Turn on the soldering iron and set temperature above the melting point of your solder.
600°- 650°F (316°- 343°C)
is a good place to start for lead-based solder and 650°- 700°F (343°- 371°C) for lead-free solder.
How do I know if my soldering iron is too hot?
Your iron is too cool if you don't get a free flow of solder leading to a shiny surface and a good meniscus shape, or if you create icicles Your iron is too hot
if the solder melts too fast
, and in using SMD parts, if the solder at both ends of the part melts when you apply the iron at one end.
How hot should soldering iron be for desoldering?
| Device Setting | Soldering iron 330 to 360°C (630 to 680°F) | Hot air rework station 350 to 380°C (660 to 720°F), with low to medium airflow. |

What temperature does solder melt at?
Alloys that melt
between 180 and 190 °C (360 and 370 °F; 450 and 460 K)
are the most commonly used. Soldering performed using alloys with a melting point above 450 °C (840 °F; 720 K) is called “hard soldering”, “silver soldering”, or brazing.
Can a soldering iron overheat?
Overheating the tip
Your soldering iron should
be set to +100°C of the solders melting point
. The tip will be oxidized if you overheat it. The tip gets black and solder is not sticking to it anymore. It just drips off.
How do I know if my soldering iron is on?
It should still be
shiny
if you've done it right. As soon as you tin the tip you should start soldering your components together. After every few joins, clean and re-tin, and again before putting your iron away into storage.
Why is too much solder bad?
Cold Joint
The solder bond will be poor and the cracks may develop in the joint over time
. … The excess solder can usually be drawn-off with the tip of the iron. Prevention: A properly pre-heated soldering iron with sufficient power will help prevent cold joints.
What do you do if solder won't melt?
One good way to get a tight fit between the two parts is to squeeze them closed then saw through the gap which takes off a sliver but makes for a good tight fit. Slosh the flux around and flux the solder. make sure it
all gets hot enough
, if the solder isn't melting at all you simply are not getting enough heat.
Is it necessary to use a soldering iron when desoldering?
Using the tip of the soldering iron will remove the copper plating from the PCB. Pros: You need nothing but a soldering iron, and
the components can be reused
. Cons: You may damage the board if you leave the soldering iron on it for too long.
Do you need flux to solder?
Yes,
solder can be used without flux
. To do so, you will need something other than flux to break down the oxides on the metal surface, without which your surface may be damaged or not properly cleaned.
Can you use too much flux when soldering?
Although there is a sufficient amount of flux present in the core of the solder wire to get your job done, the technicians (to make their job easy) tend to use additional flux in form of paste or liquid during the rework on the PCB.
There is no problem with the use of flux during soldering
.
What temperature should I set my soldering station?
Turn on the soldering iron and set temperature above the melting point of your solder.
600°- 650°F (316°- 343°C)
is a good place to start for lead-based solder and 650°- 700°F (343°- 371°C) for lead-free solder. Hold the tip against both the lead and contact point/pad for a few seconds.
Can you reflow solder with a heat gun?
A common heat
gun
is an inexpensive way to reflow, or reattach, electronic components that have been soldered together. … Before you begin soldering, make sure that all the small components on your board are held down; the heat gun produces a lot of air that can blow these parts away.
How do I check the temperature of my soldering iron?
To measure soldering iron tip temperature, we recommend the use of a
Hakko FG-100 Tip Thermometer or Hakko FG-101 Station Tester
. For the purpose of this article, we will use a Hakko FG-100 Tip Thermometer.
What temperature is a 40 watt soldering iron?
Power consumption: 40W. Max. Temperature:
860°F (460°C)
Can you file down a soldering iron tip?
Never file a soldering tip
. Filing it will remove the protective layer, allowing the metal underneath to be eaten away by solder resulting in permanent damage over time. Tin it immediately once it first starts heating up, and every few times you use it as required.
