Although normal solder will melt at 180C ideal solder temperature is above 220C to get a good flowing and wetting behavior but below 280C to prevent burning of the solder.

Savbit solder with Ersin 362 flux has special MOD.
Ideal soldering temperature. Basic Soldering Guide. Controlling Heat Controlling soldering iron tip temperature is not the key element in soldering. The set temperature for a soldering station should be an additional 70C to 100C higher to provide a heat reserve for the quick thermal recovery of the tip after the solder connection is made.
Most solder melts around 180 to 190 degrees Celsius that is 360 to 370 degrees Fahrenheit. Better hot and fast than cold and long. Its a 6040 leadtin.
The Hot Bar must be set higher due to the thermal transfer losses. So here are the points to follow Set the time of a soldering tip temperature 100- 150 C or 212-312 F more than the melting point of the typical type of solders that you are working with. Divided into lead-based and lead-free types it is a useful reference for engineers and buyers.
The soldering temperature should be approximately 100 C above the melting point. Daz1761 October 23 2013 315pm 4. This temperature chart shows the different solders that are available and their melting temperatures.
This is usually between about 150C to 450C. That means a total temperature of 317 C. I say minimum 350 C With leadfree solder we have 400C on the tip.
The fluidity of low-temperature solders makes it possible to solder complex-shaped products. Not many people think about what temperature soldering iron for PCB is needed. But this should be the first step before undertaking any soldering activity.
To achieve good filling the contact time andor solder temperature should be increased. A typical solder such as 6040 with 60 tin and 40 lead has a melting point approximately between 183 C to 188 C. The melting point of soft brazing alloys is up to 300 C and has a tensile strength of 16-100 MPa and hard brazing alloys - 100-500 MPa.
A rule of thumb is you should be able to solder pads within 3 seconds. A good rule of thumb is to set the soldering iron tip temperature at 260 C - 500 F and increase the temperature as needed to obtain the desired result. Ideally time can be programmed on the SCU in 01-.
The recommended temperature of the soldering iron tip is at least 300 degrees Celsius. Why such a high temperature when the most com monly used solders have a melting point under 400F. There are few things that will impact the soldering temperature that you need on your soldering iron.
Using a higher temperature stores heat in the tip which speeds up the melting. A soldering station will give you the function of being able to set the temperature of the tip. 2 temperature-controlled soldering irons allow you to be sure that the soldering iron tip maintains the right temperature but they are more expensive than basic soldering irons.
At high soldering temperatures above 350C Multicore HMP alloy gives the best strength. As a general rule of thumb the optimal soldering temperature should be high enough so that when making a solder connection the solder is approximately 50C above its melting point. Here the recommended soldering temperature is 105 degrees Celsius.
But you cannot solder at this temperature. But what is the ideal temperature of soldering. Slower at normal soldering temperatures when Savbit alloy is used.
The melting point of lead-free solder is approximately 217 C. Depending on the conditions you may need to adjust the temperature of your soldering iron. The melting point of most solder is in the region of 188C 370F and the iron tip temperature is typically 330C to 350C 626F to 662F.
This number can vary for different soldering projects. 1 no temperature control designs which are usually the least expensive and suitable for household soldering jobs plug in and are ready to go after theyve warmed up. The higher temperature does compensate for the slower wetting exhibited with these lead-free alloys.
It depends on how accurate the temp control of your iron is and the soldering job. At lower temperatures cold solder joints and flagging are the normal. The best temperature range for a soldering iron is anywhere between 500 and 600 degrees Fahrenheit.
HMP SOLDER The presence of 15 silver substantially improves strength and wetting power compared to 595 SnPb. A soldering iron can reach temperatures of up to 450C. The key element is controlling the heat cycle of the work.
Above 800ºF issues of board and component damage may arise. Although tip temperature is not the key element in soldering you should always start at. The majority of soldering irons have three basic temperature designs.
Solder temperature was set at 250C for the tinlead assembly. The 340 350 o C orange is half. PCB Soldering Steps With some knowledge regarding what PCB soldering is various types of PCB soldering and the right tools for the job now lets shift attention to PCB soldering steps.
As mentioned earlier most solders melt between 180 190 degrees Celsius which is equivalent to 360 370 degrees Fahrenheit. You also have to take into account the tolerance of your soldering iron soldering. Selecting a Soldering Temperature for Your Iron.
So we have to get the solder joint hotter than this. With a cooler tip it takes longer time and the heat spreads over a larger area. When using 6337 solders temperatures as low as 650ºF have been used but with lead-free 700-800ºF is best.
When soldering live parts the specific conductivity of the solder must be taken into account. Soldering Iron Temperature Settings In order to raise the temperature of solder above its melting point soldering tip temperatures are usually set between 7000F and 800 0F. The wetting characteristics of lead-free alloys are less at the process temperatures than tinlead due to the higher melting points of the alloys.
