[Bridged pins] How to remove? [Panasonic chip]

[Pacotera]

I was trying so hard to get rid of those nasty out of sync errors using different capacitators (47pf did the trick but after 1 min or so they came back) that i took the pad 4 off... so i traced to the panasonic chip and solded there...

Aparently i got the wrong leg and when i tried to take the weld it bridged with the legs next to it... so i got 4 legs together...

I tried using the sucker and the wicker and was unable to get it all.. its pretty micro between those legs...

Whats the best way to proceed?

Maybe a heat gun or something?

Thanks in advanced

buy a desoldering braid and use that to pull off the solder.

he stated in his original post that he tried it.

well, i use desolder braid all the time, and have used it for bridged pins, if you know how to use it properly (not a dig at you) it should be no problem sorting out bridged pins, there are exceptions though, where it can be a pain in the arse (fixed a laptop earlier this week, should of been a two minute solder job, turned into a 2 hour nightmare, good result in the end though :D )

my favourite method with desolder braid :-

rub a tiny amount of flux across the pins, (a tiny amount , again just dampen a cotton bud with flux paste and wipe across, then go over with the dry end) this will help draw any excess solder away from the other pins either side.

then with clean small gauge desolder braid , wipe this over with a small amount of flux paste.

make sure your tip is clean and free from solder.

lay just the width of the braid across the bridged pins.

then touch the desolder braid with the tip or the iron ontop, and apply a little pressure, this should remove the excess solder. ;)


and for future reference for people heres a couple of photos of a repair i did for a customer, with also a `map` of the contacts to the panasonic chip for easy tracing.
