6. Soldering with a Solder Iron Attachment by soldering iron is not recommended. A heat shock may cause a crack in the MLCC chip capacitors, however, if solder iron is used, the following precautions should be taken: A. Preheat the chip capacitor to +150 °C minimum. Use hot plate or hot air flow for preheat. B. Use a low wattage, temperature ...
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.
Hold the replacement capacitor in place using tweezers and solder the first leg using the solder that is already on the pad, plus a small amount of solder loaded on the iron tip, to avoid the need to feed in additional solder from a spool. We only need small amounts here. Repeat for the second leg, for which the cap should sit in place on its own.
It''s not the solder, it''s the fact that the heat from the sodldering iron is going into the ground plane or the +V bus, both of which are relatively large sheets of copper. You need to get the heat from the iron going into the leg of the cap …

Leaded film capacitors are not suitable for reflow soldering. In order to ensure proper conditions for manual or selective soldering, the body temperature of the capacitor (T s) must be ≤120 …
Soldering Temperatures during hand soldering operations: Polypropylene capacitors can be easily damaged by hand soldering processes as well. Care must be taken in the soldering iron/tip selection. The iron/tip should be large enough to accommodate the soldering process, yet small enough to prevent damage to the capacitor.
The capacitors and substrate are prepared by cleaning with a mild solvent and pre-fluxing; 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
put the capacitor in place and practice holding it down firmly but gently with a thin piece of wood or some strong thin cardboard with your non-dominant hand. Rotate the board so it feels comfortable. collect a blob of solder about 1 mm deep on the tip of the iron; touch the solder to one side of the capacitor and hold it for up to 2 seconds.
Make sure your soldering iron hasn''t just gone to sleep and needs to heat up a bit. Some Irons can do this to save wear and tear on the tip. You may be trying to feed solder to a part of the tip that is cooler than other parts. The side of a conical tip is the best place to feed the solder and to hold against the joint; the sharp tip may be too ...
Just because solder is molten on the surface it doesn''t mean it is same temp inside hole. Plus it cools very quickly. The best approach is to heat the area (several inches) around the holes with a hot air gun or board warmer. Not hot enough to melt solder but too hot to touch. Then was the soldering iron can work better.
While adding a new lead to a pcb board by soldering iron touched one of the electrolytic Capacitors, and melted the plastic casing of the Cap. Should I replace this Cap? Skip to main content. ...

Keep your iron there. Let the solder melt and meet and mingle with the solder that''s in the hole. When it all looks fluid, gently stick the tip of the wick right into the crux of where the iron meets the pad and into the solder blob you just made, and wait a few more seconds.
Soldering Iron. Ceramic capacitor attachment with a soldering iron is discouraged due to the inherent process control limitations. In the event that a soldering iron must be employed the following precautions are recommended. Preheat circuit and capacitors to within 100° C of soldering temperature; Never contact the capacitor with the iron tip

My soldering iron allows to set a delay after which it cools down, you shake the handle to reactivate it - it too has an audible little ball inside it. ...
If the capacitor reads as having fewer than 10 volts, you don''t need to discharge it. If the capacitor reads anywhere between 10 and 99 volts, discharge it with a screwdriver. If the capacitor reads in the hundreds of volts, the safest way to discharge it is with a discharge tool, rather than a screwdriver.
There should be a small plus sign (+) on the side that is positive. Often, this will be on the side that is not shaded. ... Be sure you are operating on the correct side of the motherboard— the side opposite the capacitor itself. Reheat the soldering iron. Put fresh solder on the tip of the iron. Touch molten solder to the bent capacitor pin.
It makes everything easier, for example, it is possible to desolder 4700uF/16V capacitor using 25W soldering iron with flat tip. Never had motherboard malfunction after replacing capacitors.

One recommended condition for manual soldering is that the tip of the soldering iron should be <360 °C and the soldering contact time should be no longer than 3 seconds. For uncoated MKT capacitors with lead spacings ≤10 mm (B32560/B32561) the following mea-sures are recommended: pre-heating to not more than 110 °C in the preheater phase

Get a flux pen, some tweezers with fine points and angled ends, a fine point soldering iron tip and some good solder 0.5mm diameter. Apply flux pen to the pads. Put the component down on the board - the flux will hold it. Tin the iron (not too much) and, holding the component down, touch the iron on one end. Then solder the other end.
So this time I carefully rolled the soldering iron around which effectively forced the melted solder to stay in several different places for a few seconds. The other thing I did was buy a Weller tip activator and dip the hot soldering iron tip into that paste (also rolling it around to throroughly clean the whole tip). I tried tinning some wire ...
Using a soldering iron, remove the old capacitors. Then solder in the new ones. Replace the board and screw it into place. Replace all the cables that you removed. ... Also let the soldering iron (and solder) heat up properly and be patient. Bruno Otazu - Nov 30, 2018. Completely agree with Bruno. Flux and nice hot soldering iron.
1. Use a new 25W soldering iron, my old irons didn''t get hot enough and were just a pain. A 25W iron got hot enough to do the job w/o burning everything. 2. Buy the smallest solder wire you can find at radio shack, I tried to use .062 dia wire and I kept globbing it everywere. .022 Diameter 1.5oz wire worked GREAT! 3.
