Refer to the schematic at the bottom of this guide to see how the oven was wired. Perhaps I’ll add some of these items in the future if I want to use lead-free solder. The oven is performing well enough for tin-lead solder.

I chose not to spend any more money to add a 3rd heating element, Reflect-A-Gold tape, door gaskets, or a servo motor. When looking for a toaster oven to convert, it's best to keep it small and simple. This is the Hamilton Beach model 311-34 toaster oven I bought for $10 at my local Goodwill store. The minimal features of my oven bring the cost down to under $100.

5 volts DC is provided via a USB cable from a PC or power supply. The oven is powered from a plug strip with a switch.

The software tells me when to manually open the door during cool-down so there is no servo motor.

If a different solder profile is needed, new Arduino code must be downloaded. There is no power switch, touchscreen, or input buttons of any kind. An inexpensive Arduino Nano has just enough I/O’s to control two solid state relays (SSRs), read the temperature, and talk to a 16x2 liquid crystal display (LCD). With the lower melting temperature of leaded solder, I don't need to add a 3rd heating element. My requirements are not as challenging as Whizoo’s because I only solder one small board at a time and I use standard tin-lead solder. Besides, it’s a lot more fun to figure out my own design and learn along the way. I used many of the Whizoo methods for sealing and insulating the oven but I’m on a tight budget and can’t afford their kit. There are tons of examples on the internet but I believe the best one is from Whizzo. Contact us now.I’m getting too old to solder surface mount devices by hand so I decided to convert a toaster oven into a reflow oven. Need reflow oven equipment for your operations?

SPC (statistical process control) in the electronics manufacturing business helps assess if the process is under control, as measured against the reflow parameters established by soldering technologies and component requirements. Thermal profiling is the practice of measuring many places on a circuit board to detect the thermal excursion that occurs during the soldering process. This is sometimes referred to as condensation soldering.

The boiling point of the medium limits the highest temperature that assembly can attain.

There is no need for any protective gas (e.g., nitrogen), and there is no risk of assembly overheating.

Because of the high heat transfer coefficient of vapour phase medium, it has a high energy efficiency.

The following are some advantages of vapour phase soldering: The liquid used is chosen with the proper boiling point in mind for the solder alloy to be reflowed in mind. The heating of the PCBs is provided by thermal energy generated by the phase transition of a heat transfer liquid (e. As a result, nitrogen ovens often keep nitrogen infusion running at all times, which reduces failure rates. It takes a few minutes for the nitrogen reflow oven to lower the oxygen concentration within the chamber to acceptable limits. This reduces oxidation on the soldering surfaces.

Nitrogen (N2) is a popular gas for this purpose. Some ovens are made to reflow PCBs in an oxygen-free environment. Ovens that employ both infrared radiative heating and convection heating are referred to as ‘infrared convection’ ovens. Because PCBs and components differ in infrared absorptance, indirect heating using air allows for more precise temperature control than direct heating with infrared radiation.

They may be fan-assisted in order to adjust airflow within the oven. The heat source in infrared reflow ovens is typically ceramic infrared heaters above and below the conveyor, which deliver heat to the PCBs by radiation.Ĭonvection ovens heat air in chambers, which is then used to transmit heat to PCBs by convection and conduction. Types of reflow ovens Convection and infrared ovens The profile used may change based on the needs of the PCBs being processed at the moment. To obtain a given time and temperature profile, technicians modify the conveyor speed and zone temperatures. PCBs are treated at a regulated rate as they pass through the oven and each zone. In commercial high-volume application, reflow ovens have the shape of a lengthy tunnel with a conveyor belt that transports PCBs.Ĭommercial conveyorised reflow ovens include numerous separately heated zones that may be individually temperature adjusted. A reflow oven is a machine that is mainly used for the reflow soldering of surface-mount electronic components to printed circuit boards (PCBs).
