TWS 850
OV850
TWS 850 is a powerful and compact reflow and convection oven with one heating zone ideal to perform soldering operations for small to prototype size SMT manufacturing, to cure adhesive and pastes and to remove humidity from fine pitch parts prior to reflow using Hot Bake function.
The oven is capable of soldering boards up to 330 mm length and 240 mm width.

TWS 1150Evo
QV1150Evo
The TWS 1150 is a full forced air convection oven with 2 heating zones capable of soldering boards up to 400 mm in width.
With the oven operating at just 50 deg above the reflow temperature, this allows the boards to remain in the oven longer without causing thermal shock.
For this reason the process window is increased making profiling far easier and a wider variety of boards to be soldered with little adjustment to the profile.
The heating units are controlled by a PID system with “Burst firing” technique, for EMI suppression. “PID” algorithm ensures faster temperatures adjustment of the two zones.
In case of power cut, a pad-battery ensures the transport of the boards out of the heating tunnel.

TWS 1320Evo
QV1320Evo
The TWS 1320 convection oven is a full forced air convection oven complementing the whole range of our reflow systems. It is a four zones oven capable of soldering boards up to 400mm in width. A great variety of thermal profiles can be obtained (to fulfill even the most complex demands) due to their four heating zones and the digital adjustment of the conveyor speed.
In the event of a power failure, a back up battery enables the conveyor to continue running until all boards have exited the machine.
One upper window on the machine allows the user to observe the reflow process in real time.

TWS 1385Evo

TWS1385.
TWS 1385 EVO is the new model in the Evo oven series.

It can be purchased with the traditional mesh conveyor or with additional a chain conveyor kit in order to equip the oven with both conveyors.

The oven is 3 metres long (with a 2 metres tunnel) and produces a very good soldering profile, together with high productivity and low power consumption.

TWS 1385 EVO 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 a flip-opening system that enables an immediate inspection and cleaning.

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

A great variety of 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. Programs can be stored and quickly downloaded.
The heating elements are controlled by a PID regulator using Burst Firing commutation, complying to EMI standards.

The ovens’ main parameters, which are constantly monitored by a microprocessor connected to the touchscreen 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 1385 EVO is equipped with a new built-in LCD touchscreen 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.

It can be optionally equipped with a support bench
