Ron Hudson Stated:
Another problem with most modern stuff is that it is
surface mount tiny "you can't work on it without
special tools" not meant for repair, only for
replacement.
This is not really a problem with surface mount. I
thought this would be impossible too - then I built,
as my first SMT project, a Nixie tube watch - with
"over 45" eyeballs that never worked perfectly.

I invested in only:
1. A GOOD temperature controlled iron ($50) from eBay
2. Good (but not great) tweezers ($5.00)
3. $5.00 set of eye loupes
4. $110.00 - a hot air rework station from eBay (I
didn't really need this)
5. Some flux "markers" and some really thin solder
from Digi-Key - around $20
Nice things about surface mount are that the parts are
really cheap, you can get a lot more stuff on a board
(board cost), and the parts can be fairly easily
recycled (especially with the rework station).
The real problem as I see it is the proliferation of
parts. The Digi-Key catalog is like, 10 times the size
it was in the 70/80's. Parts come and go very quickly
now. And with ASICs, you are at the mercy of the
manufacturer.
I am concerned that all the TTL in the surplus market
now is all that there is-I can't beleive that anyone
is making any more. Wire-wrap sockets and quality
punched boards are getting very expensive.
