Description

Everything you’ll need to build a reflow oven with a convection fan (excluding the oven). The fan in convection ovens helps a small amount towards even heat distribution, but the primary reason to choose a convection oven is for the larger size. Convection ovens are bigger, but much harder to heat. The build guide isn't tailored to convection ovens. Most users prefer the regular build kit.

You'll need more of everything, especially insulation. They require a narrower piece of aluminum to mount the SSR's because the convection fan takes up a lot of space in the oven's control chamber. We supply everything you need to be able to control the convection fan.

The regular (non-convection) build kit includes the following...

  • Controleo3 Reflow Oven Controller with 4" touchscreen
  • ABS enclosure with UL94-5VA flame rating
  • Low-mass K-type thermocouple
  • Low-mass K-type thermocouple
  • Enclosure screws
  • 1/4" Braided sleeving (20" of red, 10" of black)
  • Rubber grommet (3/8" ID, 5/8" OD)
  • 1GB SD card
  • DEI Reflect-A-Gold insulation (2" x 6 feet)
  • DEI Floor & Tunnel Shield II insulation:

    • 10.5" x 8" (1 piece)
    • 10.5" x 6" (2 pieces)
    • 1" x 1" used as tray spacers (2 pieces)
  • 8" x 24" of 1/4" Superwool Blanket (ceramic fiber blanket alternative)
  • High-temperature silicone glue (3 Oz. = 85g)
  • 15" of Nomex high-temperature gasket to seal the oven door
  • Three 25A 380VAC Solid-state relays (SSR's)
  • 100mm x 100mm x 0.5mm thermal silicone pad
  • 5052-H32 Aluminum sheets

    • 8"x10-5/8" x 1/32" with 1/4" flange for PCB tray
    • 6" x 6" x 1/16" with 1" flange to mount SSR's
    • 1 1/2" x 3" x 1/32" for attaching Controleo3 to the oven chassis
    • 1/2" x 3" x 1/32" for the oven door servo
  • Servo kit

    • Powerful MG996R servo to open the oven door
    • Custom servo mounting bracket
    • Custom "bird's beak" servo arm
    • Aluminum servo disk with four M3-.5x5mm phillips screws
    • Miscellaneous servo hardware, including mounting screws
  • 5V 2A power supply
  • Stainless steel resistive heating element. Either

    • 350W@110V (400W@120V) or
    • 450W@220V (535W@240V)
  • Two 3/16" x 1 1/2" eye bolts with locking nuts
  • Ten #6-32 x 1/2" Phillips truss head machine screws with locking nuts
  • Eight #4 x 5/16" Phillips pan head sheet metal screws
  • 30" of 18 gauge 4-conductor wire
  • 20" of 18 gauge high-temperature silicone wire
  • Selection of zip ties
  • Heat shrink tubing (6mm diameter)
  • Six ring terminal crimps, two female spade crimps and a butt connector
  • $10 coupon to PCBWay

About Controleo3

Controleo3 is Intelligent

Controleo3's learning mode spends around an hour figuring out how well your oven was built and how well it performs. It learns how well your oven is insulated, how much power is needed to maintain temperature targets, how quickly your oven responds to requested temperature changes. It uses this information to accurately follow your custom reflow profiles.

Controleo3 is Customizable

Controleo3's flexible profile language helps you take charge of your oven's behavior. Write custom profiles to match your solder paste's datasheet, remove moisture from ICs, or even dry 3D printer filament.

  • Create and store up to 28 profiles in onboard flash memory
  • Write over 1000 instructions per profile to tailor your reflow experience
  • Add new profiles to Controleo3 using the SD card interface

Controleo3 is Expandable

Controleo3 provides both 5V and 3.3V (max 80mA) to power additional components. Output 6 is a microcontroller pin and can be used as either input out output. You can also tie into the SPI bus used by other components, like the MAX31856 thermocouple IC.

Controleo3's software is open source. Click here for the GitHub Repository.

The enclosure

Controleo3 uses a quality off-the-shelf flame-retardant ABS plastic enclosure with a textured finish. The holes are CNC machined to perfectly fit Controleo3. The result is a high quality, tight fitting case that looks very good

Technical Specifications

    • 32-bit ARM Cortex M0+ core at 48 MHz
    • 256 KB Flash memory
    • 32 KB SRAM
    • Custom boot loader (turns relays off during boot)
  • 1 MB flash for storing preferences and profiles
  • Support for full-size SD cards up to 32GB
  • 4" 480 x 320 color touchscreen display
  • MAX31856 thermocouple with line-voltage filtering and 0.25C precision

  • ABS plastic case - custom fit, flame-retardant (UL94-5VA)
  • Built-in servo support
  • Input voltage: 5V

    • The USB port should only be used for software updates and debugging. The USB port does not power the buzzer, the servo nor the relays
    • The servo is the largest current draw. We recommend using a 2000mA power supply
  • 6 relay outputs - relays are connected using screw terminals or the 6-pin relay header (4 outputs, +5V, GND). The outputs provide up to 220mA at 5V. The outputs support connections to solid-state relays (SSRs) or mechanical relays.

    • Output 6 is a microcontroller pin and can be used as either input out output.
  • Reverse-polarity protection on power terminals, and current protection on outputs
