![]() It's got to be better than just two, right?ĭon't immerse in water?!? Damn. Notice the two heating elements on top and bottom. The front control panel - soon to be circumvented. The lights dimming across my house gave me a fuzzy feeling in my stomach as well. A dry-run test proved this baby can heat up like crazy. I think I paid $60 at Target (local chain - basically WalMart) for this guy : ![]() But first, we must purchase and immediately destroy a perfectly good toaster oven! That's where the Reflow Toaster Controller comes into play. ![]() By the way, this reflow oven didn't work.Īll we aim to create is an embedded system that takes in temperatures and actuates a relay that controls the heating elements - effectively controlling the temperature. Picture of the premo profile off our $2300 reflow oven. This is all because of a posting on the SFE Support Forum. All that is needed is a controller to heat the toaster to a specific profile. This is hot enough to melt solder paste allowing home hobbyist the ability to 'cook' PCBs. A toaster can hit 230C with relative ease. These cheap-o units from Tar-chez can cost a meager $50. Don't eat from a toaster oven that's cooked PCBs. Isn't it time for you to upgrade that 56k modem? My apologies to all users still on slow connections.Īll the usual warnings apply: A toaster oven can kill you. I heard Hong Kong is going to Gigabit internet connections. And I'm too impatient to wait for the v2 PCB.Īs usual, there are quite a few photos. Basically, I just want to share the information I have obtained and the layouts I have created. Well, at least not in our 110V fire starter. We are only here to re-hash and hopefully educate those in the art of toasting.Īs of writing - we haven't reflowed anything. There are many more knowledge individuals that pioneered the field. We have really built upon the shoulders of others here. Yes, we have our own reflow oven that cost 30 times as much. Yes, we know others have used toaster ovens for reflow soldering purposes. This post is a contribution of RobotDigg offers motorized and linear Delta Robots, Cartesian XYZ, SCARA, SLA 3D Printer, Benchtop Surface Mount, CNC Laser, Robotics and many more products.If you've ever played with SMD devices, you know what a pain it can be to solder tight pitch pins. The most popular desktop reflow oven from RobotDigg China Inert ball screw and guider – Every week – Dupont Krytox GPL227. ![]() PCB carrier chain – Every day – Dupont Krytox GPL107.Timing chain, bearings, and tension pulley.Head sprocket, bearings and adjustable chain – Every Month – Calcium-based lubricant ZG-2.The following table is a typical lubrication schedule example:ĭescription – Period – Recommended lubricant Vacuum the chamber and remove the flux residue and soldering balls.Clean the ventilation pipe with a cleaning agent.Once the chamber temperature decreases to room temperature, open the hood and clean the inside surface of chamber with a proper cleaning agent.Clean the photoelectric switches which detect whether a board is within or outside of the reflow oven.Check conveyor chains, sprockets, mesh and the automatic lubrication system.Clean and wipe down the machine daily.The following is a list of daily, house-keeping tasks to be accomplished for maintaining a reflow oven: This will cause inaccurate thermal data readings and the thermal controller will make the wrong adjustment instructions. Although there is a flux collection system in modern reflow machines, there still is a big probability that flux will adhere to the inert air ventilation pipe and thermal regulator panel. One of the most important tasks for properly maintaining a reflow oven is remove the built-up flux residue inside the oven’s chamber. Proper reflow oven maintenance can extend its life cycle, keep the machine in good condition, and improve production efficiency and product quality.
