Where can I replace capacitor?

greenmeansgo SG

Hi all,

I have a speaker set that is in good working order except for one capacitor blown. Anyone know where I can get a new capacitor solder on for me?

Check out Sim Lim Tower.

It'd be best to remove the cap first and let them have a look before you purchase; if you do not know anything about caps.

Thanks. Do you know about how much is the cost of the service?

I'm not very good at removing the caps from the board, I only know that I can solder on an equal or higher rated cap only.

Agar how much is the soldering iron and where is a good place to buy it?

soldering iron $20 + old sim lim

Seems like caps are a major source of problems.

I got a modem with caps blown, checked online and found it is a widespread issue. A few of my motherboards in the past too.

By old Sim Lim, do you mean Sim Lim Tower?

If got the old caps leaking juice, do I need to clean that off? And the solder serves a conductive and structural function, right?

I'm not going to use a soldering iron often so I might be cheapo and do this next to my stove with a hot screwdriver instead. Since the caps legs are so thin, hopefully just enough solder to hold the cap in place will do.

buy cheap 1s $10 n buy solderin leads

Thanks friend! DIY = fun

Btw are soldered caps fit for computers? Some of my old motherboards caps are right next to the CPU heatsink, they started leaking under the heat. (Asus some more!)

sometime high static current can damage the board

sometime high static current can damage the board

Meaning the soldering of caps can cause static current?

Taking usual precaution of grounding myself and putting the board on a static bag will be enough?

Buy a soldering iron, a solder sucker (it's really called a sucker) and capacitator from Simlim tower.

The iron would be $15 odd. Sucker $3 odd.. and lead. capactitator = few cents to <$5 (it's actually less than $3 normally)

Removing the cap:

If it's soldered on to the board - put your solder iron on the bottom side of the board where you should see silver/grey solders that are attached to the capacitator. Heat it up with the iron till the lead melts. Use the sucker to suck the melted leads and continue doing so for till the capacitator drops out or if you can pull it out.

Replace the cap exactly the same as the one that is spoilt, holding one hand on the lead and 1 on the iron solder the cap.

The capacitor plague (also known as bad capacitors) was a problem with a large number of premature failures of aluminium electrolytic capacitors with non solid or liquid electrolyte of certain brands especially from Taiwan manufacturers. The first flawed capacitors were seen in 1999, but most of the affected capacitors failed in the early to mid 2000s.
