| Mr.
Fusamura |
: |
Can you understand it? |
| Hikaru |
: |
It seems difficult. |
| Mr. Fusamura |
: |
Don't worry if you can't understand it right
now. You may study it if you get interested
in it.
Let's work on this today anyway. |
| Hikaru |
: |
Yes. |
| Mr. Fusamura |
: |
Wait a minute.
I'll bring the tools we need - nippers, long-nose
pliers, cutters, ...csolder and the iron holder. |
| Hikaru |
: |
You have everything in your
home! |
| Mr. Fusamura |
: |
I do have a lot. OK. We are
ready. |
| Hikaru |
: |
Well, which parts should I solder first? |
| Mr. Fusamura |
: |
You had better
start with the lower parts such as
jumper wires, resistors and diodes. If you
solder taller parts first, lower parts are
difficult to solder. |
| Hikaru |
: |
I see. There are many things to learn about
soldering. Well, I'll start with the jumper
wires. |
| Mr. Fusamura |
: |
As described
in the instruction manual, we should use surplus
parts of resistor and capacitor lead wires
that have been cut off after soldering as
jumper wires. Therefore, we should solder
the resistor first. |
| Hikaru |
: |
I see. |
| Mr. Fusamura |
: |
I'll try
first. Bend the lead wires of the resistor
with the long-nose pliers into the length
that can be fit into the holes in the board.
(Photo 1) These holes in the board are called
"through holes". Then, insert the
bended lead wires into the through holes.
(Photo 2) Since the resistor does not have
positive and negative polarities fixed, you
may insert them in any orientation. Then,
turn over the board and bend the lead wires
outward near the through holes. This can
prevent the component from coming off when
it is soldered. |
