How To Reflow Solder

Solder Paste Component Manufacturers.

How to reflow solder. 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. If playback doesnt begin shortly. If there is too much paste then a component can swim or float on the solder during the reflow process.

Below in Figure 1 is an example of an Alpha OM-353 SAC 305 Lead Free profile graph. Silk screen are pretty inexpensive these days. Now apply heat to the base of the LED star mcpcb till the solder melts.

There are several sources for how a reflow profile graph should look like. For the first step the deposit of solder paste you need a silkscreen. Its best if the warm up takes at least 10-20 seconds from start to melt.

Wave soldering on the other hand is generally preferred for attaching multi-leaded through-hole components to circuit boards that are designed for surface-mount components. 2- position components on the board. Reflow soldering is a process in which solder paste is applied to the contact pads of a PCB and melted to join the electrical components.

The real process encompasses the flux minimizing the surface tension especially at the metal junction to achieve metallurgical connection. A common heat gun is an inexpensive way to reflow or reattach electronic components that have been soldered together. New to soldering.

3- put the board in the oven and heat it. Start the process by applying flux to the pads to make sure they are clean and will get heated properly. The reflow section entails the part in the soldering process whereby the ultimate temperature is achieved.
