![]() ![]() A $50-$100 toaster oven from your local Wally World can do quite nicely. Using a toaster oven has been shown to work in many cases. Heat stressing can lift pads if the soldering student is new to soldering.Boards get dirty with all the flux running around.Soldering equipment most likely to be available.Over all, hand soldering is the way to do it when other means are not available. Soldering from the back side of the PCB using vias as heat ducts has worked for other people. But get creative! All you have to do is heat up the overall area. The only exception is BGA which I've never tried with an iron. It's not easy and not fast, but it can be done. No really, you can! No matter how small the pitch, even leadless QFN packages, can all be soldered with some solder wick and some solder ball chasing. I certainly can't hand solder XY type package!.A heftier tip can be beneficial in some cases (helps to move solder blobs). Don't even think about trying it with your $10 Radio Shack fire starter! But a conical tip of small size works fine. With a little practice, we can see disconnects and color variations that indicate problems with the naked eye. Believe you me, it can all be hand soldered. New users to soldering SMD devices are always intimidated by soldering itty-bitty leads. $100 is pretty standard for an iron although $50-$2000 is possible. You will need a decent iron, but nothing else. ![]() Hand soldering is cheap (no extra equipment needed). There are five ways to solder SMD parts that I can think of: Well, just take everything we say with a grain of salt. Don't try any of this at home - wait, you are at home. Here is a tutorial that will break down the different approaches to SMD reflow soldering, what we've learned, and what to steer clear of.Īs always, this stuff can kill you, burn your house down, or make your basement smell pretty foul. If you're reading this, you're like us - strapped for cash and in need of a good way to reflow PCBs. I'm here to tell you, it was all a waste of money.ĭon't get me wrong, there is the correct way to manufacture 10,000 units of a caller-ID controller board, and then there is the Spark Fun way. ![]() Luckily, as business has increased, revenue has allowed us to purchase a few bottom-dollar machines to help with manufacturing. Spark Fun has barely had the capitol to invest in a hot-air rework station, let alone pick and place machines and industrial reflow ovens. For shorter catheters, the spring-loaded catheter clamp can be lowered to ease loading.I've been reflowing SMD parts on PCBs for around a year now. Yet it can process catheters up to 170 cm long. The vertical reflow machine stands at 7’ tall and takes up only 2’ x 2’ of floor space. This reduces power consumption and eliminates heating the room. The heater automatically starts at the beginning of a cycle and shuts down at the end. Selectable operator mode locks out process parameters for error-free operation and a more streamlined start-stop workflow. From the main screen, users can easily home, and adjust all process parameters. Precise position and speed control round out the features that ensure repeatable results.Ī 7” color touch screen offers intuitive control. A pair of independently programmable centering clamps close to consistently center your device in the nozzle to ensure even heat distribution. The temperature is programmable up to 300° C and is maintained within 1° of the setpoint. The proprietary 360° convection nozzle delivers precise PID controlled hot air to your device. It plugs into a standard 120 VAC outlet so it can be used where you need it. This machine combines flexibility with accurate and repeatable performance. This vertical reflow machine is perfect for prototyping and pilot production lines. ![]()
