lf-ach front view

The X-Reflow306 LF-ACH was developed in response to a customer's request. They needed to perform heat treatment of an aluminum part with a height of 3.2 inches. A taller heating chamber was built to accommodate the part.

Due to the significant increase in the heating chamber's volume, as well as the weight of the heated object exceeding the design limits for previous ovens, the time from a cold start to 220 deg. C. increased. A graph of the temperature rise is shown below. The heated object inside was an aluminum structure with a 1500 diameter and 3.2 inches height.

Technical specifications:

Model

X-Reflow306 LF-ACH

Reflow area

12"x12"x3.5" (305x305x90 mm)

Temperature range

50°C to 360°C

Number of Zones

Purging, to push oxygen out + variable, three to five zones, set by the operator for each program. Last zone is a cooling zone. So, the oven can have 3 zones or 5 zones.

Heaters

2 Heaters (Front and Rear) 3.45kW (230V) and 3.45KW (208V) - 

Max. PCB size

12"x12" (305x305 mm)

Supply Requirements

30 amps, 230V 50/60 Hz (Max power consumption: 6.9 kW)

Cooling Cycle

Last (Fifth) Zone

Monitoring Window Size

7.8"x7.8" (200×200 mm)

Nitrogen Connection

Standard Connector. Nitrogen pressure:1/2-1bar (7-14.5 psi)

Size

L=28"xW=21"xH=15.4"
(L=711mm x W=530mm x H=390mm)

Weight (unpacked)

145 lbs. (~68 kg)

Computer profile control

Allows pre-programming, storage and recall of up to 255 programs

Communication with PC

RS485 port (XKAR X485-USB converter required to connect to PC USB port)

Advanced Features

  • Display of the actual temperature/time numerically or as a graph and full indication of set functions and process parameters along with their values in the Process Window.
  • Independent off set for the 2 heaters, (useful when processing unevenly loaded boards).
  • RS-485 port for downloading firmware upgrades from a PC and monitoring air and two additional “K” Thermocouples during reflow process. (X-KAR R485-USB Converter is needed for connection to a PC and X306 Oven Monitor Software for monitoring and displaying on a PC real temperature during the heating cycle. X-KAR XTC-Profiler (Eight TC inputs) is also recommended for multi-point monitoring.
  • Ready to solder in Nitrogen environment and to connect Residual O2 Monitor.
  • Means to monitor the process in progress (besides the on-board LCD display)
  • Power at Max Mode, which allows for pre-setting a pre-reflow temperature of the heated object and a maximum temperature of this object by means of control of the heating by the “K” thermocouple attached to the heated object and the TC-B socket at the back of the unit.
