As someone who worked in manufacturing circuit boards, after you replace the caps, glue them back down with a hot glue gun. The glue does wonders to keep them from breaking from vibration and stress.
If it's a hard brittle substance, try using a hammer and punch to dislodge the capacitor. If that doesn't work, try a bigger hammer! Do you need to keep the cap intact? If not, I would cut the leads, desolder them, and get pliers and gently roll the cap side to side to remove it.
The knife needs a bit of strain to remove after attempt. If it is epoxy, heat might work. Try going outside (or at least open the window wide), and use an old soldering iron. Remember that you don't want to save the cap, but you want to keep the board in good shape. Cutting the leads before attacking the glue will be a good idea.
Otherwise, try a bit of acetone on the glue and see if it softens any. (Acetone + perfume = nail polish remover.) If it's a hard brittle substance, try using a hammer and punch to dislodge the capacitor. If that doesn't work, try a bigger hammer! Do you need to keep the cap intact?
If it were superglue, you could get some remover (yea, they make a chemical that will soften superglue!), but if it's epoxy you've no such luck (the only chemical that would work is pretty carcinogenic and thus not readily available).

Powering on issues from cold is a capacitor ESR symptom. As the capacitors warm ESR is lowered, so a marginal capacitor can become operational when the TV is warm. If marginal, warming the caps gently with a hot air gun/hair dryer aimed at the caps can prove it, the fault will appear to go away if so and allow you to power cycle.

We go step by step on how to remove and install your new capacitor!
The jacket is glued down. Can you slit the plastic and remove the capacitor, leaving the jacket where it is? Otherwise, try a bit of acetone on the glue and …
Now you can glue the blister back down again and wait for it to dry; I recommend using a PVA Wood Glue as it dries clear and can be applied neatly using a (different) Q-Tip; There are other options – so long as you DO NOT USE SUPERGLUE as this will strip the colours and ink from the front of the card….not to mention it dries leaving a white bird-shit type …
For best results, avoid using hot glue on thermally sensitive components or power devices that produce heat. As the article says, this isn''t just because heat-producing components could re-melt the glue. Many components--notably resistors and power transistors--need to dissipate heat to function properly. Their surface area and mount points are ...

I can''t offhand think of a variable capacitor type that the spindle isn''t ground. The varicap option is one or two diodes, if you apply a reverse bias the depletion region gets bigger - that''s the same as the distance parameter between the plates of a capacitor, the higher the reverse bias - the lower the capacitance. I referred to this in an ...
On average, the cost of capacitor replacement typically ranges from $100 to $300, including both the cost of the capacitor itself and the labor for installation. However, this is a general estimate, and actual costs may vary based on individual circumstances.
It looks like the capacitors are glued quite firmly to the board in an upright position. What is the best way to remove the glue? Also looking for recommendations for the best caps for this purpose. I usually unsolder the leads and try to "roll" the cap until the glue breaks.
Hot glue never holds, I''ve even tried cleaning the spots with acetone. 😱 😉 If you don''t have the metal clamp rings, make some! If I need to strap caps flat to a chassis I just cut a strip, bend it around the cap and bend a tab on the end (after cutting to proper length), drill for the screw and tighten it down.
So we suspect that one of the fields that Glue initially inferred as INT now has to be changed to BIGINT. For some reason, the crawler didn''t do that automatically, so we need to fix it. The obvious attempt was to edit the table schema from struct<...,field:int,...> to struct<...,field:bigint,...>, but doing so results in:
Definitely was glue and not a leaking capacitor since there was no metal attack under the gunk. Reply reply More replies. deceptivelyelevated • That''s glue to hold the capacitor still, it prevents the solder joint from breaking. ...
Unsolder the leasd and roll it off of the glue. You can also use a razor blade to carefully cut the glue by slipping the razor under the cap.
My solution: cut around it with a knife, try to scrape some off the PCB as best as I can, then replace the caps and forget about it. Re: How best to remove glued down capacitors without damaging the board? The heat and the IPA is probably more effective if the glue isn''t …

capacitor glue. Post by Omicron » Sat Feb 18, 2012 8:56 pm. Hi everyone, So this is a stupid question. A friend messed up the input jack on his Peavey solid-state amp, so I''m going to replace it. It''s loaded up with a dozen electrolytic caps, so I figure I''ll replace those while I''m in there as well - they''re probably 10 years old at this point. A bunch of them are glued, …
Hi all, Does anyone know the type of glue PCB manufactures use to glue big components to the PC board? It is the white stuff you see on capacitors of SMPS''s to prevent them from breaking off the board due to vibration. I am looking for glue that does not contain any silicone. A brand name would be helpful. The IPC approved stuff would be best ...
Hot melt glue the new capacitor to the top of the board, the jumpers should remain twisted. Tip1: If a capacitor has long enough leads exposed on the front side of the board, you can cut the capacitor off leaving the old leads and solder the new capacitor to the old leads. This method is even faster. See the last picture for an example.
Create the second capacitor plate on the reverse side of position 2. This time, the straightened end of the paperclip must stick out at the top. Fold the first plate back over it from right to left and glue securely in place. …
If you''re not trying to preserve the capacitor, I''d go with a heat gun. The heat required to soften the glue should be much less than the heat that would dissolve solder or separate traces from circuit boards. You might have problems with nearby components so you''ll have to judge collateral damage based on how crowded the card is.

I find it very difficult to remove the solder between the lead and the pad where the lead is bent at a 90 degree angle. Then when I go to wiggle on the cap gently to remove the cap, the glue that hold it down forces me to wiggle a little harder and the added resistance of the glue make it hard to tell if there is still some solder under the lead.
You don''t even have to scuff up the surfaces to be glued, it will hold nonetheless. It is solvent based (toluene, I think), so there could be some issues with it reacting with the board and it will be a bitch to remove if you ever have to. You can always lay the cap flat, drill holes on either side, and run a nylon tie around it ...
I try to take a very sharp utility knife or similar tool that is thin enough to slide under the capacitor (I use an Olfa knife like those used in the window tint industry). I usually start with a solder-sucker on the large filter caps first, then follow-up with some good solder wick and rosin to ensure all solder has been removed ...

The purpose of the glue is to anchor the capacitor to the PCB so that it does not break off with vibration/drops. It looks like the application is not ideal in that case since there is very much glue on the capacitor and little contact between the glue and the PCB.
After you get it up off the glue then desolder. Whatever you do, obviously, you must de-solder all the joints first. Then you can chip, pry, pull, or tap it off.

The guy using the hot glue doesn''t need to be doing it either. However hot glue and be cracked off and removed cleanly, especially if it''s cooled. (Or you can heat it and melt it off.) Silicone is almost impossible to entirely remove cleanly. I clean plenty of boards that have both. Then I repair them. Neither is necessary after the board has ...
That''s perfectly normal, it''s a silicone glue used to keep the capacitors in place. Since they are not always sitting flush with a the board they want to make sure if the box is dropped or something that the capacitor won''t shift. As for the smell, perfectly normal.

Cyanoacrylate glues set fast (super glue, elephant glue), risk marring surfaces in some applications and will debond with time on some surfaces. Latex and contact glues are low modulus and can be useful. Solvents tend to be used which may have adverse effects. Numerous others exist, but I''ve found silicone rubber to be the best overall.
