Repairing this new stuff with no ..

[Ken G.]

Service manuals & a bit of equipment . This seems almost impossible
these days . 20 year ago & on back you could repair this stuff pretty
well with just a multimeter and alot of experience .

The older electronics are fading away faster due to lack of parts and
cost of repairs . Have you seen inside a 20 year old tv set these days !
you HAVE to take it outside & spend time cleaning it out before you can
even see the parts . My brother runs a repair shop with no equipment
or manuals ... i wonder how long that will last ? ... cant change
surface mount chips with a weller soldering 2 speed gun

I'd have to disagree with this statement. If this is a quality soldering gun
that can run at high temp, then you should have no probs changing stuff in
SOIC package. Well, obviously it's going to be painful... I am so glad I got
Solomon 48W soldering station two days ago to replace my aging soldering
iron....

You are not supposed to solder electronics with a soldering gun . I have

replaced a fair number of surface mount chips with an Antex low watt
minature soldering iron .

It can be done, I drag out the big Weller gun for those big heavy pins,
ground plains, etc, sometimes I get lazy and use it on other parts too, as
long as you're quick it works fine.

What you need is a hot air rework station, all the right nozzles and
forks, a huntron, a scope, good meters, including an esr meter.
Then, you need real experience, real knowledge of the theory of
operation.
Sure, you can stumble along, removing all that smd stuff w/ some
soldering irons, but to do it right, you need the right stuff.
The hot air station will allow youto quickly remove all the various quad
flat IC packages, and the soic packs also. (without damage to the board
or the IC)
The huntron will allow you to identify bad parts with no manual or
desoldering needed
The experience and knowledge is what you really need though. Swapping
parts is no substitute for real troubleshooting.
Repairing electronics is not what it used to be. Adapt, or go the way
of the dinosaurs

Nope, a standard iron, a 20mhz scope and one multimeter will diagnose
99% of problems

Agreed

You can do it right with a standard iron. I used to work at a place
that had all the goodies, but I never used them.

Couldn't agree more. I have managed to do repairs on SMD gear with
only a tube of flux and a gas iron. When you 18hours drive from the
nearest town then you have to manage. You just have to make damn sure
you know what the problem is first time.

Where the heck do you live, anyway ?

I live in Australia, but my work takes to me to places that are many
hours travel. When I say 18 hours, I am talking about some real rugged
country that may take only 8 hours if it were on a sealed road.

Man, they must really want that stuff fixed!

Thay pay top $ to get you there, they don't want you turning around
and going back without it fixed! 99% of the time it is just a swap
out, but sometimes you just cant be prepared for everything! The other
1% of the time is another problem developing when you are headed out
to the site, not the origonal call out.

The episode I had in mind was the replacement of a MAX232 in a SOIC
package. Paste flux (always carry a tube), a wella portasol and some
22g solder. I couldn't believe my luck when I found a tube of MAX232's
in the truck! Normally in that situation I would just hack a DIP
package into place to get me out of trouble. Had the exect same
incedent about 3 months ago, but without a spare. Fortunately I was
only 2 hours from the city that time
