Why Are Circuit Boards Inside Electronic Devices Green?

When we say circuit board, the image that comes to our mind will most likely be green. Of course PCBs in different colors There are, but most of them are green.

Actually, this is related to the reason of the issue “That’s exactly why.” There is no clear reason we can say, but There are some plausible theories. Let’s see which of these will make the most sense to you?

First of all, it is useful to learn: What is solder resistance?

Solder is a homogeneous substance formed by the combination of tin and zinc. Electronic components connected to traces or other components on the circuit board are applied by the welding process we call soldering. The high temperature that occurs when soldering an electronic temperature resistant coating is the solder resistance.

So what does this have to do with the color green?

glass epoxy

Glass epoxy, a material historically used to create solder masks, is inherently green in color. It is predicted that it will be green after a while. a color that the industry has become accustomed to It became the standard as “This is how it is, this is how it goes.” With this in mind, green was always used.

It has also become more cost-effective since green solder mask materials are now standard. Thus a it went into a loop and green material was naturally more preferred.

Another reason is entirely related to the nature of the green color.

green color, It has the highest contrast and is the least tiring on the eyes. between colors. We can read the symbols, texts and numbers on a printed circuit board with a green background much more easily.

One theory is that the military also has a role.

According to some sources, the US military concluded that the most effective circuit board was green. Therefore for circuit boards used for military purposes green color was chosen.

Manufacturers who supplied circuit boards to the military also served other customers. These companies, which do most of their business for the military, provide less costly and redundant He gave me green covered cards.

PCBs in other colors are also available.

Color of the printed circuit board; a company’s production standards, It may vary depending on the brand or simply your preference. Common alternative colors other than green are white, black, red and blue.

For example, black circuit boards found in iPhones; Makes text, symbols and numbers easier to see but it increases the heat.
