Advantage of using laser marking technique in PCB industry 2021-03-04

air cooled chillers

As the rapid development of IT industry, smart phone and wearable electronics are heading towards the direction of “smaller and lighter”. This require the core component -PCB to be very demanding. To better control the production quality of PCB, laser marking QR CODE on PCB has become a trend in the industry. 

Traditional printing technique is gradually falling behind, for it is polluted, less delicate, less precise and worse abrasive resistance. And at the same time, a novel marking technique is gradually replacing traditional printing technique and becomes the main tool in PCB industry. And that is laser marking machine

Advantage of laser marking machine

The advent of laser marking machine solves a series of problems of traditional printing machine. Comparing with traditional printing machine, laser marking machine has the following advantages:
1.Excellent abrasive resistance. The marking produced by laser marking technique be various kinds of complicated logo, pattern, QR code, words and it is engraved on the surface of the materials directly, so the abrasive resistance of the marking is pretty good.
2.High precision. The diameter of the light spot of the focalized laser light can be smaller than 10um (UV laser). This is pretty helpful in dealing with complicated shapes and precision processing.
3.High efficiency and ease of use. Users just need to set some parameters on the computer and other work is pretty much done by the laser marking machine. This process generally takes a few seconds.
4.No damage occurred. Since laser marking machine is non-contact processing, so it won’t cause any damage to the surface of the materials.
5.Wide application and friendly to the environment. It can be used in different kinds of metal/non-metal materials without causing any pollution. 
6.Long lifespan. 

UV laser marking machine and CO2 laser marking machine in PCB industry

In PCB laser marking, the most commonly used is CO2 laser marking machine and UV laser marking machine. They both feature small heat-affecting zone, high precision, excellent processing effect and high speed, making them the first option in PCB surface marking. 

Laser marking QR code on PCB can maintain the trackability of the production, processing technique and the quality of the PCB and can meet the requirement of automation and intelligent production. 

Although UV laser marking machine and CO2 laser marking machine use different laser sources, they share one thing in common - the laser source is a “heat generator”. If the heat can not be removed in time, the laser output will be affected, leading to poor marking performance. To avoid this situation, one can equip their laser marking machines with air cooled chillers, like S&A Teyu chillers. S&A Teyu air cooled chillers offer rack mount type and stand-alone type for selection. For more information, please click
