Laser Marking in Electronics

Laser marking and cleaning machines are becoming core tools in the electronics manufacturing industry. From marking printed circuit boards with micron-level precision to finely etching metal casings, to cleaning precision components without damaging them, these machines improve production efficiency and solve environmental problems associated with traditional manufacturing processes.UV technology is especially suitable for the miniaturization trend in electronics, and its non-contact nature guarantees a high yield of quality components. It is reshaping the production processes of 3C products.

The unique advantage of laser technology for the electronics industry.

Compared to traditional processing methods, laser marking and cleaning machines are "black technology" in the electronics industry.Not only can they perform non-contact processing to avoid scratching delicate parts, they can also be adjusted to achieve millimeter-precise operations.What ’ s even more important is that the entire process is environmentally friendly. It uses no chemical agents and produces no waste, so factories can use it with peace of mind.

These are the three main applications of laser engravers.

Information markers for circuit boards.

The QR codes and serial numbers on the circuit boards of mobile phones and smart watches are so tiny that it takes only 0.5 seconds for a fiber laser marking machine to complete them.This type of permanent marking is also heat-resistant and corrosion-resistant, so that the mark will not become blurred even after passing through the reflow soldering process.

Customized metal cases.

Today many Bluetooth earphone cases and battery chargers are engraved with a brand logo or customized design.The UV lasers can easily engrave delicate patterns on the surface of aluminum, with a more durable effect than silk-screening, and not easily damaged by daily wear.

Tracing counterfeit high-tech components.

For high-value components such as mobile phone camera modules, manufacturers use a laser to engrave a counterfeit-proof code on the metal frame.These micron-level markings are difficult to counterfeit and can be scanned to trace the production batch, effectively preventing the circulation of refurbished parts.

Laser cleaning machines solve industry headaches.

During the assembly of electronic products, soldering residue and oxidation layers are often encountered.Traditional manual polishing can easily damage parts, but the laser cleaning machine is like a "precise eraser," removing only the contaminants and leaving the base material undamaged.In particular, when cleaning flexible circuit boards (FPCs), the efficiency of the process is more than three times that of the chemical immersion method.
