Re: What is a mechanical solder sucker?
Well I got all the capacitors in, not sure if I should power up the board, i'm not confident in skills. Do you guys think it looks ok or some things might be shorted once power is applied?...

Re: What is a mechanical solder sucker?
If anyone could help me choose some 680uf 4v capacitors below:

I don't know exactly...Leave a comment:

Re: What is a mechanical solder sucker?
Actually I guess it's a poly since it doesn't have the vents on top. So my question is can I replace this capacitor with a sleeveless capacitor? It basically looks like an all metal cap but it has the same values.Last edited by johnnyh55; 11-04-2015, 08:47 AM.Leave a comment:

from what i can res 680uf 4volts 105c TMJ and on the top its written 67 c7Leave a comment:

Ok, can you elaborate on select carefully? I was only going by 680uf and 4volts....Leave a comment:

Re: What is a mechanical solder sucker?
Well according to post #4 in this thread, it's perfectly fine to replace the aluminum electrolytic caps with solid polymer ones:

Is that true?Re: What is a mechanical solder sucker?

Re: What is a mechanical solder sucker?
Sorry I meant polymer.
Actually it's the other way around. Right now I have aluminum electrolytic and I'd like to replace them with aluminum polymer capacitors, would that be ok? I can't find 680uf 4v caps in aluminum electrolytic only in aluminum polymer. I can find 680uf in higher voltage like the ones I have now but the dimensions are usually too big and I don't think they would fit....Last edited by johnnyh55; 11-03-2015, 11:13 AM.Leave a comment:

Re: What is a mechanical solder sucker?
Now that I think of it I think these caps will be in the way of the heatsink so I will order some new ones 8mmx8mm. If I replace polyester caps with aluminum caps would that be ok? The only ones that would work from digikey are aluminum caps 680uf 6.3v and they are 8x8mm.Leave a comment:

Re: What is a mechanical solder sucker?
Well thanks for all your help, I figured out a technique where I apply flux to the solder on top of the vias to be clean and then I align my safety pin and I apply heat with the iron. The the pin goes through almost like butter and I then wiggle it and pull it out and it clears the hole.
Now some of my caps are the right capacitance but too big physically for the ones they are replacing(1800uf 35v instead of 6.3v) or they hit each other side by side, if they don't touch the board does it matter if they don't interfere with other...Last edited by johnnyh55; 11-02-2015, 05:15 PM.Leave a comment:

Re: What is a mechanical solder sucker?
Do you think it will bond better or probably not?...Leave a comment:

Re: What is a mechanical solder sucker?
Actually the ones I got are silver so I assume they are steel? Maybe the solder is not sticking to it but the pin gets stuck inside the vias?...Leave a comment:

Re: What is a mechanical solder sucker?
Ya I probably do. I've done dozens of capacitors on single sided pcb boards with an el cheapo 25w iron but I didn't think the motherboard would be this hard with a good iron. I tried using a safety pin to clear the vias but solder seem to sitck to the pin, so it's not working as I was hoping for. Maybe the ones I got from the dollar store aren't made from stainless steel....Leave a comment:

Re: What is a mechanical solder sucker?
I was thinking that my 1.2mm solder might be too thick? If I purchase 0.8mm solder, should I use lead free solder or buy leaded solder? I know lead free is harder to work with but is there less chance of having a cold solder joint if the board uses lead free solder?Leave a comment:

Re: What is a mechanical solder sucker?
Ok, thanks for the help. Here is a picture of the capacitors I am trying to solder in. I squared the area of the one that I think has a lifted pad....Leave a comment:

Ok. I was told never to use petroleum based lubricants on rubber O-rings as they will dry and crack overtime. I'll get some silicone grease and try that....Leave a comment:

What kind of lube do you use? Does it need to be something real specific?...Leave a comment:

Re: What is a mechanical solder sucker?
Ok so I was confused, the store what listing the supplier and I though it was the brand of the product. So the one I am looking at is actually a Edsyn soldapullt DS017-P maybe ill pick it up tonight and see if it works better than mine.Leave a comment:

Re: What is a mechanical solder sucker?
No actually I didn't clean and lube it, just removed the excess solder by pressing on the button and the plunger sticks out ejecting the solder. I didn't know I had to lube either....Leave a comment:

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.Leave a comment:
