Why is my solder not flowing?
Heat is the number one reason that solder flows. Without it, you'll unsuccessfully try to solder a piece for a very long time. Heat is a tricky thing to figure out, especially if you're just starting out.
Can you use steel wool to clean a soldering iron?
Take a steel wool pad and dampen it slightly, then scrub it over the iron's tip to remove rust and any other heavy staining. Steel wool is the only cleaning item safe to remove rust or stains with. Avoid sandpaper, which is too corrosive for solder iron tips.
Why does my soldering iron not melt solder?
Solder has a very low melting point (compared to other metals/alloys). Even a weak 40W iron should melt it almost instantly. If it's not melting the solder, then the iron is not hot enough or even working. Try poking the tip through a piece of paper.
Should I sand my soldering iron tip?
Is the tip dull and brown, or does it appear oxidized or rusted? This is where you might need the sandpaper. Wait until the iron is cool, and sand the tip until you start to see some shine again. You don't want to remove the metal of the tip — just the oxidation layer that prevents it from heating properly.

Can you remelt solder?
Try putting some fresh solder on the tip of the iron and see if that helps. Your new ground can be connected anywhere on the back of the pot. You could even just clip the old wire and put the new one next to it if you're unable to get all of that solder off.
Does flux help solder melt?
The solder paste flux also contains additives to improve the flow characteristics of the solder as it melts.
Why can't I get solder to melt?
Solder has a very low melting point (compared to other metals/alloys). Even a weak 40W iron should melt it almost instantly. If it's not melting the solder, then the iron is not hot enough or even working. Try poking the tip through a piece of paper.
How do I test my soldering iron?
The operator places the heated tip of the soldering iron onto the metal tab with a small amount of solder to ensure a complete connection. The resistance is recorded. If the recorded voltage and resistance are below a number stated in ESDA ESD STM 13.1-2000, the test is considered to pass.
How do you test a soldering iron heating element?
A reading of several thousand ohms or more would be indicative of a burned out heating element. On the 1A soldering station the heating element is connected between pins 1 and 2 on the soldering iron receptacle. If the resistance measures correctly, the temperature sensor should then be measured.
How long does it take for soldering iron to heat up?
My (also 25 W) says that 1 minute is needed to reach operating temperature. The heat transfer also depends a lot on the condition of the tip. If the tip is bad, then it could take a while for it to melt solder even if the temperature is reached.
Step 1
Open the soldering iron Carefully. confirm you're not giving extra pressure to the Soldering tip. Otherwise, the Soldering Tip may Break.
Step 2
Here you'll see all the components from the soldering iron. Here you'll also see a Physically Damaged IC. This must be a Triac for voltage regulation. The circuit is like an LED Dimmer Circuit which I even have made previously.
Step 3
Then I removed the SMD Triac with a Hot Air Gun. If you don’t have this then you'll also use another soldering iron. for removing the Triac.
Step 4
Here you'll see it's written BT134. it's a Triac. So, My assumption was correct. this is often an SMD Component. In my local market, only THT components were available, SMD wasn't available. once I saw some datasheets then I find that BT136 is best than BT134. By the way, BT136 is widely available within the market at the lowest.
Step 5
Then I soldered the BT136 and put it to in its Enclosure. and eventually , the soldering iron is prepared to use.
What to do when soldering iron is broken?
After doing this, confirm that any conductive materials or wires are far away from the working area. Doing this is important if you want to prevent an accident while fixing the broken soldering iron.
Why isn't my soldering iron tip breaking?
This isn’t recommended because heat doesn’t rise when the tip gets forced, and instead, this only causes it to break.
Why use a wet sponge on soldering iron?
It’s also advisable to use a wet sponge when cleaning the soldering iron tip to avoid excessive friction.
How to recondition a solder tip?
You should recondition the soldering tip by connecting your soldering iron to a power outlet and giving it enough time to heat up. Once the soldering iron gets heated under ordinary soldering condition, dip the soldering tip into the now open Plato Tip Tin TT-95.
How long will a soldering iron last?
With regular cleaning and preventative maintenance, your soldering iron will remain useful for many years to come.
Can you use sandpaper to clean soldering iron?
It’s best to stop using materials such as sandpaper when cleaning your soldering iron. Ensure the solder being used is always of exceptional quality. It would be best if you avoided poor quality solder as it contains lots of impurities that accumulate on the soldering iron’s tip over time.
Can you expose soldering iron tip to flux?
Confirm the tip of your soldering iron is fastened properly should you opt to replace it. It’s recommended not to expose the soldering iron’s tip to flux, which might be corrosive and leads to the tip getting destroyed over time.
Why do soldering tips crack?
Soldering tips are delicate and prone to cracks, especially if you are applying excessive pressure on the surface. Inexperienced operators are known to press the tip hard on the joint surface when applying solder, causing cracks. Cracks also develop as a result of dropping the iron on a hard surface. The cracks cause the tips to deform and bend, ...
What type of tips are used for soldering?
Fine tips are ideal for soldering delicate surfaces and not heavy-duty soldering jobs. Broad tips are suitable for any given job. Experts advise using chisel-shaped tips and not conical-shaped tips. Also, when soldering lead on Gull Wing or J Led components use the GW tips along with liquid flux.
What causes a plating tip to deform?
The cracks cause the tips to deform and bend, making the plating layers to exfoliate. Also, the surface of the tip becomes exposed to oxygen, moisture, and tin, which accelerates oxidation and erosion.
What causes cracks in lead free solder?
Most lead-free soldering applications need high processing temperatures, which expose the tip to high temperatures. Wiping the hot tip with a wet cleaning sponge creates shock which may cause cracks to develop on the plating layer.
What temperature should I use for soldering copper?
Avoid using extremely high temperatures when soldering, i.e., 427 degrees Celsius or 800 degrees Fahrenheit. Higher temperatures increase the probability of the formation of iron oxides. Use an adequate amount of solder: too much solder wears out the tinned tip surface and increases the exposure of the inner copper.
How to fix a cracked iron?
It also minimizes exposure beyond the surface of the tip. Then, tilt the tip and align it to the pointed part to restore its shape . Use set screws to re-assemble the iron. Fit the tip back to the heater assembly once you have achieved the desired shape.
What happens if you don't use an iron on a funnel?
If you fail to do this, the iron may bang against the funnel spring.
What is soldering iron?
A soldering iron is a tool with a metal tip that gets really hot. We’re talking like 800 degree Fahrenheit, though you can adjust the temperature on a good iron. Its job is to transfer heat to things like wires, transistor leads, and pads on PCBs. After the appropriate areas are heated properly, solder is applied.
Why do you need to clean and tin a soldering tip?
(Image credit: Mae Labs) In order to conduct heat properly, your soldering iron needs to be free of any old solder. After being exposed to air, it oxidizes and thus insulates against heat. We want heat to conduct so that we can apply everything quickly and efficiently.
What does a dirty tip mean on a soldering iron?
A dirty tip means that you’ll have to hold the iron on longer and risk heat damage to the PCB, and nobody wants that. Keep a wet sponge handy, and after the soldering iron is fully heated, softly scrape it against the sponge to remove old solder. The tip should be nice and shiny, or at least very close to it.
What does a bad solder joint look like?
It cools very quickly, but moving or blowing on the joint will cause it to deteriorate. A bad solder connection will look really oxidized, overly dull, and grainy. It also sort of looks like a ball of solder formed on the area. A good connection should be smooth and uniform, and its sides will be concave.
What is solder made of?
Solder is a thin tube, usually rolled in spools, made of various metal alloys. Its job is to hold the individual components together. The individual components and their quantities can vary, but for computer electronics, you’re usually looking at a 60% tin and 40% lead. Lead-free solder is also available, though it has higher melting temperatures ...
How long does it take to remove solder from a joint?
This allows the solder to continue to melt and pool, forming a good joint. Then, you can remove the iron. The total process shouldn’t take more than 5 seconds, and usually you’re aiming for 3-4. Wait a few seconds and don’t disturb the solder.
Is lead free solder better for the environment?
Lead-free solder is better for the environment and has other benefits, and they function more or less the same way. The inside of the tube is filled with “flux,” a substance that gets rid of oxidation and helps clean the surfaces involved in the fusing process. For electronic use, you want rosin-core/rosin-flux solder.
