STORY 8: Hikaru Meets Mr. Yokoo again

1|2|3|4

Hikaru joined a manufacturer.

Today is the first day of the new employee training in the company.

Hikaru

I'm a working member of society starting today. I feel the pressure.
I'm the only new employee here? I wonder if I will have an opportunity to have a party with new women employees?

Mr.Yokoo

Good morning. Oh, you are the person I met before.

Hikaru

Oh, you are Mr. Yokoo, aren't you?

Mr.Yokoo

You are a new employee of our company. Yes, it's a common story. Anyway, It's nice to meet you.
Well, then, I have not asked your name. Please introduce yourself.

Hikaru

I'm Hikaru Jyo, twenty-two years old. My hobby is listening to music. I'm interested in electronic handicrafts. I'm pleased to meet you.

Mr.Yokoo

Maybe I can talk with you about "Electronic handicrafts" for fun. Ha-ha-ha-ha-ha (Laughing) I'm Yokoo from the Manufacturing Section. So what topic did we discuss that day? I'm so forgetful these days.

Hikaru

We talked about the history of soldering. We interrupted our talk when I asked why the soldering technology has been used until now with little change.

Mr.Yokoo

I remember that. You have a good memory, Hiroshi.

Hikaru

Excuse me. My name is Hikaru ·····.

Mr.Yokoo

Oh, I'm sorry. I can hardly remember any names these days. From a viewpoint of soldering technology, the technology has been advanced daily. For the advance in soldering irons, soldering irons were heated with coal in the past and then modified to use electric heaters. Some of them can be temperature-controlled in order to maintain the soldering tip temperature accurately. For soldering methods, the soldering method using soldering irons has been considerably reduced in number these days. I'll talk about this later. There are a variety of soldering methods, including ultrasonic and laser soldering, as well as reflow and flow soldering. In other words, the soldering tools and soldering methods have been advanced beyond our imagination from those in the past. But, there are little changes in the materials.

Hikaru

I think that's true.
