1. Introduction

Congratulations on your purchase of Batch Reflow Oven Model X-REFLOW305. X­REFLOW305 is a uniquely 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

l The 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.

l Area close to the hood becomes hot, therefore care should be taken when working a

round this area.

l This oven must be properly grounded.
l Please read this operation manual carefully prior to use.
l Area around the viewing window becomes hot, therefore care should be taken when

working a round this area.

l After ending the cooling cycle, the inside of oven is still hot, therefore care should be

taken when removing and mounting the PCB.

l Be 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

1 Connecting to the Power Supply

X-REFLOW305 must be connected to 50/60Hz. 220-240V single-phase 16A power
supply.

2 Operating 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.
