Difference between green laser, blue laser, UV laser and fiber laser

In the current laser market, there are quite many kinds of laser sources. They all have different applications and what they can achieve and what they can work on are also different. Today, we are going to talk about the difference between green laser, blue laser, UV laser and fiber laser.

For blue laser and green laser, the wavelength is 532nm. They have very small laser spot and shorter focal length. They play an important role in precision cutting in ceramics, jewelry, glasses and so on. 

For UV laser, the wavelength is 355nm. Laser with this wavelength is almighty, meaning it can work on nearly any kinds of materials. It also has very small laser spot. Because of its unique wave length, UV laser can perform laser cutting, laser marking and laser welding. It can do the job that fiber laser or CO2 laser can’t do. UV laser is particularly suitable for laser processing that requires ultra-high precision and clear & burr-free surface. 

Fiber laser has a wave length of 1064nm and plays an important role in metal cutting and welding. And its laser power continues to grow year by year. By now, the biggest fiber laser cutter has reached 40KW and completely replaced traditional wire-electrode cutting technique.

No matter what kind of laser source it is, it tends to generate heat. To take away the heat, a water cooling chiller would be ideal. S&A Teyu develops water cooling chillers suitable for cooling different kinds of lase sources. The recirculating water chiller ranges from 0.6KW to 30KW in terms of cooling capacity and offers different temperature stability for selection -- ±1℃,±0.5℃, ±0.3℃, ±0.2℃ and ±0.1℃. Different temperature stability can meet different temperature control demand of different kinds of lasers. Go find out your ideal laser water chiller at https://www.teyuchiller.com

Why water cooling is more preferred by laser users than air cooling?

As we know, laser is a heat generating component. The bigger the power, the more heat it will generate. Some small power lasers only need air cooling to dissipate the heat effectively. However, as the power increases, air cooling is not sufficient to take way the heat and that needs water cooling. Water cooling is more preferred by laser users in that it is less noisy and the temperature can be regulated. By water cooling, we often refer to industrial water chiller. Among the laser users, one of their favourite small industrial water chillerwould be CW-3000 laser chiller. It is energy efficient and can bring down the temperature of the laser to the ambient temperature.

Why the PCB market can bring great development for the laser industry?

The laser processing market scale seems to grow slowly in the past two years. However, there is one laser market which is still developing in a rapid speed -- PCB processing related laser market. So how is the current PCB market? Why can it bring great development for the laser industry? 

PCB and FPC industry with rapid development and huge market demand

PCB is short for printed circuit board and is one of the most important parts in the electronics industry. It exists in almost every electronic product and is used for electrical connection for each components. PCB consists of insulating baseboard, connecting wire and the pad where electronic components are assembled and welt. Its quality decides the reliability of the electronics, so it is the foundation industry and the biggest segment industry for the electronics industry.

PCB has a wide application market, including consumer electronics, automobile electronics, communication, medical, military and so on. For the time being, consumer electronics and automobile electronics are developing so fast and they become the major applications for PCB. 

Among the PCB application in consumer electronics, FPC has the fastest growing speed and taken up bigger and bigger market share of the PCB market. FPC is also known as flexible printed circuit. It is a highly reliable and flexible printed circuit board which uses PI or polyester film as the foundation material. It features light weight, high density of wire distribution and good flexibility, which can perfectly meet the intelligent, thin and light trend in mobile electronics. 

The fast growing PCB market leads to a big derivative market. With the development of the laser technique, laser processing gradually replaces traditional die cutting technique and becomes an important part in the PCB industry chain. Therefore, in this big environment where the whole laser market has slow development, the PCB related laser market is still developing fast. 

Advantage of laser processing in PCB and FPC

Laser processing in PCB refers to laser cutting, laser drilling and laser marking. Comparing with traditional die cutting technique, laser cutting is non-contact and doesn’t require expensive mold and can achieve high precision with no burr on the cut edge. This makes laser technique the ideal solution for cutting PCB and FPC. 

Originally, laser cutting in PCB adopts CO2 laser cutting machine. But CO2 laser cutting machine has big heat affected zone and low cutting efficiency, it did not have wide application. But as the laser technique continues to develop, more and more laser sources are invented and can be used in PCB industry. 

For the time being, the commonly used laser source used in PCB and FPC cutting is nanosecond solid state UV laser whose wavelength is 355nm. It has better material absorption rate and smaller heat affected zone, which enables to achieve higher processing precision.

To reduce charring and achieve higher efficiency, laser enterprises continue to develop UV laser of higher power, higher frequency and narrower pulse width. So later 20W,25W and even 30W nanosecond UV lasers were invented to better meet the increasing demand in the PCB and FPC industry. 

As the power of the nanosecond UV laser becomes higher, the more heat it will generate. To maintain the optimal processing performance, it requires a precise laser chiller. S&A Teyu water cooling chiller CWUP-30 is capable of cooling nanosecond UV laser up to 30W and features ±0.1℃ stability. This precision enables this portable water chiller to control the water temperature very well so that the UV laser can always be in a suitable temperature range.

What is the lowest temperature for industrial process chiller which cools injection molding machine?

The available temperature control range for industrial process chiller which cools injection molding machine is 5-35 degree Celsius. But if the water cooling chiller is going to be set at 5 degree Celsius in a long period, users need to choose a bigger one. For example, in normal condition, using S&A Teyu industrial process chiller CW-5200 would suffice to cool an injection molding machine. But if users would like to set the chiller to 5 degree Celsius, it is suggested to choose CW-5300 whose cooling capacity is much higher than the heat load of the injection molding machine.

Note that setting the water temperature at 20-30 degree Celsius can help prolong the life of S&A Teyu industrial process chiller. 

After 19-year development, we establish rigorous product quality system and provide well-established after-sales service. We offer more than 90 standard water chiller models and 120 water chiller models for customization.

Laser marking technique is applied in bathroom ceramic product

As the living standard improves, people also have higher requirement for their life. For bathroom ceramic products, many people would like personalizaion. With laser marking technique, this requirement can be easily met.

How to laser mark on bathroom ceramic product

As we know, when posting laser light on ceramic, there will be diffuse reflection (almost like total reflection). Therefore, ceramic is hard to absorb laser light. So how to make this happen? Some laser device manufacturers come up with a solution. They put on a layer of coating on the ceramic. When laser light is posting on the ceramic and the temperature reaches 800℃, the ceramic toner will penetrate into the ceramic glaze to realize the marking process.

Features of laser marking on bathroom ceramic product

1.Rely on computer to form the pattern and shape. Basically every marking is possible;
2.There are different kinds of bathroom ceramic products. The laser equipment can be transformed into portable style by using fibre transmission for more flexible work;
3.The marking produced by laser marking is long lasting, delicate, pollution free and low cost, which can increase the grade of the ceramic product.

Most of the bathroom ceramic product laser marking machines are powered by UV lasers and they are quite good at producing delicate markings. UV laser, just like other laser sources, also a heat generating component and is easy to become overheating. If the overheating is left unattended, critical failure is likely to occur. With S&A RUMP series water cooling chillers, you can easily fix this overheating problem. Plus, these chillers have a rack mount design and they can easily fix into the configuration of the UV laser marking machine, which is space efficient.
