Reflow Soldering Oven

Reflow Soldering Oven

A reflow oven was needed at SNT for a small batch of Production PCBs. I looked into buying new and used reflow ovens, but none of them matched a price point for the needed low production quantity. So to the internet I went! The controller I selected was from Whizoo.com.

After 'testing' the pizza oven for its original purpose: 'gourmet' meals it was converted to be a reflow soldering oven. The oven was chosen specifically for this task, and was chosen because of the large number of heating elements (3 on the top, one on the bottom) and because, being shaped specifically for pizza, it has a unique size that bodes well with the type of 'Cooking' we will be using it for, namely large surface area and minimal air volume. 

After disassembling the oven, solid state relays were added to control the heating elements.

 

The chamber was sealed with reflect a gold thermal tape to keep the heat in as much as possible.

More insulation tape and insulating boom mat were added to the oven along with a 5th heating element

A Controleo2 was mounted to the top to control the heating elements instead of the built in timers.

More insulation was added to the top and sides of the oven to keep the hot air inside from leaking out.

Finally the top was put back on and the oven was setup.

The servo mounted to the Controleo2 pushes open the door to help cool the oven. A hose clamp was used to assist the servo in opening the door.

The oven is fired up and calibrated. Many thanks to the people at Whizoo.com for the great controller and build guide!
