PCBA has a strong presence in the manufacturing industry, and any electronic product production is inseparable from the PCB process. On PCBA (printed circuit board assembly), laser engraving 5*5mm*** needs to choose a suitable laser marking machine. This article will introduce which machine to use for laser engraving 5*5mm*** on PCBA and related applications.
1. Choose the right laser marking machine.
When choosing the right laser marking equipment, you need to consider the following factors:
1. Laser power: Laser power is an important indicator to measure the performance of the laser marking machine. Generally speaking, the higher the laser power, the faster the marking speed. Therefore, when choosing laser marking equipment, you need to choose the right laser power according to the size and material of laser carving, PCBA is different from hard metal, and you don't need to choose too high power.
2. Laser wavelength: different materials have different laser absorption rates for different wavelengths. Generally speaking, CO2 laser marking equipment is suitable for non-metallic materials, while ultraviolet laser marking equipment is suitable for marking with high accuracy requirements.
3. ** and maintenance costs: different brands and models of laser marking equipment ** and maintenance costs are different. It is easy to buy an inferior machine if it is too low, and it is not necessary to buy an inferior machine if it is too high, so when choosing laser marking equipment, you need to consider its cost performance and later maintenance costs.
In the market, there are a variety of laser marking equipment that can meet the needs of laser engraving 5*5mm***. Among them, some common models include: CO2 laser marking machine, ultraviolet laser marking machine, etc. Ultraviolet laser marking equipment has high precision and speed, suitable for marking and marking of various materials, and its accuracy can be 002mm, marking 5*5mm *** is no problem.
Second, the application case.
The following takes a company as an example to introduce its application of laser engraving 5*5mm*** on PCBA:
In order to meet this demand, the company chose ultraviolet vision laser marking equipment. The equipment has the characteristics of high power density, high scanning speed, automatic positioning, identification and marking, etc., and can quickly complete the laser engraving task. At the same time, the equipment also has the advantages of simple operation, convenient maintenance, etc., no need to manually visit one by one, the system automatically locates and marks, and also adds the functions of foolproof, error-proof, automatic scanning, etc., which greatly reduces the company's production cost and improves the marking quality.
