[sdiy] Soldering Transistors

[Martin Czech]

:::from what I have found, its *very* difficult to overheat modern trannies. I
:::would say that you have an ESD prob with your iron or are wiring them wrong.
:::Wiring them wrong happens with a lot of ratshack stuff, because when you get
:::that trannie assortment not *all* of them seem to pin out the way they look
:::on the back of the blisterpack.
:::
:::I test them first for CBE and what pin goes to what.

I even forget what pin is which on LEDs, so I measure them every time.

SSounds like an unsufficient or too cold iron. Get a regulated iron
and turn it pretty hot. So you only need to solder for 1 second or so.
The transistor will not get that hot. A good iron is simply a good investion
for life. 

Of course, it could be bad solder as well, this cheap stuff
they sell in radio shops has much to much lead, the results are awfull.
The solder dot must be shiny.

I never use heat clips, and I can't remember to have fried a tranny
(with the iron!) in my life.
