Our Reflow Ovens

Once the boards have been populated by our Surface Mount Machine they are ready to be put through the reflow oven. We have two reflows that each benefit the production line.

A reflow oven is a machine used primarily for reflow soldering of surface mount electronic components to printed circuit boards (PCB).
A Squared Technologies currently has two reflow ovens, the Mistral 260 and the NeoDen6.

MISTRAL 260

The Mistral 260 uses re-circulated hot air to accomplish reflow on the surface mount populated PCBs that travel through the oven.

An assortment of board sizes are able to be re-flowed with the same heat profile because the Mistral 260 produces a constant, even heat. This means that the set-up time is reduced so is cost effective and more efficient.

The Mistral 260 has three heat zones which can all be independently controlled ensuring accurate temperature profiles. It also has a viewing panel which allows our team to visually inspect the boards as they move through the oven on the conveyor belt.

The forced air convection provides uniform heating and prevents shadowing, minimised hot spots and cold solder joints.

NeoDen

The NeoDen is a 6-zone oven with heating elements and hi-tec sensors, the reflow oven ensures consistent and even heating throughout the entire length of the process chamber.  It has the potential to be pre-programmed with 16 different recipes ensuring high accuracy giving us more control on our product’s soldering quality.

The oven has a potential for up to 300ºC/572ºF temperature output without any chance of overshooting, allowing us the continued capability for using lead-free solder. With a maximum assembly clearance of 30mm/1.2 inches it gives us plenty of scope for our current and new products.  The offload zone cooling fans enable us to handle the boards safely immediately after the flown process has been completed.
