Can you Desolder with a solder?
Step 1: How to Use a Soldering Iron to Desolder If all you have is a soldering iron, then your only option is to heat up the solder and fiddle with it until you can get the components out. Heat up the solder with the iron. 2. Slide the iron up the pins to bring the majority of the solder away from the joint.
What will dissolve solder?
Fluroboric acid (0.3M) with hydrogen peroxide (0.2M) selectively removes solder quite nicely.
Do you need flux to Desolder?
When desoldering, you should apply flux to whatever the solder is supposed to wet to. If you are using a copper desoldering braid, then apply a bit of flux to it.
What kind of solder do you use to desolder?
If you are desoldering something that has been soldered with lead-free solder, add some leaded solder to the solder joint. Leaded solder has a lower melting point than lead-free solder. Mixing it in lowers the overall melting temperature and makes desoldering easier.
How do you remove solder from a desolder pump?
1. Heat up the solder you want to remove with a soldering iron (some desoldering pumps also come with attached irons). 2. Press down on the plunger (If your pump has a bulb, just squeeze the bulb). 3. Once the solder is molten, place the tip of the desoldering pump against the solder that you want to remove. 4. Release the plunger or bulb.
How to solder and desolder an iFixit connection?
1 To solder each connection: 2 Place the tip of the soldering iron against the solder pad. 3 Melt just enough solder onto the solder pad so that the capacitor’s contact lead holds firmly in place. 4 Remove both the solder and the soldering iron tip from the connection as soon as enough solder melts onto the pad.
What happens when you desolder copper with solder iron?
When you place desoldering braid over a solder joint and heat it with a soldering iron, the solder of the solder joint melts and the flux of the desoldering braid activates. As a consequence, the solder flows from the solder joint up into the braided copper through capillary action.
