All of us have heard the warnings to make sure we are properly grounded when working on our electronic devices, but have advances in technology lessened the problem of static electricity damage or is it still as prevalent as before?
In the industry, it is known as Electrostatic Discharge (ESD), which is now a problem more than ever before, although the recently adopted policies and procedures have helped to reduce the possibility of ESD damage to the product. In any case, its impact on the electronics industry is greater than the other industry.
This is also a big learning topic, very complicated, so I will click a few points. If you are interested, there are many free resources, materials and specialized websites. Many people dedicated their careers to this field. Products affected by ESD are very real and very influential for all companies involved in electronic products, both as manufacturers, designers and as "consumers", as well as many things in the industry, Passed on to us.
It is also a huge topic of study and very complex, so I will just touch on a few points. If you are interested, there are numerous free sources, materials, and websites dedicated to the subject.

Products damaged by ESD have a very real and very large impact on all the companies involved in electronics, whether it is as a manufacturer, designer, or “consumer”, and like many things dealt with in an industry, its costs are passed along to us.
From the ESD Association:
As the size of the device and its features become smaller, they become more susceptible to ESD damage, which makes sense after some thought. The mechanical strength of the material used to build the electronic device generally decreases as the size decreases, and the ability of the material to resist rapid temperature changes is often referred to as thermal mass (as in macroscopic objects). Around 2003, the smallest feature size in the 180nm range, and now we are fast close to 10nm.
It does not seem to be a problem for consumers who are not working or understanding in the electronics manufacturing sector. When most of the electronic products are packaged and sold, there are many security measures to prevent most ESD damage. Sensitive components are physically unreachable and have a more convenient ground channel (ie, the computer chassis is connected to the ground, the ESD discharge to which it will almost certainly not damage the CPU inside the chassis, but instead replace the lowest resistance path Grounded by power and wall power). Or that there is no reasonable current-carrying path is possible; many phones have non-conductive external and have only a grounded path at the time of charging.
That is why we need to install static eliminators to decrease the damage of the static.
