Is this a leaking cap?
This is a photo from inside my Escom A4000T. What is that red stuff?
Is it the cap leaking? It looks like some sort of resin. http://www.hd-zone.com/leak.jpg |
It probably is a resin of some sort. Board manufacturers sometimes use a resin or adhesive sometimes to hold the components in place just prior to them being soldered

Thanks! |
Is it hard or soft ?

Definitely not electrolyte. It's probably just glue.

I agree with the others, looks nothing like cap leakage. :)

Jam Sarnie whilst working on your 'miggy?

On boards that use dual sides, most resistors and smaller caps are placed on the board using a glue, so that when the cards go through reflow ovens or reflow solder wave equipment nothing falls off.
I've not seen an electrolytic been glued before but there's no reason why it cannot be, this is 100% glue and not leakage in any way. http://img.alibaba.com/img/imagerepo...-web1_7950.jpg http://www.electronics-trading.com/Image/cartridge.jpg You will most likely find two or four dots somewhere on the board from when the adhesive was applied in the first place, one of the companies that I worked for used to use a Universal GSM only for this purpose and only ever on a few boards. http://i.ytimg.com/vi/gjsLktISVAE/0.jpg |
Glue for SMD part - each SMD is glued to PCB before soldering - without glue it simply fall from PCB (valid for wave soldering - when IR and similar methods are used for soldering glue in theory is not needed - solder past should be enough but anyway glue is used sometimes, also glue is required for two side component populated boards for bigger SMD, small ones are stay due of solder own surface tension)

Whooops, could'nt see whole of picture, :(.
I would agree with others, now I can actually see the cap on the right side of picture, :). |

Good news :) |

Thats the cap I was originally looking at, thought everyone was going nuts, cause I could'nt see the red stuff, lol. |
looks like poor camera sensor (debayer fail with low light?)

I had to shine a flash light on the board to get light and try to take the picture at the same time. |
The capacitor is leaking (see the grey colour on the pads). The red thing is SMD glue.
Swap it. |

IMO cap is ok - picture such quality like this can be confusing
