I feel like I'm missing out
because there aren't as many components to
be soldered. |
| Mr. Fusamura | : |
But, it is rather difficult
to solder such a component with small lead
pitches by using a soldering iron because
a lead terminal may be bridged with the adjacent
one. Maybe it is too difficult for you, Hikaru. |
| Hikaru |
: |
Do you think so?
First, I should solder the lower parts. Then,
I bend the lead wires, insert them, and re-bend
them. Then, I put the soldering tip and feed
the solder. Pull the solder and then the soldering
iron, from the joint.
Um? This is a good job, isn't it? |
| Mr. Fusamura | : |
Hikaru, you are doing well.
You are maintaining a good rhythm which is
important for soldering too. By the way, is
the soldering iron difficult to use if you
hold the soldering iron in that way? |
| Hikaru |
: |
Why? |
| Mr. Fusamura | : |
There is no
problem unless the soldering iron is difficult
to use. I hold a soldering iron like a pencil
(Photo 2). Some people hold a soldering iron
with the whole grip. (Photo 3) Probably, children
or people with small hands can more easily
use a soldering iron by holding it with the
whole grip. I'm somewhat concerned about it
because you seem to follow what I do. |

| Hikaru |
: |
I can use the soldering iron
more easily in this way too. By the way, what
is this black component with three leads? |
Photo 4
|
| Mr. Fusamura | : |
This is called the "transistor".
(Photo 4) It can amplify an electric current
or voltage, or serve as a switch. |
| Hikaru |
: |
It seems to be a somewhat complicated
component. |
| Mr. Fusamura | : |
Transistors in the past were
easily affected by heat. They will break down
if the internal temperature exceeds 80ºC |
