UV laser - the multitasker in PCB manufacturing

3W, 5W,10W,15W,20W,30W.....Just as fiber laser, the power of UV laser has been increasing. In addition to increasing power, the current UV laser also has more features, such as narrower pulse width, multi-wavelength, bigger output power, higher peak power and better absorption by the materials.

UV laser can work on many different kinds of materials, such as plastic, glass, metal, ceramics, PCB, silicon wafer, coverlay and so on. In addition, Ultraviolet laser is a multitasker as well, for it can perform different tasks in different working procedures of a single material processing. Now we take PCB manufacturing as an example. UV laser can perform laser cutting, laser etching and laser drilling on PCB. 

1.PCB cutting

In coverlay and PCB cutting, UV laser is the most ideal option. Coverlay is used for environment insulation and electric insulation so that the fragile semiconductor on the PCB can be well protected. However, coverlay needs to be cut by certain shapes and using UV laser can avoid damaging the released paper. (Other processing methods can easily lead to the coverlay separating from the released paper). As we know, PCB or even flexible PCB materials are very thin and light. UV laser can not only remove the mechanical stress but also reduce the thermal stress to the PCB. 


2.PCB etching

It is quite a complicated process to make the circuit outline on the PCB and in this process, laser etching is needed. Comparing with chemical etching, UV laser etching has faster speed and is more environmental friendly. What’s more, the light spot of the UV laser can reach 10μm, indicating higher etching precision. 

3.PCB drilling

UV laser is widely used in drilling holes with diameter less than 100μm. As miniature circuit diagram is increasingly used, the hole diameter could be less than 50μm. In drilling holes with diameter less than 80μm, UV laser has the biggest productivity. 

To meet the increasing demand of micro hole drilling, many factories have already introduced multi-head UV laser drilling systems. 

The rapid development of UV laser results in the higher standards required for the cooling system

As we all know, the higher the temperature stability of the UV laser mini recirculating chiller, the less water temperature fluctuation will be. Therefore, water pressure will be more stable with less bubble occurred. In this situation, the UV laser can be well protected and its life can be extended. 

S&A Teyu CWUL and CWUP series Ultraviolet laser compact water chillers are the outstanding chiller models for cooling UV laser. For CWUP-10 and CWUP-20 UV laser chillers, the temperature stability could reach ±0．1℃, indicating ultra-precise temperature control for the UV laser.
