Electrostatic Discharge (ESD)

Technically speaking, Electrostatic Discharge (ESD) is an electrical discharge that occurs when two charged objects with different voltages are brought close to or touched. An example of static electricity that everyone once a student may have tried is using a pen with a plastic cover to rub it hard against clothes or clothes (usually the guy's friend sitting next to) to suck up debris. or even stick to the pen.

Of course, in the game the students mentioned above do not have an electrical discharge because the charge is quite small and the pieces of paper nor the pen do not conduct electricity well. In fact, electrostatic discharge can make us feel like an electric shock in the blink of an eye and even damage electronic devices.

If you have not seen ESD as an issue of concern in the electronics sector, it is not uncommon. Honestly, I used to think that ESD was not that big of a deal. Of course not because I did not know what ESD was at the time (like, "electrically ignorant" and still "deaf and not afraid of guns") but even now trying to remember my school days and I did not find anything to show that I was exposed to ESD, except for a pen and scrap paper when I went to work in Vietnam.

Then I moved from work and continued to design the IC. And then I finally get to "taste" ESD, if not every day, quite often. And I no longer take ESD lightly.
I think there are two reasons why I didn't realize the importance of ESD in the first place. The first reason is the weather. Vietnam and where I started working on IC are both tropical countries. With temperatures always above 30 degrees Celsius I can survive with just a shirt and a pair of pants. But where I work now, and where I start to be exposed to ESD regularly, is different. I have to put on at least 2 layers of clothes, including a layer of wool or felt, when it is cold. And the problem starts here. When I move or move, the layers rub against each other and create static electricity - the same way I did static electricity on a student pen. When I take off my outer coat, the rubbing creates even more electrostatic (sometimes static electricity causes the hairs on my body to stand up like Simon-ku). If I were to accidentally come into contact with a metal conductor (usually a doorknob), I would definitely startle me at the same time with a loud "slap" sound due to the amount of electrical charge on my body. I ejected (and followed by something from my mouth).

First of all, the weather sounds funny, because the weather has nothing to do with ESD. Just like if I say the second reason is because in Vietnam I ride a two-wheeled vehicle, then I ride a "two-wheeler", and now I ride a four-wheeled vehicle, whoever believes. In fact, when I walk, my clothes can't rub anything to create static electricity. When riding a two-wheeled vehicle in Vietnam, my pants are sandwiched between two layers of leather (mine and the saddle) so nothing can accumulate. Four-wheel drive is different, especially in my antique car, with felt upholstery. Just about half an hour of sitting on that chair, with swivel movements when cornering, swaying along with the music as the car goes straight, is enough to generate an amount of static electricity that can numb my arm. just before I could touch the door handle to close the door.
In short, I am slow to "enlighten" about ESD because it is a matter of ... Western: cold places, houses are carpeted, commuting with cars. In Vietnam, I played all shorts, with three holes, brick floors, luckily, riding a car with a back with ... meat, where would ESD be dug. But after being electrocuted by ESD several times I believe ESD is a matter of concern. Who is sure that the amount of static electricity is enough to make a person weighing several tens of kilograms to jump back up unharmed for a few grams of electronic chip?
