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.

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.

There is a circuit breaker on the left-hand side of the rear panel, please turn it ON
prior to the operation.

3 Power Switch

There is a power switch on the front panel, please turn ON after turning ON the circuit
breaker.

4 Security 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.

5 Display Contrast

The display contrast is adjusted by turning the round knob next to the display.

6 Nitrogen connection & Operation Procedure (Please refer to Illus. 1)

I. Attach the Nitrogen source(0.5 1 /2) to the Nitrogen input port on the rear
