REFLOW SOLDER OVEN PROFESSIONAL

Look for solder bridges, misplaced components and bad/non-existing solder joints.įor very small parts you can use a USB microscope or a magnifying glass. When the circuit board has cooled, inspect it to see if everything looks okay. Here is a couple of external links with more specific information: This will activate the flux in the solder paste in order to remove the oxides on the metal soldering surfaces. Soak: Once the board reaches the first designated temperature, it will remain here for a predetermined period. Just get the board hot enough to make the solder melt, then cool the board. The solder reflow process generally follows this pattern: Preheat: This brings the board up to its first designated temperature. This can easily be done with a toaster oven or a skillet.

Raise the temperature gradually up to 220 degrees and let it stay there for 1-2 minutesĪs mentioned earlier, you don’t need an industrial type of oven to do this.

Preheat the oven to ~ 100 degrees Celsius.

I happen to be so lucky that I have a reflow oven in my office :) This is the process I use: Usually a peak temperature of 220-250 degrees Celsius is used.īut in the hobbyist world, we just find something that works )

REFLOW SOLDER OVEN PROFESSIONAL

In the professional world, a specific temperature profile is used to ensure that the solder melts properly and that the components aren’t damaged from the heat. The basic idea is to heat the circuit board to a temperature where the solder melts, then let it cool. With all the components in place, you are ready for the reflow process. When the solder melts, the components will usually align on their own, but try to align them as precise as possible in advance anyway. Capital Equipment Exchange has a range of used wave solder machines and used reflow ovens to help you increase production and solder components to your. Now, take out your surface mount components and start placing them one by one using your tweezers. At least most of the times ) Place components When it melts, it will flow naturally to where it belongs. You don’t need to be too precise with applying the solder paste. Apply solder pasteĪpply a dash of solder paste to each of the pads.

Start the process by applying flux to the pads to make sure they are clean and will get heated properly.

To do reflow soldering, you should have the following tools: But is this something you can do as a hobbyist? Reflow soldering is a very effective method for soldering circuit boards with lots of surface mount components.
