oven is still hot, therefore care should be
taken when removing and mounting the PCB.
lBe sure to wear the cotton gloves to prevent burns when taking out the PCB from the
oven and placing a new one. The PCB is still hot.
4. Unpacking and Set-Up
1Connecting to the Power Supply
X-REFLOW305 must be connected to 50/60Hz. 220-240V single-phase 16A power
supply.
2Operating Frequency
X-REFLOW305 has a changeover switch for 50Hz or 60Hz on the rear panel of the
unit, please set it to match your frequency. As the timing is dependent upon the
operating frequency, failure to set it on the correct value will result in timing errors
during the oven’s cycle. When the oven is first turned ON, the computer samples the
link and the set operating frequency displayed on LCD panel. Be sure to check that it
shows the correct frequency.
6
Circuit Breaker
There is a circuit breaker on the left-hand side of the rear panel, please turn it ON
prior to the operation.
3Power Switch
There is a power switch on the front panel, please turn ON after turning ON the circuit
breaker.
4Security Key Switch
A key switch is provided to prevent unauthorized access to the profile parameters and
the profile storage memory. The key must be in place and turned in the clockwise
direction “ON”before starting the oven or changing a profile. The key can only be
removed in the “OFF”position. Two keys are provided. One key is a spare, please
keep it in a safe place.
5Display Contrast
The display contrast is adjusted by turning the round knob next to the display.
6Nitrogen connection & Operation Procedure (Please refer to Illus. 1)
I. Attach the Nitrogen source(0.51/2) to the Nitrogen input port on the rear
panel of the oven.
II. Be sure that Nitrogen switch is set in the up position on the rear panel of the
oven.
III. Start the temperature profile running and the Nitrogen valve within the oven
can be heard to activate and Nitrogen is then released into the oven heating
area. The LED (GAS VALVE) on the front panel should light.
Note: The nitrogen valve will open at the beginning of the profile (Preheat 1). To allow
enough time to purge the oven, Preheat 1 should be set for 3 to 4 minutes.
7
IV. Once the temperature profile has completed its running cycle the Nitrogen
valve will turn off automatically and the front panel LED (GAS VALVE) will go
off.
Note: Nitrogen will not enter the heating area with the Nitrogen changeover switch
(Nitrogen/Air) in the down (Air) position.

6. Entering Temperature profile.
In the opening display press any key. The user prompt dialog box changes to:
PRESS ”+”KEY FOR STORED PROFILE
PRESS ”-” KEY FOR NEW PROFILE
Pressing the “+”key enters the procedure for loading a profile from the computer’memory
(Please refer to Page 10.Running a pre-installed profile).
Pressing the “-“ key allows new profile parameters to be entered using the numeric keys.

With the cursor flashing at the position “#”, pressing the ‘CANCEL’key at this point
returns to the previous user dialog box.
PRESS ”+”KEY FOR STORED PROFILE
PRESS ”-” KEY FOR NEW PROFILE
IF the “ENTER”key is pressed, the value currently displayed at the cursor position is
saved (The set value of the front heater is saved) and the cursor moves to the rear
heater setting.
Note: If the “CANCEL”Key is now pressed, the cursor moves to the front heater setting.
Entering the 3 digit temperature setting value, the display shows the rear heater
setting and the same value is displayed. If the same value is required for both the
front and rear, pressing the ‘ENTER’key will set the rear heater to the same set value
as the front heater. If the rear heater needs to be set at a different value from front
heater, enter the value using the numeric keys. When both heater values have been
entered the cursor is positioned at the ’TIME’zone value. Enter the desired time using
the numeric keys. (Unit of TIME is seconds) Pressing the enter key results in the
present displayed time value being saved. A numeric input will change the time value
set. Pressing the ‘CANCEL’key will move the cursor to the previous setting if an error
occurs.

This process is repeated for all 4 heating zones. The ‘CANCEL’key is used to go
back to a previous zone if an error is made and re-enter the correct value.
The time zone LED will flash at the bottom of the Panel and showing the zone you are
in while inputting the set values. The LED flashing moves in the following order.

The cursor is then positioned at the “cooling target”temperature (Cooling Cycle). This
value is the temperature that the oven must fall to before the profile is finished.
When the cooling target (cooling cycle) is entered, the user dialog box changes:

If the ‘CANCEL’key is pressed, the profile is not saved in the computer memory and
the oven will be ready to run. By pressing ‘START’key, the oven starts the heating.
If wanting to save the profile in the computer memory, a 3-digit number must be
inputted.
