I need some recommendation about using hot glue for securing
electronic components on PCB (motherboard).
What type of hot glue and "gun" for it is best?

The Only Way Is Up

iv'e used hot glue on transformers after removing
the internal fuse that blows to force peaple
to buy new transformers.
and i use candle wax on some pcb's.

NOT recommanded!

We get this problem with hot glue breaking solder connections a year
to couple years after the manufacture.

If this is one off, position each flat pack SMD that has more than 2
leads component and tack one corner pin and another to secure it and
finish rest of soldering on that component.

In production used very tiny dots of special glue and component is
placed on still liquid dots then cured hard to secure small and medium
sized components for wave or IR soldering then rest of big parts are
individually installed and soldered seperately like BGA, 100 pin SMD
etc.

That special glue hardens like epoxy but moderate force breaks
component loose from this glue's grip during unsoldering job.

Cheers,

What about using it to glue battery holder, away from solder
connections (not very far, though, its a coin type, lithium battery)?

I reckon that's fine, this guy is talking about SMDs etc with much
finer tolerances. Don't make a mistake though, it's messy melting it
off again.

I regularly use it to add strength to damaged power connectors etc,
where the only support was the solder on the pcb, stupid designs...

I do that as well. After soldering leads or connectors, seal them with
a medium temp hot glue to reinforce the fix and avoid stress breaks.
I use hot glue in jacks and coax connectors as well to avoid stress
and pull breaks and avoid shorts or grounding.
(After soldering the leads in my mini stereo jacks I give it a squirt
of hot glue then screw on the plastic boot. They last much longer that
way.)

I think hot glue is great. I have used it on pcbs on my motorcycle. It keeps "large parts" from
vibrating and breaking solder joints. I don't think the gun or glue is important. You can get small
or large guns I have both. The glue type depends on the heat in the area, low temp will reflow in a
high heat area.
As for removel, alcohol (isopropyl) "breaks down" the glue, and you can pick it off the parts.

Actually I find a hair dryer will warm it enough to soften and allow
it to be peeled off. Crappy stuff for electronics though since it
loses strength as the gear warms up. Devcon plastic welder is my
favorite for mechanical repairs to broken plastics. Much stroger than
epoxy. Pretty strong on metals, too.

I find myself needing some specialized extender boards to repair some HP &
Tektronix instruments.

Is there a known source for these other than the manufacturer?

If I wanted to make my own extender boards, what's the best source for a
large variety of edge connectors?

ebay, garage sales, flewmarkets of the radio amateur league...

Depending on age:
Major sellers like Digikey, RS comp..
Scrap yards...
Junk boxes of electronics companies..
