yes, i'm sure i will be linking many posts to this one

Do it.  It's needed.  Might be worth showing some bad 'uns as well (let the solder sit on the iron for a bit so it goes all dull and manky, then do the jumpers!)

[Exobex]

Sometimes I find that the solder just refuses to bridge the gap.  You know how solder is, it'll build up either side of a hairline crack in a PCB track without bridging, but accidentally touch the legs of an IC with the iron and it's wick time!

If the solder doesn't bridge the jumper on the first few tries, I reach for the wire.

I use a fiberglass pen to LIGHTLY clean the solder points, 18w soldering iron with a tiny tiny blob of solder......

ends up looking like  " ^ " or an inverted " Y " if I used a bit too much solder

NB:

note the LIGHT use of a fiberglass pen - angle-grinder not really needed to "clean or key" the area

18w not 35w soldering iron with a very small tip not a bloomin' great big screwdriver tip

tiny means a 1.5mm ball of solder not half the reel of solder


fiberglass pen is also used on the D0 point and also a tiny bit of flux helps here too for a good quick joint when I fit a mod-chip instead of flashing tsop

if in doubt and no multimeter close to hand have a lookey at it with a magnifying glass to see the points were joined ok

and yes for a bit of fun did a 1.2 with tiny kynar wire to bridge the points - jeez that was fiddly compared to a tiny dab of solder on the tsop points
last tsop I did was a green xbox 1.2 with mobo in situ and coz it was ST 007 evox flashed without needing pc/telnet (top 2 tsop points only btw)
well quick but think it don't hurt to remove mobo - far easier to work on than trying to reach into the xbrick

maybe not but not had to re-do any points after fitting back in case

just habit - found it "takes" ok so carried on with a gentle clean of the points

always cleaned the bottom points underneath when fitting messiah-x's to ver 1.0's to flash tsop - so just carried on with a gentle clean of these points on the tsop and when fitting a LPC mod and using alt D0 - clean that too with the pen I got lying around

if you are having trouble bridging the jumpers, i find it easier to get a piece of single strand wire and put a blob of solder on that, then hold that over the jumpers and heat it with the iron, u can then trim off the spare wire.

i found it harder to do it that way...
