The laser marking machine has been widely applied in many industries for the marking of a variety of products. Cell phone manufacturing is not an exception.
The laser marking machine is almost used for marking every component of a cell phone, such as the surface of phone shells, logos, batteries, relevant decorations, integrated circuits, and metal conductive components. That is, both interior and exterior parts can be processed by the machine. The engraving of QR codes with unique contents is one main application for the purpose of curbing the production and circulation of counterfeit smartphones. The marking quality of laser marking machines is more premium than that of inkjet coding processing as well as silk-screen printing although the marking effect looks similar.
Prior to the invention of the laser marking machine, silk-screen printing is one of the important methods utilized to mark the surface of numerous commodities. This means has numerous disadvantages by comparison with the laser marking machine, including being easy to be removed and low precision. That is, the processing quality is inferior. In addition, Inks composed of heavy metal chemicals are used for silk-screen printing, which increases the risk of environmental pollution. The laser marking machine, in contrast, satisfies the need for low carbon and environmental protection and marking contents, such as graphics, patterns, and texts, are permanent, thereby enhancing anti-counterfeiting and rising in value.
With the development of laser marking technology and laser marking machines, silk-screen printing has been replaced by the laser marking machine to yield more economic and environmental benefits. This type of machine can be applied for precise marking and its advantages are unmatchable by other conventional methods, such as silk-screen printing, mechanical scribing, and EDM. These benefits include maintenance-free, high flexibility, high reliability, and high performance. The laser marking machines are more suitable for industries with the requirements of high precision, depth, and smoothness due to these advantages. This is why the smartphone industry has used it for the marking of various components.
Personal electronic products represented by cell phones have been greatly changing and facilitating people’s lives, and functionalization and intelligence are the main directions of cell phone development. With the technological progress of the microelectronics industry and people’s demand for personalized cell phones, fine laser marking processing technology and the laser marking machine will play an increasingly important role in the manufacture of cell phones. Meanwhile, the laser marking machine is also promoting the development of other microelectronics manufacturing fields.
