If you have some indium base solder or old leaded solder, reflow it
with that, then suck it out..
Also, I've used my hot air wand to clear the holes.

Carefully drill the solder out with a PCB drill slightly smaller than
the hole.


you must be careful to not remove the vias conductor when doing so.

***Easier said than done!

I have a tip I made for my Hot air wand that has a hypodermic needle on
it. I heat it up and hit the air switch and push it through the hole.

Jamie..

***Many years ago I made an SMD harvesting machine out of a portable LPG
heater and an old fridge compressor.

***The copper pipe was coiled and stuffed behind the guard on the
heater, right in front of the burners. A carburetor jet was peened into
the end of the copper pipe to produce a fierce jet of very hot air.

***A cardboard box on its side opposite the nozzle caught most of the
low flying SMDs, but I had to abandon it because it was just too hot
sitting so close to the heater.

When smt first started coming out, many of them were reusable and I had
and old converted reflow toaster oven. Any boards I was trying to
salvage smt parts on, I would switch on only the bottom heater to high
and stick the board in there with a catch tray. Just keep tapping on
the board top side with a metal wand so not to burn my fingers. This
would knock off the components into the tray below and I could sort out
the ones I wanted to keep.

I harvest lots of smt parts doing that but after some time when money
wasn't so tight, I then started to buy more new parts and found that
easier. I still have a converted reflow oven I use when I do hand
batches of small items.

I fully agree that adding leaded solder (and using a touch of liquid flux)
will make removal much easier.

I often carefully use a round toothpick during the heat application to clear
a blocked hole when I don't feel like setting up the desoldering station.

I consider the RoHS regulations pointless for repairs, as repairs aren't
manufacturing. If a tiny amount of lead would ever end up being an issue
during recycling, then it's the recycler's problem (to me, same as some food
left in a jar or the label on a recycled container).

If the disposal of the same tiny amount of lead would be an environmental
problem, then the waste company should be sending the item to a recycler
instead of dumping it in a pit.

Microsloth removed prefixing quoted messages with "> " in Windoze Live
Mail 15 last year. You can install earlier versions (WLM 2009, or WLM
2011) and you'll have proper quoting. This explains the situation:
<http://www.w7forums.com/windows-live-mail-11-reply-t10514.html>
with some additional notes on quoting in Outlook Express.

I would strongly recommend finding an alternative newsreader as your
creative formatting is difficult to read, and makes little sense as
you should be marking the quotes, not your added comments. I
recommend Forte Agent 7 which does cost $29, but in my never humble
opinion is worth it. 30 day demo to try it.

A cousin of mine lost her first child to lead *paint* poisoning in the 1960s
(partly due to improper medical attention), but that infant would not have
been injesting circuit board or plumbing parts.

Anti-lead regulations are just one more BOHICA, by my estimation.

The paint manufacturers came to the rescue with latex paint, which contained
mercury in the early years.. maybe some of it still does.

###While I remain against RoHS-Pb-free, I agree with the ban on lead in
paint. The removal of lead from petrol was also a pretty good idea - annual
petrochem procurement of lead for TEL anti-detonation additive was in the
hundreds of thousands of tons! - This ended up floating about in the
atmosphere for us to breath along with all the other exhaust particulates.
It also precipitated with rain onto agriculture and contaminated livestock.

The Brussels (braindead) suits just didn't understand the information put in
front of them.
