how to fill xenon holes

[banjaxt]

title says it all really
i just cant get the solder to adhere to the holes (the row not j2d2)
im using no clean flux and a 15w iron

I'm assuming you are trying to install a pin header? If so, put the pin header in place and apply some flux then tin your iron with solder, touch each pin and the solder should run forming a clean connection.

I had a slight problem clearing the holes prior to installing the pin headers neither desoldering braid or a solder sucker seemed to clear enough solder. I then purchased a pin chuck and 0.8m drill bit and drilled by hand (carefully) I ended up with perfect holes and some solder left on the board(already tinned). Insert the pin headers, turn the board over and follow the tut "Why and how to solder" It worked like a charm.:smile:

To clarify,that should have read 0.8mm as drill size

Your iron has to be spotless or 'wet' with solder for proper flow into the holes.

I would argue that a 15W iron won't get anywhere near hot enough for lead-free application, not without causing damage along the way.

1. Clean the tip-it needs to be shiny.
2. Lightly flux the point you want to add solder to.
3. Place the soldering iron tip GENTLY on the point and feed about 1cm of solder into the point where the tip and hole meet. It should melt onto the tip of the iron.
4. Give it up to 10 seconds and you should see the solder melt into the point you have the iron on. If this doesn't happen, either your solder is no good (get some good ol fashioned leaded solder) or your iron isn't hot enough.

sorry i forgot to state in first post

i ment jtag holes, not nand holes. i mastered them last nite

thanks for thr idea of a 0.8 mm hole

I use a 30w iron for jtagging and 18w for drive pcb work

:facepalm:i got a 40w and near bust the board:facepalm:

15w only now but it works perfect

im talking bout j1f1 with the 6 empty holes

edit: i got the lead free solder stated in the 'best buy' topic.
thanks for info Martin C

Thats what Im talking about too. I also use the 30w with qsb's too. I found I couldnt get it hot enough (thicker pcb etc)
thats the only time I use a 30w though. Everything else (repair cuts on drive pcb etc) I use a 18w antek from maplin
