In the past 10 years, laser coding has been increasingly used in the printing of circuit board PCBs. In order to improve the yield and product quality of electronic products, circuit board manufacturers have used laser coding equipment to use raw materials on circuit boards. The QR code is automatically generated by purchasing, production process and technology, product batch, manufacturer, production date, product destination and other information. It is automatically marked on the PCB / FPCB surface by laser to achieve product quality control and traceability.

Laser PCB board coding
Compared with screen printing (referring to the use of silk screen as the base, and the use of photosensitive plate-making method to make screen printing plates with graphics), laser PCB board coding has better accuracy and flexibility, Can make up for the lack of silk screen processing, greatly improve production efficiency and yield, reduce costs and reduce pollution.

Laser marking processing, as a new and high-tech method of marking processing, has incomparable advantages over traditional processing methods. Unlike traditional processing methods, laser processing uses a high-energy-density laser to locally irradiate the workpiece to vaporize the surface material or A marking method in which a color-changing chemical reaction leaves a permanent mark. Laser marking can produce a variety of text, symbols and patterns, and the character size can be on the order of millimeters to micrometers. This can effectively prevent counterfeiting of the product. For the current PCB industry, it is undoubtedly not one of the best processing solutions. Whether it is fine processing, processing efficiency, and processing results, it completely meets the needs of current PCB marking processing.

Has been widely used in digital products, wearable devices, automotive circuit boards and many other fields.

So, how to choose the two-dimensional code mark of the circuit board of the manufacturer to choose the laser coder that suits you, everyone is pursuing high cost performance, then the applicability and price must be considered. Here the media has compiled the following points for everyone for your reference.
1. First look at the laser equipment manufacturers in the subdivided field. Laser equipment manufacturers specializing in the circuit board industry have rich experience in landing, and choose models for you more efficiently and quickly.
2. Look at the coding efficiency, because this directly affects the product processing capacity and labor time cost.
3. Look at the processing methods and functions, because different equipment, tooling and automation, positioning function modules are different.

After the above three points, we are looking for high-quality laser coding machine brands to cooperate, so that laser coding can be better used on PCB circuit boards. Its main applications can be in various oils such as white oil, green oil, black oil and copper. The surface of the material is automatically engraved with a QR code. Today, you can automatically generate a QR code from the raw material purchase, production process and process, product batch, manufacturer, production date, product destination and other information, and automatically engraved on the PCB surface by laser, greatly improving production efficiency and saving labor costs for you .
