The substrate is pre-tinned with solder using solder paste, molten solder dipping, or solder preforms; The capacitor-substrate assembly is heated to the solder flow point temperature to form a well-formed solder fillet; The assembled substrate is cleaned with a mild solvent (usually ultrasonically) to remove flux residues
To remove components like this from motherboards is not easy, the biggest problem is lack of sufficient heat to melt the solder all the way through the hole, this is due to copper planes taking the heat away and acting as …
The tip of a heated soldering iron is pressed against the hole to melt the solder; Keeping the bulb against the hole, the bulb is released (unsqueezed) either with the soldering iron in place or just as the iron is being withdrawn. I''ve found both techniques helpful depending on the size of the hole and amount of remaining solder.
4. Remove Molten Solder. With the solder molten, use a desoldering vacuum pump or solder sucker to remove the liquefied solder. Position the solder sucker tip near the lead and press the release button firmly to vacuum the melted solder. Act quickly while solder remains molten to remove it fully from the joint. Avoid excessive …

What iron/tip, hot air and solder. Adding a dab of fresh solder is always good practice but if it''s not flowing there simply isn''t enough heat getting to it. Yet, too much heat from an iron can pull pads and destroy things. It''s a careful balance so you don''t want to just crank the iron to 450c and smash away...but the solder used is clearly "dry".

Capacitors option 1: Google ''capacitor repair kit BRAND MODEL'', there are a bunch on ebay ; Capacitors option 2: For individual capacitors Digikey is a good source, get the same or greater voltage rating and same or greater capacitance; Soldering iron ; Solder ; Flux ; Solid core insulated copper wire, cat 5 riser cable works well.
To use it, simply hole it up the the joint you want to remove solder from and hold a soldering iron up to it. It should soak up the solder fairly quickly. If not, then you probably have poor quality solder wick.

To remove components like this from motherboards is not easy, the biggest problem is lack of sufficient heat to melt the solder all the way through the hole, this is due to copper planes taking the heat away and acting as heatsinks, you need an iron with a much higher temperature than normal so you can remove the solder quickly and effectively ...
Step 4: Remove the Faulty Capacitor Using a Soldering Iron. Using a soldering iron, gently heat one of the capacitor''s terminals to soften the solder. Repeat the process for all four terminals. Once the solder is liquefied, use a desoldering pump or wick to remove the softened solder from the terminals.

The same is true for desoldering, apply some flux to remove contaminants. ... Please note, these temperatures are melting points, not recommended soldering or desoldering iron temperatures. Most guides recommend starting with the lowest temperature that will work in a short amount of time. This is a matter of opinion, but generally no less than ...
The failure of a capacitor is the amount of energy lost as a result of the capacitor''s action under alternating voltage and is represented by a loss tangent. These losses are normally higher than dielectric losses and are linked to losses on the electrodes as well as the temperature or frequency of the capacitor circuit.
If you are trying to rescue random components from old circuit boards, I''m guessing you might not interested in spending hundreds on new equipment. I can give you a few tips when it comes to removing things with a simple soldering iron, solder, and some tweezers. Two terminal devices are not too difficult, especially if they are small.

Maintain a gentle press on the braid using the tip of the soldering iron. Keep the contact till all the flux is absorbed by the copper braid. Do the same for the other pad. Finish off by cleaning the pads in a piece of cloth dipped in alcohol. Step for Regular PCB Capacitor Desoldering. Plug in the soldering iron and set the temperature to 370 ...
4 Apply soldering braid to the base of the capacitor where the leads are soldered to the circuit board. 5 Press the fully heated soldering iron against the braid so that the solder heats up and is drawn into the braid. Continue this process until the solder is removed from the capacitor leads. 6 Pull the capacitor free from the circuit board.

1. Use a soldering iron with sufficient wa ttage and a regulated temperature. The adequacy of the soldering iron can be judged by the amount of time needed to reflow the solder. …
Solder Wick is basically just copper braid that soaks up solder when you heat it up. Good solder wick should always have flux in it. To use it, simply hole it up the the joint you want to remove solder from and hold a soldering iron up to it. It should soak up the solder fairly quickly. If not, then you probably have poor quality solder wick.
It''s best if you dip the soldering iron in some flux before you do this. Keep on pressing the soldering iron on the solder until the solder melts entirely. If you don''t have a solder braid or a desoldering pump, then use the soldering iron itself to remove the solder. Push the solder away with the tip of the soldering iron, and then nudge the ...
