How To Reflow Solder

The most common are solder paste and component manufacturers.

How to reflow solder. The reflow section entails the part in the soldering process whereby the ultimate temperature is achieved. There are several sources for how a reflow profile graph should look like. If there is too much paste then a component can swim or float on the solder during the reflow process.

The reflow soldering technique resembles the traditional soldering process in many ways. A common heat gun is an inexpensive way to reflow or reattach electronic components that have been soldered together. New to soldering.

The process of reflow soldering involves attaching components to metal pads on a circuit board with solder paste and then subjecting the entire unit to heat. The real process encompasses the flux minimizing the surface tension especially at the metal junction to achieve metallurgical connection. Saying the magic spell meltum meltum meltum move the nozzle back and forth until the solder begins to flow the solder should appear shiney and molten.

But the one major difference is that it uses heated air to melt the solder instead of a soldering iron. Start the process by applying flux to the pads to make sure they are clean and will get heated properly. Kapton Film stencil to apply solder paste over PCB pads.

A metal one can cost around 10 when you order your PCB and a milar one is even cheaper. No problem check out basic soldering tutorial and surface mount soldering guides. EASY - How to reflow solder a circuit board.

Stencil Design Solder Paste Deposition. Solder balling occurs if the solder paste spatters small explosions during reflow or if the paste slumps and the flux spreads carrying away solder particles which cannot reflow back into the solder mass. You can also use reflow ovens to solder through-hole components simply by filling the through-hole holes with solder paste and inserting the component leads through the paste.
