If the iron plating on a soldering tip is damaged, it can lead to problems with the soldering performance. A crack or hole in the plating will allow the copper interior of the tip to come into contact with the solder. When this happens, the copper will dissolve into the solder, impacting...
This requirement to remove lead from solder has resulted in solder compositions with higher melting temperatures. Designers must now use PCB materials that can withstand these higher temperatures without damage. In addition, the thermal profile of lead-free solder must now allow the board to reach ...
Remove excess solder from lands. Remove solder from BGA pads. Place braid over the solder to be removed. Place the iron tip on the braid. Allow heat to conduct through the braid to melt the solder. The braid will absorb solder using a wicking action. Use caution holding the braid, as ...
SOLUTION: A lead-free solder material that produces a Cu Sn metal-to-metal compound is applied to a joint after coating a soldered portion of a substrate to be joined with a lead-free solder alloy containing Sn or Sn as a main component in advance. It is a solder joining method in ...
If you don't have access to a hot air rework station and just need to remove it you can use a hand soldering iron. The first step would be to lift all of the pins off the solder pads. Then you will need to clip/ cut the body of the connector in order to expose the center stri...
How to Solder Flashing LED's on a Blank PCB: A PCB is an acronym for " Printed Circuit Board ". On a PCB you will A PCB has holes where you can slip in the component and on the flip side, you can solder the legs of the components in order to keep them i
I guess you could do that on a pad with heating it up and putting lead-free solder on it then wicking it off and putting some more lead-free solder and wicking it off. Two things, one it is a dilution effect, so you are never going to get all of the lead off and could you ...
For instance, the melting point of a leaded solder is less when compared to a solder that is lead free. This is why you need to use a lower temperature when trying to remove any SMD component. Furthermore, when taking out the SMD chip with the hot air, place the temperature within the...
If that does not work move to medium activity flux and then remove any leftover flux with Isopropy Alcohol. Make sure the leads are free of any flux. Use a solder pot to tin the leads to check for solder adhesion. Edithel Marietti Senior Manufacturing Engineer Northrop Grumman Edithel ...
Different solder behavior: Lead-free solders often have poorer wetting characteristics, making rework more challenging. The higher surface tension of lead-free solders can make it harder to remove components. Component considerations: Some components may not be rated for multiple exposures to lead-free...
