TWS 1385-evo Reflow Oven

An innovative medium-size convection oven which has an outstanding quality-price ratio. The machine is 3 metres long (with a 2 metres tunnel) and produces excellent soldering profiles, together with high productivity. The evo range has a lower power consumption than its predecessors and is very easy to set up and operate with the new full colour touch screen controlling all the important aspect of the process.

The tunnel is divided into four heating zones, three for preheating and one for reflow. The air convection is directed horizontally by fans that blow the air from the centre of the zone to the surroundings. The window in the hood of the machine enables the user to observe the reflow process in real time, giving useful indications and allowing for thermal profile fine-tuning without using the recorder. The upper part of the soldering tunnel has an easy opening system that enables an immediate inspection and cleaning.

Air temperature is controlled by a microprocessor through K-type thermocouples placed in each zone, that keeps the temperature between tight limits.

Cooling zone is optimised to lower the temperature to the required level without causing unwanted thermal shocks either to soldering joints or to components.
To obtain the best soldering performance, the oven is equipped with a temperature recorder which can be connected to a PC to display the temperature profiles during the soldering process.

Thermal profiles can be obtained (to fulfil even the most complex demands) due to its four heating zones and the digital adjustment of the conveyor speed. Up to 14 programs can be stored and quickly downloaded. The heating elements are controlled by a PID regulator using Burst Firing commutation, complying to EMI standards.

Main parameters, which are constantly monitored by a microprocessor connected to the PC LCD display, shows:

  • Temperature set point, for each heating zone
  • Actual temperature, for each heating zone
  • Conveyor speed set point
  • Actual speed of the conveyor

TWS 1380 evo is equipped with a new built-in touch screen colour display with the new following functions:

  • “PID” algorithm to ensure a faster temperature adjustment in the four zones
  • Delayed connection of the zone in order to reduce power consumption during the zone heating
  • Possibility to graphically monitor the temperature ranges in all the zones

Once the operator has set the temperatures, the oven starts to heat up, and the colours showed on the screen represent the actual temperature deviation from the set point.

In the event of a power failure, a back up battery enables the conveyor to continue running until all boards have exited the machine.

The machine can also be configured with pin, edge and mesh conveyor:-

It can be equipped with a support bench sold as optional extra
