Marking PCB with UV laser

 Nearly each piece of Printed Circuit Board (PCB) involves more or less marking technique. That is because the information printed on the PCB can realize the function of quality control tracing, automatic identification and brand promotion. These information used to be printed by traditional printing machines. But traditional printing machines use quite a lot of consumables which can easily cause pollution. And the information they print become faded as time goes by, which is not very helpful.

But for laser marking machine, those problems are not problems any more. Laser marking machine features the non-contact processing, high speed, no consumables and no pollution. It can realize very clear, precise and long lasting markings on very tiny format up to 3x3mm. Besides, since it doesn’t have direct contact, it won’t cause any damage to the PCB.

The common PCB laser marking machines are powered by CO2 laser and UV laser. Under same configurations, UV laser marking machine has higher precision than CO2 laser marking machine. The wavelength of UV laser is around 355nm and most of the materials can better absorb UV laser light rather than infrared light. In addition, CO2 laser is kind of a heat processing to realize the marking effect. Therefore, carbonization is easy to occur, which is harmful to the base materials of the PCB. On the contrary, UV laser is a “cold processing”, for it realizes marking effect by breaking the chemical bond via the UV laser light. Therefore, UV laser won’t damage the PCB.

As we know, PCB is quite small in size and marking information on it is not easy. But UV laser manages to do it in a precise way. This results from not only the unique feature of the UV laser marking machine but also the cooling system it comes with. A precise cooling system is of great importance in maintaining the temperature of the UV laser so that the UV laser can function properly in a long period of time. S&A Teyu compact chiller unit CWUL-05 is commonly used for cooling UV laser marking machine in PCB marking. This chiller features 0.2℃ temperature stability, which means the temperature fluctuation is pretty small. And small fluctuation means the laser output of the UV laser will become stable. Therefore, the marking effect can be guaranteed. In addition, CWUL-05 compact chiller unit is quite small in size, so it doesn’t consume much of the space and can easily fit into the machine layout of the PCB laser marking machine.

S&A Water Chiller Machine CW-5200 Helps Bring Down the Temperature of Laser Medical Equipment of an Egyptian Hospital

There are thousands of patients in the world struggling with different kinds of diseases and they need to be treated fast without any mistake. With laser medical equipment, doctors can perform surgeries or treatment with high accuracy and high efficiency. Therefore, laser medical equipment has been gradually introduced into hospitals. In addition to high accuracy and high efficiency, laser medical equipment is non-contact, which greatly minimizes the injury on the patients.

However, for the high accuracy and long-term performance, the temperature of the laser medical equipment needs to be brought down effectively. Mr. Abdul, a purchasing manager of an Egypt-based hospital, recently contacted S&A for a water chiller machine to cool the laser medical equipment. He learned from the partner of the hospital (a university in Egypt) that the water chiller machine produced by S&A can work very stably and effectively. In the end, he purchased S&A water chiller machine CW-5200 to cool the laser medical equipment. S&A compact chiller unit CW-5200 features the cooling capacity of 1400W and the temperature control accuracy of ±0.3℃ in addition to ease of use and long life cycle.

In respect of production, S&A has invested the production equipment of more than one million RMB, ensuring the quality of a series of processes from the core components (condenser) of industrial chiller to the welding of sheet metal; in respect of logistics, S&A has set up logistics warehouses in the main cities of China, having greatly reduced the damage due to the long-distance logistics of the goods, and improved transport efficiency; in respect of after-sales service, all the S&A water chillers are underwritten by insurance company and the warranty period is two years.

S&A Compact Chiller Unit CW-5200 for Cooling Package Sealing Machine

A perfectly sealed package can protect the goods inside and prevent the goods from being exposed to the humid and dusty environment. Therefore, many items like food, beverage and other kinds of groceries are packed in sealed package. All these sealed packages are done by the package sealing machine.

Mr. Chua works for a Singapore-based company which manufactures package sealing machines for food and sells them locally. Their package sealing machines are equipped with industrial water chillers which take away the extra heat from the sealing machines in order to extend the working life of the package sealing machine. Mr. Chua learned from his friends that S&A industrial chiller can be applied to many different industries and has compact design. He was attracted by the compact design and contact S&A for selecting the ideal model. At last, he purchased S&A compact chiller unit CW-5200 for cooling the package sealing machines. In fact, S&A compact chiller unit can be used to cool not only different kinds of lasers, but also laboratory equipment and other industrial process equipment.

In respect of production, S&A has invested the production equipment of more than one million RMB, ensuring the quality of a series of processes from the core components (condenser) of industrial chiller to the welding of sheet metal; in respect of logistics, S&A has set up logistics warehouses in the main cities of China, having greatly reduced the damage due to the long-distance logistics of the goods, and improved transport efficiency; in respect of after-sales service, all the S&A water chillers are underwritten by insurance company and the warranty period is two years.

S&A Compact Chiller Unit CWUL-05 for Cooling UV Laser

Mr Hien works for a Vietnam-based factory which is owned by a smart phone manufacturing company. This factory specializes in producing the mobile phone shells on which the smart phone logo and other details are printed by the UV laser markingmachine.

As we know, UV laser is getting more and more attention in the electronics industries due to its capability of performing accurate and permanent marking on various materials. However, UV laser will generate the extra heat during the operation and if the extra heat can not be removed in time, the normal working of the UV laser will be affected. Knowing this, Mr. Hien contacted S&A for purchasing the compact chiller units CWFL-05 to cool the 5W UV lasers of the UV laser marking machines. S&A compact chiller unit CWUL-05 is specially designed for 3W-5W UV laser and features constant and intelligent temperature control modes in addition to high temperature accuracy, compact design, ease of use and long durability. 

In respect of production, S&A has invested the production equipment of more than one million RMB, ensuring the quality of a series of processes from the core components (condenser) of industrial chiller to the welding of sheet metal; in respect of logistics, S&A has set up logistics warehouses in the main cities of China, having greatly reduced the damage due to the long-distance logistics of the goods, and improved transport efficiency; in respect of after-sales service, all the S&A water chillers are underwritten by insurance company and the warranty period is two years.
