The application prospect of 355nm UV laser source in the mobile phone industry

Laser marking machines have been used in product marking in many industries, and the mobile phone manufacturing industry is no exception. Today, we will take the iPhone, which everyone is very familiar with, as an example to explain the laser marking machine for mobile phones. 5, 5s, 6, the recently released 8. Every accessory of iphone products is basically processed by laser marking machine. For example, inside the iphone5 mobile phone case, IC, and metal conductive bits, there are QR codes with unique content engraved with them to prevent the imitation of counterfeit products. Then look at the black font of the manufacturer and serial number area on the back of the iPhone, which looks similar to the ink printed on it at first glance. But in fact it is neither ink jet coding nor silk screen printing. That's right, this is also laser-processed. The shell of the iPhone is made of aluminum oxide, commonly known as aluminum oxide blackening.

So what other applications do laser marking machines have in the mobile phone industry?

1. Hardware decorative sheet and mobile phone case

The laser marking machine can not only mark LOGO, product information, etc. on the hardware decorative sheet and the shell, but also can make special effects such as reticulation and wire drawing, and the marked lines are more delicate and the patterns are more delicate. The repetition frequency of other laser marking machines is higher, which can greatly improve the marking rate.

2. Mobile phone light transmission button

The transparent keys made of silicone are used, which are highly sensitive to laser power. As usual, the pulse sequence of the laser marking machine is not stable, and it is easy to cause uneven marking and affect the transmission result. Adopting the end-face pump structure and adding pulse controllable technology can make it form a stable pulse sequence, and the light transmission color is more uniform.

3. Finished products such as chargers and batteries

Laser marking machine can be used to mark LOGO, product information, etc., including serial number, production date and batch number, barcode, QR code, etc.
