The story behind the white slippers at Ginzinger

In the course of a personal meeting at Ginzinger, they usually catch the eye right away and attract attention. They are practical, comfortable and have virtually become the employees' trademark. Lately, they have even become quite trendy. We are talking about slippers at Ginzinger electronic systems.

Rumor has it that Ginzinger electronic systems was the catalyst for the trend that has been hitting the streets for several summer seasons:
From flashy neon colors to glittery gold, whether as toe separators or "normal" sandals:


The health slippers of a well-known German brand that begins with "B" are celebrating a brilliant comeback.

But all joking aside, there are of course no visual reasons why new employees at Ginzinger are given a pair of white slippers along with their work documents, Ginzinger shirt and access tag. It's about something much more important: protecting the customer products that are developed and produced in-house. You may now ask: How do you protect highly complex electronics with the help of sandals?

###IMAGE2## Let's "get to the bottom" of this. Looking closely at our slippers, we notice a yellow button. Printed on it is the symbol for "ESD": Electrostatic discharge. So it's all about electrostatic discharge. Yes, exactly - our slippers - or more precisely, the soles of our shoes - have a special ESD feature that protects against spontaneous static discharges.

Everyone is familiar with this: when - usually in the cold season - you touch the handle of the car door, for example, and get a small electric shock. Or you crackle from top to bottom when putting on your cozy synthetic fiber winter sweater and then try in vain to do your hair without your electrically charged hair standing on end. Then you witnessed, or rather became part of, a genuine electrostatic discharge.   

And that is not without its problems. Up to 35,000 volts can be generated at short notice. This depends on various criteria, such as material or air humidity.

###IMAGE4##What is harmless to humans due to the low energy is highly critical for electronic semiconductor components. The sensibility of an ESD pulse is at 3,000 volts, which is where we first perceive the electrostatic discharge in the first place. However, components can already be damaged from a voltage range of 20V to 500V without this being noticed. This is a big problem, because components that have been damaged by ESD are very difficult to detect.

To prevent this in advance, it is important to ensure a controlled "soft" discharge in production that is harmless to components. This is achieved by careful personnel and workplace equipment.

To this end, our entire production area is ESD-protected. From the dissipative floor system, to special work tables and chairs, to tools and component boxes, everything is ESD-compatible. Constant air humidification also ensures consistent climatic conditions in production.


In addition to the correct equipment of the work area, the comprehensive ESD measures also include the right personal equipment at Ginzinger electronic systems. This consists of ESD shirts, ESD coats and a wrist grounding strap that must be worn when handling electronic components. And of course our conductive ESD slippers. This combination of workplace and personal equipment offers the greatest possible protection against ESD when handling electronics.


The only question that remains is: Why white shoes of all things and not black or blue? From a purely psychological point of view, we associate the color white with purity, order and knowledge. All things that undoubtedly play an important role at Ginzinger electronic systems. But whether this was the decisive factor in the choice of shoe color remains to be seen.
