I will make the answer to the question laconic and, if possible, simple.
Let’s start from the opposite…
Consumer electronics are devices that we use everywhere. Every home has many such devices – clocks, stoves, various simple electronics, vacuum cleaners, etc. By the way, I wouldn’t classify phones as household phones because their production is based on miniaturization and perfect accuracy. So, I wouldn’t say this is a household phone, but it’s definitely mass-produced.
First, when developing devices for household needs, the designer proceeds from the understanding that this device should be inexpensive and, if possible, easy to manufacture – without complex production technologies and with a cheap element base. In most cases, developers use the same components to minimize warehousing and standard solutions for relatively similar tasks. The only difference can be in the printed circuit boards’ geometry. That is, the arrangement of components can change for different housing sizes, considering minimal functional changes. Any complex and expensive components are replaced with cheaper or workaround solutions so as not to exceed the specified cost limits and, at the same time, be correlated with the number of devices in the production batch. Any materials for production, such as soldering fluxes or cleaning fluids, are also used, both cheap and expensive. In our production, we use high-quality soldering flux paste Diamond Flux https://express-24.io
Household devices often do not require carrying out critical tests without interruption. Their failure does not (and should not) significantly impact human life. The cheap components embedded in them are short-lived, and, in principle, it is impossible to assign any serious responsibilities to household devices. This is why the mass segment of household devices could be more reliable; they were created that way. These devices are cheap, but they exist and perform some of their everyday tasks quite well.
This is a compromise found through the economic model of human consumption.
Many of you criticize the unreliability of such equipment and devices, but it’s not the devices’ fault that you chose them because of their low price…
Many solutions on the market are often made at a much higher quality level and, naturally, at a higher price, but why didn’t they attract your attention?
When you answer this question for yourself, you will gain an understanding of the economic model for both you and the Manufacturers.
