Did you clean and lube your solder sucker? It makes a big difference even on a cheap one.

I use Edsyn Deluxe SOLDAPULLT with ceramic tip (very hard to find), use it for years and years and years, just have too keep it clean like redwire said. Stay away from the Chinese knockoff.

Re: What is a mechanical solder sucker?

Yes, it's a brand name and there's no difficulty finding sellers that I can see from here in the US.

Re: What is a mechanical solder sucker?

And I was looking at getting a good solder sucker, now is soldapullt a brand that belongs to edsyn? Or it's an actual word that any company can use because I see some soldapullt made by different companies. The edsyn seems hard to fine.

Re: What is a mechanical solder sucker?

I agree, clean and lube the sucker and get a good photo of the board with the problem. If you've lifted a pad that can be dealt with but a good picture is needed of it to advise properly.

foto time.

Re: What is a mechanical solder sucker?

Well I got the holes cleared enough to put the caps back in and I tried to solder them but there is one of the legs that solder doesn't flow in the hole when heat is applied. Maybe I lifted the pad and removed it? What does the pad look like on a motherboard capacitor? All the picture I see online seem to show a pad from a small PCB and it doesn't look like what I am seeing on the motherboard.

Re: What is a mechanical solder sucker?

The best I worked with, in a repair shop 500x a day, are the Edsyn soldapullt or the anti-static version. Haven't tried the chinese knock-offs of it.
Trick is to put a little Lubriplate (grease) on the o-ring and inside tube. That makes a huge difference.
Many solder suckers have crappy suction and poor technique can also make people give up.

I always add flux to my wick just before using it, along the bottom 2 inches

Re: What is a mechanical solder sucker?

personally i would be using a pump - i'v never got braid to work on something large like that.

A pump as in a solder sucker? I have one too but it seems like there is not enough solder to suck, unless my solder sucker is not that good.

Re: What is a mechanical solder sucker?

Practice and experience will teach you a lot.

Re: What is a mechanical solder sucker?

well the flux is o.k.
the mg braid is good, but probably not for this type of work.
the nexxtech junk is a mystery.

Re: What is a mechanical solder sucker?

Ok so I took a picture of everything I am using right now. I also bought a 3.2mm chisel tip today, it seemed to help but I still can't pick up all the solder that i need to pick up. I tried both wick's to no avail. I also noticed sometimes when I tin the tip, the solder that was added to the tip gets transferred to the board and I end up with excess solder, is there something i'm doing wrong?

I know the super wick says for lead free solder but I don't know what kind of solder was originally used on the board, the nextech one doesn't meantion lead free but wether I used one or the other, it doesn't make a difference.

Re: What is a mechanical solder sucker?

worth saying at this point, there are many fluxes for different jobs.
some dont like high temperatures,
some dont like lead-free solder,
some will eat your stuff like blood from an alien!

i really need to make a post soon about solders and fluxes for people.
the right solder and the right flux - both in it and seperate, make a whole world of difference.
specially with a decent iron like the 888D

Re: What is a mechanical solder sucker?

So is my tip no good anymore? Should I buy another one, or it's still good, I just need to re-tin and it should be ok?

if the tip is darkened and wont wet/adhere to the solder, it then becomes very hard to melt the solder and retin it again. another way u can also try instead of a wire wool is to use a tip refresher to burn away the darkened oxide layer and it also instantly retins the tip at the same time. this method seems easier for newbies. for wiping with a wire wool, u need to quickly retin the tip again or else it will become darkened again and u end up having to wipe it again and it becomes an endless loop.

however, be warned that those tip refreshers use a weak acid and is corrosive to pcbs. after dipping the tip in the refresher, make sure u wipe the tip on a wet sponge repeatedly to get rid of the acid and wash and rinse the sponge off and then wipe the tip on the freshly cleaned sponge again to remove all traces of the acid to avoid dmging boards.

you will never get stuff from a motherboard with 1.6

Re: What is a mechanical solder sucker?

The tip i am using came with the hakko and it's a 1.6mm chisel tip, is that too big? It's the T18-D16 1.6D.

In my experience, that one is a little too small to move enough heat to get good results with motherboards. I mainly use a 3.2mm chisel tip for that (T18-D32). Personal preference and technique do come into play with tip choice, though.

Re: What is a mechanical solder sucker?

Ensure it's good wick, i used to struggle with it until i bought some Chemtronics, it's already fluxed i believe.

Re: What is a mechanical solder sucker?

I bought a flux pen but do I apply the flux to the solder to be wicked up or to the wick itself? I tried both but they dont seem to work

if the wick does not suck, cut only a small part and hold it with a tweezer.

in some cases the tip from the iron its to small and it can`t heat up the cooper wick and it does NOT suck.

that`s why i use 3 irons . 0.2mm 1mm and one extra i don`t know the size its so big.
