Good morning. |
| Mr.Yokoo |
: |
Good morning, Hikaru. Have you become accustomed to the
company? |
| Hikaru |
: |
Yes, I've become fairly accustomed to it. |
| Mr.Yokoo |
: |
I'm so glad to hear that.
By the way, I'll talk about various soldering
methods today. |
| Hikaru |
: |
Soldering methods called "Reflow" and "Flow"
that you mentioned before? |
| Mr.Yokoo |
: |
Yes. You have a good memory.
The number of electronic components used for
P.W.B.s in electric products is very large.
If these components are soldered one at a
time, it takes a lot of time and the soldering
cost is staggeringly high. Furthermore, labor
of soldering workers who handle so many components
is very large. |
| Hikaru |
: |
These seems somewhat interesting. |
| Mr.Yokoo |
: |
Making a single product may be interesting, but in the
case of mass production, you can't say that. |
| Hikaru |
: |
Yes, you're right. |
| Mr.Yokoo |
: |
Today, I'll explain how to solder a large quantity of
electronic components simultaneously. |
| Hikaru |
: |
It seems TV shopping or something like that. |
| Mr.Yokoo |
: |
That's crazy! |
| Hikaru |
: |
I'm sorry. |
| Mr.Yokoo |
: |
You really say a bit too much.
Soldering methods are generally classified
into three types: "Iron soldering",
"Dip soldering" and "Reflow
soldering". You know about "Iron
soldering", don't you? |
| Hikaru |
: |
Yes, of course. |
| Mr.Yokoo |
: |
The "Dip soldering method" is the method of
dipping a target part into melted solder.
The target part is directly heated with melted
solder. It can be illustrated like this: |
