I recently took this board out of my closet, its never been used and was purchased new 2 yrs ago. Then i had checked the board over and everything looked ok, even all the caps looked nice and flat. Anyway I went to finally get around to using it and 3 of the caps around the memory area are swollen, with one really swollen near the top.
My questions are the following. I purchased 5 new caps for the bad ones, the old ones are brown with the following: kzg 6.3v 2200uf (m)105c 3171 d1, all printed on the cylinder. The replacements i got were from ratshack and are the following: nte 6.3v 2200uf 85c +- 20% and grey in color, the part # is nev2200m6.3ef rohs. Can i use these replacments for the bad ones on this board? I think after reading and reading, everything is correct except the temp, but even that from what ive read is ok, since this is on a mb near the mem sockets and one coil? Also what is the % marking for on the new ones, is it for the tolerance or variation of temp since its on that side of the cylinder?
Finally, if i can use these in place of the old ones, i read the faq on soldering and i have a 45w pencil iron, and a 100w gun type. I remember back in the 486 era i swapped a cap out from a board where the cap became loose and broke off of a leg. So I just used the iron and slowly and in small increments heated and finally pushed the old one out, then just heated one pad then the other with the old solder in it and put the new cap in its place, and it was ok. From what ive read yeah this was totally wrong but it did work. What I'm asking is has anyone else done that successfully or is it best on this new board to go the full 9 yrds and remove the old including solder and use new solder, yes i'm a little rusty @ soldering? If so, any other addtl tips especially for soldering newbies for easily replacing a cap?
Thanks in advance.
