Printed circuit boards (PCBs) are an indispensable component of modern electronic devices. They are used to connect various electronic components for products such as mobile phones, laptops, computers, and other consumer electronics, including game consoles and smart home devices. As boards become increasingly complex in their layout, the value of the electronic components and chips used on the board has increased. Identification of the board is essential to ensure authenticity, traceability, and identification, but what process should manufacturers be using? By using the right process, manufacturers can protect their products from knock-offs, add identification traceability, and ensure that consumers receive safe and functioning products.

Laser marking vs. PCB labeling: what is the difference?

Traditionally, in PCB assembly, applying labels to boards is a manual task to identify the original intended use or even to define the version of the board being produced. Label application is very time-consuming and can be error-prone if manually carried out. However, since PCB labels are tiny in size and hard to handle. Finding a machine to handle this operation can be challenging. Moreover, even if a machine could apply these labels, they would not be secure forever, as they could fall off over time, get scratched, experience ink fade, or simply fall off the board. In contrast, laser marking modules are able to accurately scan and locate the positions where the laser should mark and override durability issues since the information is laser-etched directly onto the PCB itself. This method offers several benefits over traditional labeling, including increased accuracy, improved efficiency, and reduced errors.

By replacing labeling with laser marking, manufacturers can streamline the assembly process, reduce production time, and improve the quality of their products. But let's take a closer look at the benefits.

Increased automation and efficiency

One of the most significant factors in any production is to increase throughput and optimize processes to improve production efficiency. Instead of creating a bottleneck with a manual workstation and operator, or worse, unloading stacks of boards to be manually labeled, adding automation such as a laser marker brings a lot of value to the board assembly process. 

How Laser Markers Work

Laser markers are designed to only etch the surface of a board, not burn holes through it. Reputable manufacturers offering laser marking modules should provide sample markings for your review and testing.

Technically speaking, a laser beam is directed across the surface of the circuit board, and the reflection is captured by a sensor. The data obtained from the reflection is then used to create an accurate 3D circuit board map. This technology can measure to an accuracy of a few micrometers, allowing for a level of precision that is impossible with manual labeling. This increased accuracy is crucial in ensuring the circuit board is correctly marked and completed with visual inspection cameras.

Improved traceability & serialization

An advanced laser marker system can be connected to a company's EMS system, which then can provide serial numbers to allow for serialization and full traceability of a PCB. This meets the safety and security needs of industries requiring a higher data granularity, such as defense, medical devices, and automotive, to name a few. In fact, many companies in these industries are opting for laser marking solutions due to their increased reliability compared to manual labeling.

Better quality control

The manufacturer should provide software and a user-friendly interface to allow you to store barcodes, auto-serialize, create 2D barcodes, or even upload a company logo for marking. Your vendor should offer a range of tools, from human-readable markings to standard barcode types, to facilitate a quick start.

Overall, incorporating laser marking technology in PCB assembly is a practical and effective solution for improving production processes' efficiency, speed, and quality. It provides the ability to identify and tracking boards while eliminating manual processes. The reliability and consistency of laser marking enhance the quality of boards produced, making it a preferred option for manufacturers assembling PCBs and for their customers.

The Application Advantages of Laser PCB Marking System

Posted on PCB, also known as printed circuit board, serves as the provider of electrical connections for electronic components and is a core component of electronic devices. It is applied in various industries such as medical equipment, industrial machinery, lighting, automotive core components, 3C electronics, aerospace, etc. Therefore, the identification process of PCB in production manufacturing naturally cannot be neglected. Currently, the traditional method of traceability involves using barcode labels, which requires barcode paper and printing, followed by manual or machine application. This process is cumbersome, prone to errors, lacks detection capabilities, and the labels can easily become detached over time. Laser marking machines, as a new identification technology, are favored by PCB manufacturers. Laser marking requires no consumables, has low costs, fast speed, and provides permanent marking. Its efficiency, high speed, and clarity bring significant advantages to PCB manufacturers. The Laser PCB Marking System is capable of marking QR codes, barcodes, production dates, usage information, and other content on PCBs. A 355nm cold light laser, it can use laser beams to burn traces on the surface of PCBs without contacting the product surface, thereby achieving the marking effect. So, what are the application advantages of collaboration between laser equipment and the PCB industry?

1. High-precision marking technology.

Traditional marking methods rely heavily on manual operation, which often leads to positional deviations, blurred fonts, and overlapping issues, significantly impacting product quality and reliability. Laser marking equipment can precisely and clearly engrave both small fonts and complex graphics on PCBs through laser beam irradiation.

2. Improved production efficiency.

Laser marking machines can be upgraded to automatic marking, enabling batch production and customized design by quickly and precisely identifying products according to different requirements. This high-speed production mode helps manufacturers reduce costs and enhance product competitiveness.

3. Anti-counterfeiting applications.

It's well known that counterfeit products bring significant negative impacts to consumers and legitimate manufacturers, not only reducing user satisfaction but also harming the reputation of manufacturers. The anti-counterfeiting markings created by laser marking can effectively prevent such occurrences. Laser devices are classified based on laser medium into solid-state lasers, gas lasers, semiconductor lasers, and dye lasers. According to the laser wavelength, they are categorized into ultraviolet, CO2, fiber, and green lasers. Carbon dioxide (CO2) lasers are primarily used in consumer electronics, mobile components, ceramics, PCBA, and plastic casings. CO2 laser devices typically operate at 10W, with a wavelength of nm and a laser spot size of 0.08mm. Fiber (FLP) lasers are primarily used for translucent plastic buttons, watches and glasses, electronic components, hardware accessories, building materials, screen covers, etc. Fiber laser devices typically operate at 20W, with a wavelength of nm and a laser spot size of 0.05mm. Ultraviolet (UV) lasers are mainly used for process gifts, pharmaceutical packaging, food and beverage packaging, PCBA, screen covers, steel sheets, etc. UV laser devices typically operate at 5W, with a wavelength of 355nm and a laser spot size of 0.03mm.
